Important Safety Instructions
WARNING: High energy and high voltage
Exercise caution when using and calibrating a power supply. High energy levels can be
stored at the output voltage terminals on a power supply in normal operation. In addition,
potentially lethal voltages exist in the power circuit and on the output and sense
connectors of a power supply with a rated output greater than 40 V. Filter capacitors store
potentially dangerous energy for some time after power is removed.
WARNING: Limitations on use
The XDC is not intended for use in connection with life support systems or other medical
equipment or devices.
CAUTION
Operate the power supply in an environment free of flammable gases or fumes. To ensure
that the power supply’s safety features are not compromised, use the power supply as
specified in this manual and do not substitute parts or make any unauthorized
modifications. Contact the service technician for service and repair help. Repairs must be
made by experienced service technicians only.
CAUTION: For use as a battery charger
When you are using any of these power supplies for battery charging applications, it is
essential to provide an appropriately sized fuse or circuit breaker in series between the
power supply output and the battery.
Installation of a protector (fuse or DC circuit breaker) rated for about 115% of the
maximum current rating of the power supply and designed specifically to interrupt the DC
voltage of the battery, will provide adequate reverse polarity current protection. Where
several power supplies are in parallel, it is best to fuse each one, rather than one large fuse
for all.

Basic Checks or Self-Tests
Basic Checks or Self-Tests
WARNING
The factory setting for Power ON is 0V and 0A with the output OFF. These settings can be
customized by end users. If you suspect that the power supply has been used by someone
else since it was received from the factory, be prepared for the unit to power ON with a
live DC output.
The functional test procedures described in this section include power-on and
front panel function checks as well as voltage and current mode operation checks.
Equipment Required
•
Digital Voltmeter (DVM) rated better than 0.05% accuracy.
•
DC shunt 1mV/A (±0.25%) with connecting wire. The recommended current
ratings for the DC shunt and the wire must be at least 10% more than the
output current of the power supply.
Display Test
To ensure that the display is working properly:
1. Turn the power switch ON.
2. Observe the display panel.
Every pixel should illuminate for 2 seconds as part of the power-on self-test.
If you need to rerun the test:
1. Turn the power switch OFF.
2. Wait until the pixels fade to black.
Some residual charge may remain in the capacitors after the power is OFF.
Waiting for the display to fade ensures that the capacitors have sufficiently
discharged their power to reset the power supply.
3. Turn the power switch ON.
4. Observe the display panel.
If you observe or suspect that one or more of the display pixels is malfunctioning,
contact the manufacturer.
Power ON Check
To complete the power on check:
1. Ensure that the AC power switch is OFF.
2. Connect the unit to an AC outlet.

protected to prevent accidental contact.
CAUTION
When making connections to the bus bars, ensure that each terminal’s mounting
hardware and wiring assembly are placed so they don’t touch the other terminal
and short the power supply outlet. Heavy connecting cables must have some
form of strain relief so the connections aren’t loosened and the bus bars aren’t
bent.
To complete the voltage mode operation check:
1. Ensure that the OUT OFF annunciator is illuminated. If OUT ON is
illuminated, press OUT ON/OFF.
2. Connect a Digital Voltmeter (DVM) to the output terminals on the rear panel,
observing correct polarity.
3. Press OUT ON/OFF to turn the DC output ON.
4. Slowly turn the Current knob clockwise 1 or 2 turns. Slowly turn the Voltage
knob clockwise and observe both the front panel voltmeter and the DVM. Do
not exceed 10V.
5. Compare the DVM reading with the front panel voltmeter reading to verify
the accuracy of the internal voltmeter. Both readings should be the same
within the accuracy of the meters. The minimum control range is from zero to
the maximum rated output for the power supply model. Check that the
Constant Voltage (CV) annunciator is illuminated.

Load Wiring
When connecting load wiring to the power supply, consider the following factors:
•
•
•
Current carrying capacity of the wire
Maximum load wiring length for operation with sense lines
Noise and impedance effects of the load lines
Current Carrying Capacity
As a minimum, load wiring must have a constant capacity greater than the output
current rating of the power supply. This ensures that the wiring will not be
damaged even if the load is shorted. Table 2-4. shows the maximum current
rating, based on 450A per square centimeter, for various gauges of wire rated for
105°C operation. Operating at the maximum current rating results in a
temperature rise of approximately 30°C for a wire operating in free air. Where
load wiring must operate in areas with elevated ambient temperatures or bundled
with other wiring, use larger gauges or higher temperature-rated wiring. For high
current applications, custom-designed bus bars are typically used. To increase the
current carrying capability, use parallel cables.

Load Wiring Length for Operation with Sense Lines
For applications using remote sensing, or for improved voltage regulation at the
load, you must limit the voltage drop across each load line. We recommend that
you use the larger load wiring to ensure a smaller voltage drop (1V maximum),
although units will compensate for up to 5V drop in each line with the remote
sense lines connected.

Load Wiring
Noise and Impedance Effects
To minimize noise pickup or radiation, use the shortest possible length of
shielded-twisted pair wiring for load lines. Connect the shield to the chassis via a
rear panel mounting screw. Where shielding is not possible or is impractical,
twisting the wires together offers some noise immunity. When using local sense
connections, use the largest practical wire size to minimize the effects of load line
impedance on the regulation of the supply.

Installation
Load Connections
WARNING
Exercise caution when operating the power supply. High energy levels can be stored at the
output terminals on a power supply in normal operation. In addition, potentially lethal
voltages exist in the power circuit and on the output and sense connectors of a power
supply with a rated output greater than 40V. Filter capacitors store potentially dangerous
energy for some time after power is removed.
CAUTION
When making connections to the bus bars, ensure that each terminal’s mounting hardware
and wiring assembly are placed to avoid touching the other terminal and shorting the
power supply outlet. Heavy connecting cables must have some form of strain relief so they
don’t loosen the connections or bend the bus bars.
Make load connections at the rear of the power supply at the positive and negative
output bus bars or to the 4-terminal wire clamp connector, depending on the
model. (See Figure 2-7.)
Wire Size
The wire should be one size larger than necessary to accommodate the required
output current. Normally, the next largest commonly used gauge is used. For
example, use 10AWG for 20A, and 8AWG for 30A.
Isolation
The wire must have a suitable insulating coating that will prevent arcing between
the positive and negative output current, and must be rated for 105°C operation.
Single Load
To connect a single load to the DC output bus bars (10–150V outputs):
1. Ensure that the power supply is powered OFF.
2. Place a bolt in the connecting hole of the negative bus bar, and fasten the
negative wire or bus bar, a washer, and a nut to the bolt.
3. Using a wrench, turn the bolt until it is secure at approximately 25 foot-
pounds (34Nm).
4. Fasten the positive wire or bus bar to the positive bus, using a bolt, washer,
and nut.
5. Tighten the bolt to approximately 25 foot-pounds (34Nm).

Load Connections
6. Ensure that the positive and negative wires are arranged so bare wires do not
come into contact with each other or the chassis.
To connect the DC output wire clamp connectors (300V, 600V outputs):
◆ Connect appropriately sized wires as described in steps 1 to 6 above, except
strip 0.5 in. (14mm) of insulation off each load wire, and clamp in the output
connector by securely tightening the vertical clamp screw for each output.
Multiple Loads
To connect multiple loads in parallel:
◆ Follow the “Single Load” procedure with the following exception:
To minimize interaction between loads, bring the wiring for each load directly
back to the supply output. When each load to the power supply is wired
separately, the loads will see only the precisely regulated output from the
supply. If 2 loads share a single cable, the fluctuation in current to one load
will cause the voltage to vary on the others. This is due to wire impedance
drops.

Installation
Remote Sensing
The power supply regulates the output voltage at the output connectors in its
normal configuration without remote sense lines connected.
Remote sensing lets the power supply track and regulate the output voltage at the
load, and thereby compensate for the voltage drop in the load lines. The power
supply will only compensate within the limitations of its voltage rating, to a
maximum of 5V per load line. Remote sensing is normally only required for
critical loads which cannot tolerate the slight voltage drop in the load lines caused
by their resistance. Remote sensing has no effect when the power supply is
operating in Constant Current mode.
Two remote sensing connectors are located on the rear panel of the power supply.
See Figure 1-6 on page 1–11 for location and polarity. Connect 2 wires from these
ports to the load, where the power supply cables terminate for your connection.
Carefully observe the correct polarity when making the connection. On
12000 Watt units, connect the sense wires to the connector on the top or master
power module.
The remote sensing input is sensitive to electrical noise, so always use a shielded
twisted pair, 22AWG or greater for the sense line cable. Terminate the shield to
the supply chassis or the negative output of the power supply for best results.

Operation
Overview
Once you have installed the power supply and connected both the AC input power
and the load as explained in Chapter 2, “Installation”, the power supply is in its
default configuration and is ready to operate in local control mode.
Powering ON the Power Supply
WARNING
The factory setting for Power ON is 0V and 0A with the output OFF. These settings can be
customized by end users. If you suspect that the power supply has been used by someone
else since it was received from the factory, be prepared for the unit to power ON with a
live DC output.
To power on the power supply:
1. Ensure that the AC power switch is OFF.
2. Connect the unit to an AC outlet.
3. Turn on the front panel AC power switch.
After a short power-on delay, the digital meters on the front panel and the CV
annunciator illuminate. The voltmeter and ammeter displays should read zero.
Check the front panel annunciators. If OUT ON is illuminated, press OUT ON/
OFF to disable it. The OUT OFF annunciator should now be illuminated. For an
illustration of the annunciators and their locations, see Figure 1-5.
Powering OFF the Power Supply
From the front panel, the safest method for shutting down the power supply is:

Power Supply Operating States
Power Supply Operating States
The power supply has 5 operating states:
•
•
•
•
•
Power-On
Output Shutdown
Soft Start
Normal Operation
Calibration
Power-On
This is the period between the time that AC power is applied to the supply (AC
breaker turned on) and the time that the power supply is ready for operation.
During this period, the internal circuits are powering up and performing self-tests.
At the end of the Power-On period, the supply is normally in its default Power-On
mode with the output OFF, VSET=0 and ISET=0.
Output
Shutdown
In this state, the output is disabled and there is no output regardless of power
settings. The power supply can be placed in the Output Shutdown state by a
command (via the front panel or from the programming interface), via the
Interlock signal, or from a protection mechanism. This is also called the Standby
mode.
Soft Start
In this state, the output power is ramping up gradually towards its target load. This
reduces equipment stress. This state occurs whenever the supply output is set to
ON or a protection state is re-set, and is approximately 2 seconds in duration.
Normal
Operation
This is the normal operating state for the power supply. The power supply is ready
to accept commands.
Calibration
This is a service mode that is used to calibrate setpoints and readback levels for
accuracy. Calibration should only be performed by qualified service personnel.
For detailed information, see Appendix B.

Operation
Power Supply Regulation Modes
The power supply has 3 regulation modes while in the Normal Operation State:
Constant Voltage (CV)
Constant Current (CC)
Constant Power (CP)
•
•
•
The CV, CC, and CP annunciators indicate the regulation mode.
Constant
Voltage (CV)
In this mode, the supply’s output voltage is constant while the current and power
vary with the load. The power supply will operate in constant voltage mode
whenever the load current IL is less than the current limit setting ISET, or: IL<ISET
(IL=VSET/RL). In constant voltage mode, the power supply maintains the output
voltage at the selected value (VSET) while the load current IL varies with the load
requirements.
.
Constant
Current (CC)
In this mode, the supply’s output current is constant while the voltage and power
vary with the load. The power supply will operate in constant current mode
whenever the load resistance is low enough that the load current IL is equal to the
current limit setting ISET. (VL=ISETRL). In constant current mode, the power
supply maintains the output current at the selected value (ISET) while the load
voltage VL varies with the load requirements.
Constant Power
(CP)
In this mode, the supply’s output power is constant while the voltage and current
vary with the load resistance. The power supply will operate in Constant Power
mode when the power drawn by the load is equal to the power setpoint and the
product of the voltage and current setpoint (VSET and ISET) is greater than the
power limit point (PSET). In Constant Power mode, the power supply maintains
the output power at the selected value (PSET) while the load voltage VL and load
current IL varies with the load requirements. The power limit is normally set to the
maximum supply rating, so the Constant Voltage or Constant Current modes will
always be in effect without entering into the Constant Power mode of operation.
Automatic
Mode
Crossover
This feature allows the power supply to automatically switch operating modes in
response to changing load requirements. If, for example, the power supply was
operating in Constant Voltage (CV) Mode (IL < ISET), and the load changed so the
load current (IL) became EQUAL TO the current limit setting (ISET), the power
supply would automatically switch into Constant Current (CC) Mode and the
output voltage would vary in response to changes in load current. If the additional
load was subsequently removed so the load current was again LESS THAN the
current limit setting, the supply would automatically return to Constant Voltage
(CV) Mode.

Remote Control Modes
Remote Control Modes
A number of control interfaces are available. You can control the power supply
remotely using 0–5V or 0–10V signals via the remote analog programming
interface or from a remote terminal using a remote digital interface. A remote
digital interface following RS-232 protocol is standard. An optional remote digital
interface following IEEE 488.2 (GPIB) protocol is also available. An optional
CANbus port is also available which enables multi-channel communication from
a single GPIB address, and supports current sharing with parallel connected units.
(For detailed information, see Chapter 4, “Remote Operation”.)
Front Panel Controls
The power supply is shipped ready to operate in local mode. The factory default
power-on setting is 0V, 0A with the DC output turned off.
This section describes the function keys, menu options, and control knobs that you
use to operate the power supply. (Additional details about the front panel keys,
control knobs, and display annunciators are provided in Chapter 1, “About The
XDC Power Supply”.)
The next section (“Power Supply Operation” on page 3–8) provides details about
configuring and operating the power supply.

Control Knobs
The Voltage and Current knobs are the simplest way to control the power supply.
The Voltage and Current knobs are digital encoders, and therefore, there are no
start or end points to their rotation, and their rotation positions are meaningless
when the power supply is powered OFF. The control knobs can be disabled
through a menu command. See “Lock Out Control Knobs” on page 3–44 for more
information.

Set Output Protection
Seven configurable protection mechanisms are available:
•
OVP: Over-Voltage Protection. Factory default = 103% VRATED
•
•
•
•
•
•
UVP: Under-Voltage Protection. Factory default = 0V (disabled)
OCP: Over-Current Protection. Factory default = 0A (disabled)
UCP: Under-Current Protection. Factory default = 0A (disabled)
OPP: Over-Power Protection. Factory default = 0W (disabled)
UPP: Under-Power Protection. Factory default = 0W (disabled)
Fold: Fold Protection. (See below.)
OVP shuts down the power supply if the protection limit is exceeded. The other
options offer a choice: they shut down the power supply or issue a warning. When
the protection level is set to zero, that mechanism is considered disabled.
However, in the case of OVP, a hardware protection mechanism still exists.
The last protection mechanism is Fold Mode protection, when the unit will shut
down if it enters the selected regulation mode for a specified period of time.
Other protection mechanisms designed to protect the power supply are:
•
AC Off: AC Off protection will disable the output if the AC line drops below
the acceptable range.
•
High Temperature Alarm: A High Temperature condition will queue an
alarm message when the temperature of critical internal components nears the
maximum operating temperature.
•
•
Over Temperature Protection (OTP): An over temperature condition will
disable the output.
Sense Protection: Sense Protection will disable the output when the internal
sense circuit is tripped by either reversed polarity at the output of the supply
or a high voltage present at the output.
•
Slave Shutdown Alarm: Slave Shutdown Alarm (12000 Watts only) will
disable the output when one of the protection mechanisms has been enacted in
the slave unit.
Recovery options are available for AC Off, OTP and Slave Shutdown.
Also, see “Status Registers” on page 4–43.

Power Supply Operation
Set Shutdown Recovery for AC Off and OTP
The Shutdown Recovery menu offers 2 options for AC Off (ACO) and Over-
Temperature protection (OTP):
•
Auto-Recovery: With this method, the power supply returns to its normal
operating state once the alarm condition no longer exists. For example, if
there was an over-temperature alarm and the protection was set to auto-
recovery, the power supply would return to its normal operating state once the
temperature was reduced below the alarm level.
•
Latched: With this method, the power supply remains in Shutdown state until
the operator manually clears the protection level and manually turns the
output back on.
You can set either or both the OTP and AC Off to Auto-Recovery or Latched.

If it is an OVP alarm, the unit shuts down.
2. If S/D if tripped? Nhas been selected, and it is not an OVP alarm, the
unit does not shut down but does create an alarm message.
3. If the unit is not shutting down, the system still sets the appropriate status bits
in the questionable status register, which can be queried remotely. See “Status

Operation
Set Up Remote Control
The power supply can be controlled locally with the front panel or remotely
through several different interfaces. The remote interfaces are discussed in
Chapter 4, “Remote Operation”, Appendix C, “SCPI Command Reference”, and
Appendix E, “GPIB”.
The factory default remote control setting is RS-232. It has a default configuration
of 9600 baud.
Toggle Local/Remote
The LCL/RMT key allows you to shift between local and remote control.
To shift from local to remote control:

RS-232
LCL/RMT
In the case shown, the power supply has changed from local, front panel control to
remote control through its RS-232 port. The remote control options are RS-232,
Analog V and I, Analog V, Analog I, GPIB, and Linked. You can change the
remote control source through the REMOTE SELECT menu option. (See “Select
Remote Control Source” below.)
There are 2 exceptions to this function:
•
If the power supply has Local Lockout (LLO) active, it will not let you shift
from remote to local control. Instead, the display will show LLO on, and the
system will remain in remote control.
•
If the system is using GPIB, it will shift to remote control only when the
Remote enable line, REN = 1 and a command is sent from the remote
controller.

Operation
Using Auto Sequencing
Auto Sequence programs can be set to run as a Power ON default or recalled from
memory by pressing the RECALL key. In Auto Sequence mode, 3 of the function
keys operate as alternates:
•
•
•
VOLTAGE operates as RUN/PAUSE.
CURRENT operates as TRIGGER.
STORE operates as END.
In the following discussion about running programs in Auto Sequence mode, each
of the keys mentioned above is referred to as their alternate function.
When an Auto Sequence program is launched from Recall, the AUTO SEQ
annunciator illuminates on the front panel. Press EXIT to return the unit to
normal operating mode.
Auto sequence programs can operate 3 different ways:
•
They can run automatically through a series of steps, repeating those steps a
pre-set number of times if necessary, and complete their operation without
intervention from an operator.
•
They can run automatically and be paused. If you need to stop the program
temporarily, you can press PAUSE to stop it, and then press RUN to resume
the program’s operation when ready. When a sequence is manually paused,
the Pause annunciator is illuminated. (The output remains on and voltage may
be present at the output.)
•
They can run automatically programmed to wait for a trigger at certain points
in the sequence. If you want the program to resume, you can press
TRIGGER or supply a trigger signal to the rear panel Trigger input. When a
sequence is paused by a trigger, the Trigger? annunciator is illuminated.
During operation, press the Up key to display information on the currently
running sequence including sequence number, step number, step parameters
(settings), the trigger source, as well as the loop count.

Power Supply Operation
Slew Rate
The slew rate is calculated as a function of change in the output voltage and a
given time interval. The maximum slew rate is 1% rated voltage/150us. The slew
rate is saved upon power off and restored at power on. Output ON/OFF and
shutdown are not affected by the programmable slew rate. These functions have a
slew rate of 1%/20ms.
The range of output voltage is 5% - 0.1% of rated voltage.
The range of time interval is 1.5 s - 150 us.
The negative slew rate is limited by the discharge rate of the output capacitors.
During current share, slaves operate with their default slew rate. The master
operates at its programmed slew rate. Hence a programmable slew rate for the
system is achieved. However, this slew rate is limited by the speed of the control
loop. The slaves will return to their programmed slew rate when they exit current
share slave operation.
The slew rate error increases as the slew rate increases.
Selecting SLEW RATE from the main menu will give you two choices:
Voltage slew - adjust the voltage slew rate
Voltage default -restore the default voltage slew rate
Selecting VOLTAGE DEFAULT will return the slew rate to the default value of
1% rated voltage per 150us.

The combination must not exceed 1%/30us. Though the software will attempt to
achieve higher slew rates, it is limited to this value by hardware constraints. The
power supply slew rate cannot be faster than the rise and fall times given in the
product specifications in Appendix A. Manufacturer's recommendation is to keep
the slew rate at or below the default value.

Multichannel functionality and explains how to send
commands to the power supply using the SCPI programming
language

Remote Operation
Overview
In addition to front panel operation, the power supply can be operated remotely
through the following interfaces:
•
•
•
•
Analog 0 to 5V, 0 to 10V
RS-232
GPIB (with optional GPIB/CANbus card)
Multichannel (with optional GPIB/CANbus card)
The connecting ports for these interfaces are shown in, Figure 1-6 and Figure 4-1.
The remote interfaces (except for the analog programming interface) accept
commands in 2 formats: IEEE 488.2 common commands and SCPI commands.
SCPI commands that are aliases for the IEEE 488.2 common commands have
been provided for use over the multichannel interface.
The IEEE 488.2 common commands that are supported are:
*CLS
*ESE
*ESE <enable_mask>
*PSC <on_off_state>
*RCL <user_setting>
*RST
*ESR?
*IDN?
*SAV <user_setting>
*SDS

Remote Operation
Remote Analog Operation
Analog Connections
The analog interface has 2 ports: the user lines and the analog programming lines.
The tables below show the function and power flow for each pin on these ports.
The user lines are optically isolated. The output lines are open collector
configuration. The input lines are capable of sinking 10mA (with recommended
5V at input) up to a maximum 90mA.
The analog program and monitor lines are fully isolated from the supply output,
but not each other. Isolation to chassis is limited to 58 V.
CAUTION
To avoid damage to the power supply, do not apply signals to Analog programming lines
in excess of 58 V wrt chassis, or 12 V wrt Analog programming ground.
Use precision variable low noise voltage sources for the program lines, and be
sure that the program source ground potential is the same as on the analog
readback circuitry.
The external analog monitoring circuitry must be high impedance because the
onboard V and I readback sources have approximately 300 ohms output
impedance.
Connect your program and readback lines to the removable wire clamp connectors
marked “user lines” and “program lines” in Figure 4-1. Strip 0.2” (5mm) of
insulation from the wires and clamp securely at the appropriate pin. See Table 4-1,
Figure 4-1 and Table 4-2 for the location and function of each connector.
Use shielded twisted pairs of 22–24AWG for signal connections.

Remote Operation
Using Remote Analog Control
Connect your programming voltage sources and monitors, ensuring that the
appropriate 0– 5V or 0–10V range has been configured and selected. (See “Select
Remote Control Source” on page 3–19.) With the Analog Control mode selected,
varying the programming source from 0 to 5V (or 10) will vary the output voltage
or current from 0 to its rated maximum. A voltage in the range of 0–5V (or 10) on
the corresponding monitor line is proportional to 0–100% of the rated output.
The output V and I readback lines are active for all operating modes as are the
user interface lines. The analog programming inputs are active only when selected
using the procedure in “Select Remote Control Source” on page 3–19. You can
select analog remote control or either the output voltage or current, or both. When
only voltage or current is being remotely controlled, the other setpoint is under
front panel local control.

Multichannel Operation
Multichannel Operation
Multichannel Connections
You may remotely control up to 50 power supplies from one programming
interface (RS-232 or GPIB) by using multichannel addressing if the CANbus
option is installed.
One power supply will be connected to a PC via RS-232 or GPIB. All other power
supplies are connected via CANbus (Controller Area Network) to that unit. SCPI
commands that include a channel address will be sent via the CANbus to the other
power supplies. (Commands with the local address will be executed locally and
will not be sent).
The multichannel address must be appended to the program mnemonic. If no
multichannel address is appended to the program mnemonic, the command is
executed by the local (directly connected) power supply.
Each unit of the network can send and receive commands to and from other units
on the network. It is highly recommended that only one command be sent at a
time. Any RS-232 and GPIB timeout settings should be increased when using
multichannel commands.
CANbus
The CANbus port is a one male, one female DB9 connector to support “daisy
chain” connections. The CAN (Controller Area Network) is an ISO standard
(ISO11898) for a serial communication network. Table 4-5 describes the pin
functions. Pins 1, 4, 8, and 9 are not used. The CANbus is used for
communications in multichannel operation or current sharing (master/slave)
operation, and is part of the optional GPIB/CANbus interface card.

Configuration
Before connecting a power supply to a multichannel network, you must configure
each power supply with a unique address. The front panel or a remote interface
maybe used to do this.
One power supply must be configured to operate via RS-232 or GPIB.
Front Panel
1. Select the "REMOTE CONFIG" menu
2. Select the "Multichnl Cfg" menu. Press ENTER.
3. When prompted with "Addr" enter a unique network address in the range 1–
50. Press ENTER
To receive and execute commands:
◆ Select the "REMOTE SELECT" menu, then select "Multichannel" from
the list. Press ENTER.
SCPI
Set a slave's multichannel address using the command:
SYSTem:COMMunicate:MCHannel:ADDRess <multichannel-address>
where multichannel-address is an integer in the range of 1-50, and the command is
sent via a controller directly connected to the slave’s RS-232 port.
If the unit is to execute commands, set the power supply to accept control via
multichannel commands (the CANbus interface) with the SCPI command:
SYSTem:REMote:SOURce MCHannel

Multichannel Operation
Setup
1. Connect power supplies to be controlled via the CANbus network. Parallel
male DB9 to female DB9 cables (N-1) are required. Connect the power
supplies in series, linking the first power supply to the second using one cable,
and then the second to the third using a second cable and the second CAN
port. A single ribbon cable with multiple connectors may be used instead of
several cables for ease of connection. Terminate the bus at each end with a
120 ohm, 1/4 Watt resistor (included) across the CAN HI and CAN LO
signals (Pins 2 and 7). See Table 4-5, “CANbus Pins” on page 4–11.
2. At least one power supply should be connected to a PC via RS-232 or GPIB
for multichannel functionality. Configure each of the power supplies with a
unique address, as described in the configuration section. Addresses may be
in the range 1 to 50 inclusive.
3. Turn the power supplies on one at a time, setting the remote control source of
each power supply which will accept commands to "multichannel."

Remote Operation
Using Multichannel Operation
Once the power supplies have been configured and connected, you may power
them on.
Power supplies controlled via multichannel have full capabilities, including
changing REM/LCL modes and calibration.
Any power supply may send multichannel commands, if they are connected to a
PC via RS-232 or GPIB.
A power supply will attempt to connect to the network:
•
•
on power up, and
when the multichannel address is changed.
Note that slave units have an automatic readdressing capability when in
multichannel mode. A slave unit will attempt another address when it is added to a
string with an address that is already taken. If no new address can be found then
the following error will be queued:
Error 1702, “Multichannel address taken”is queued if the
power supply fails to connect.
SCPI Remote Control (RCONtrol) subregister will indicate the status of the
connection. A power supply that has been disabled will not have any bits set. Use
the SCPI command:
STAT:OPER:RCON:COND?
to query the condition of the multichannel interface.
See Table 4-13, “Remote CONtrol Sub-Register” on page 4–49 for a description
of the bits in this register.

Multichannel Operation
Multichannel Commands
To send a command to a multichannel power supply, attach the channel address to
the command. If no channel number is specified, the command will be executed
by the directly connected power supply.
For example, the command:
SOURCE12:VOLT 10.0
will set the power supply with address 12 to 10V output. The master receives the
command and puts in on the CANbus.
Appendix C in your manual lists all commands. [<channel>] indicates where
the multichannel address is to be inserted into the command.
IEEE488.2 commands have been given an alias that is SCPI compliant if the
command is applicable to a power supply in multichannel operation. These
commands include *CLS, *IDN?, *OPT?, *RST, *TST?, *RCL, *SAV, *SDS,
and *WAI. See Table C-9, “System Commands” on page C–19 in your manual.
Important: The multichannel interface may not handle multiline response messages.
Multichannel Broadcast Commands
Add a suffix of "0" to simultaneously broadcast the "command" to the master and
all other units on the CANbus. Only commands are allowed, queries are not
allowed. Note that there will be a lag in execution time between the local unit and
all other units of up to a maximum of 20 ms. For example:
SOURCE0:VOLT 10.0
will set all units in a multichannel string to 10.0 V

Store User Settings
If you have a frequent or constant need for a specific voltage and current output,
you can save these setpoints in the power supply’s memory as a user setting. Once
a setting is stored, it remains in the power supply’s memory after the unit is
powered off.
See “Store User Settings” on page 3–21 for a list of parameters that are saved.
To store (save) settings:
*SAV <user-setting>
Example:
*SAV 1 will save all the present settings to user setting location 1.
To recall settings:
*RCL <user-setting>
To save default settings:
*SDS <user-setting>
This will save factory default settings to a user setting location, replacing any
setting that was previously saved there.
Example:
To save settings, set up the power supply with all required settings (we
recommend that you do this right after recalling the factory default settings).
For example, you can set voltage, current, and all protection levels.
Then to save the settings to Location 1: issue the command *SAV 1
When you want to recall the settings, issue the command *RCL 1. If you want to
recall them at the next power on, issue the command:

Triggering Commands
Triggers are event-driven signals that instruct power supplies to change their
output. Triggering provides a method to control changes in the power supply’s
output and to program several power supplies to react at the same time. Triggering
is useful in manufacturing processes where power requirements change as the
machinery performs different operations.
CAUTION
Setpoint limits do not apply to triggered setpoints.
To program triggers:
1. Configure the desired output levels as a result of a trigger.
VOLTage:TRIGgered {<voltage>|MAX|MIN|DEF}
CURRent:TRIGgered {<current>|MAX|MIN|DEF}
POWer:TRIGgered {<power>|MAX|MIN|DEF}
The user can choose to set all or any one of voltage, current, and power triggered
levels.
DEF (DEFault) means that when a trigger is received, no change will occur.
2. Specify a trigger signal source.
TRIGger:SOURce {BUS|EXT|IMM|NONE} Where:
• BUSmeans the trigger source is the IEEE 488.1 GET or “*TRG”
• EXTmeans the source is the external trigger line
• IMMmeans the trigger source is the SCPI command INIT:IMM
• NONEmeans triggering is disabled. See Figure 4-2, “Schematic For User
Line Interface” on page 4–6.

SCPI Commands for Digital Interfaces
Auto Sequencing
Auto Sequencing allows users to program a sequence of steps. Each step has the
properties of voltage, current, power limits, and OVP limit. The steps are either
programmed to run for a predetermined length of time or are programmed to
pause and wait for a trigger.
CAUTION
Setpoint limits do not apply to auto sequence programmed setpoints.
Programmed sequences can run one time only, or repeatedly up to 9999 times or
infinitely. You can store up to 10 sequences of 99 steps each. The duration of each
step may range from a minimum of 10 milliseconds to a maximum of 99 hours.
Operation
Users can select and start a sequence, and while the sequence is running, pause or
end it. Users can press and hold the TRIGGER button to skip over steps that have
a set duration.
Commands are also available to let users run, pause, resume, and restart an
autosequence. A pause, or wait for trigger, causes the power supply to hold the
output at the programmed level until the appropriate signal to continue is
received.
Editing
Users can delete single steps or entire sequences. If a step is deleted, the
subsequent steps will shift up. If a new step is inserted, the subsequent steps will
shift down.
Remote programming of auto sequences has the same functionality as using the
front panel.

Remote Operation
Programming Sequences
Select Sequence to Program
PROGram:NAME <sequence_number>
<sequence_number>is a number between 1 and 10 that corresponds to the
number of the sequence.
Define the name of the program to be selected. If <sequence_number>
already exists, then that existing program is selected. If the program name does
not exist, then the new name is selected, but no program is defined by this
selection.
Editing the Sequence
To edit an existing step or to program new steps, use the following
commands:
PROG:STEP<step_number>[:EDIT] [[[[[<voltage>]
,<current>],<power>],<OVP_level>],{<time>|TRIG}]
Any of the step parameters may be omitted, in which case the default parameters
will be used. The defaults are 0 V, 0 A, 0 W, 0 V, 10 ms.
To insert a step between commands in an existing program, use this
command:
PROG:STEP<step_number>:INS <voltage>
,<current>,<power>,<OVP_level>,{<time>|TRIG}
The step number is where the inserted step is to be located. The existing step and
all following steps at that location are moved down.
In both the edit and insert commands:
• <step_number>ranges from 1 to 99.
• <time> defines the duration of the step and must be entered in the format
milliseconds. It ranges from 10ms to 99 hours.
• TRIG may be entered instead of a step duration. In this case, the unit will
hold the output levels at that step until a trigger signal is supplied.
Setting Sequence Repetitions
PROG:REP {ONCE |<sequence_count>|FOR|INF}
•
ONCE will run the sequence once and return it to its STOP condition.
• <sequence_count>ranges from 1 to 9999. It will run the sequence the
number of times specified before putting it into the STOP condition.

FORever and INFinity cause the sequence to repeat forever. A query will
return 9.9E37, representing INFinity.
Selecting a Trigger Source
If any triggers are programmed into the sequence, select a trigger source:
PROG:TRIG:SOUR {BUS|MAN|EXT|IMM}
• BUS- trigger signal is IEEE 488.1 GET or *TRG
• MANual- trigger input is from the front panel TRIGGER key
• EXTernal- The external trigger line is selected as the source.
• IMMediate- The source is the SCPI command “INIT:IMM”
Editing Step Parameters
Commands are provided to edit only one of voltage, current, power, OVP level,
step duration, or end action.
Program step voltage:
PROG:STEP<step_number>:VOLT <voltage>
Program step current:
PROG:STEP<step_number>:CURR <current>
Program step power:
PROG:STEP<step_number>:POW <power>
Program step OVP level:
PROG:STEP<step_number>:OVP <OVPlevel>
Program step time (duration):
PROG:STEP<step_number>:DWEL {<time>|TRIG}
To delete a step:
PROGram:STEP<step_number>:DELete
An error will result if the last step with the end action is deleted, without a new
end action programmed to take its place.

Running
PROGram :STATe [RUN|PAUSe|STOP]
•
Once the programmed sequence has been selected, you can start it by setting
the state to RUN, by sending the command PROG:STAT RUN.
•
At any time you can pause the sequence by sending PROG:STAT PAUS.
A paused sequence will cause the supply to hold the output levels at the
setpoints programmed by the current step. To resume, set the state to RUN
again.
•
•
To end the sequence operation, send the command PROG:STAT STOP.
Sending RUN will restart the auto sequence program from the first step.
You can query the state of the selected auto sequence program with
PROG:STAT?
Trigger
If the auto sequence was programmed to wait for a trigger, the power supply holds
the output levels at the programmed setpoints until a trigger is received. It then
advances to the next step. A trigger must come from the selected trigger source.

SCPI Commands for Digital Interfaces
Slew Rate
The slew rate is calculated as a function of change in the output voltage and a
given time interval. The maximum slew rate is 1% V rating/150us. The slew rate
is saved upon power off and restored at power on. Output ON/OFF and shutdown
are not affected by the programmable slew rate. These functions have a slew rate
of 1%/20ms. For more information on setting slew rates, see “Slew Rate” on
page 3–49.
The SCPI commands for changing the voltage slew rate are:
:VOLT:SLEW:STEP {<slewrate-voltage> | MAX | MIN | DEF}
where voltage-step has the units V, mV, etc.
and the range is 0.1% to 5% of rated voltage.
default step is 0.1% of rated output voltage.
:VOLT:SLEW:INTerval {<slewrate-interval> | MAX | MIN | DEF}
where time interval has the units s, ms, or us
and the range is 150 us to 1.5s
default interval is 150us.
CAUTION
Check both the voltage step and the interval to ensure you get the required slew rate.
The combination must not exceed 1% V rating/150us. Though the software will
attempt to achieve higher slew rates, it is limited to this value by hardware
constraints. Manufacturer's recommendation is to keep the slew rate at or below
the default value.
Example:
Set a slew rate of 100V/10s for a 100V-60A power supply.
This slew rate is 1V/0.1s, which is within the acceptable range.
Send the commands:
":VOLT:SLEW:STEP 1",
and
":VOLT:SLEW:INT 100ms"

Option Identification Query
*OPT?
or
SYST[<channel>]:OPTion?
The option identification query returns a string listing any reportable options that
are installed in the power supply. Reportable options are GPIB and CANbus, but
may include others in the future. A zero will be returned if no options are
installed.
Example:
*OPT?may return "GPIB, CANBUS"to indicate that both the GPIB and
CANbus (Multichannel/Current Share) options are installed.
SCPI Version Query
SYST:VERS?
will return the SCPI version to which the unit complies (for example 1997-0).

SCPI Commands for Digital Interfaces
Status Registers
The Status Register structure is mandatory for SCPI and IEEE 488.2 compliance.
The register bits are defined by the SCPI and IEEE 488.2 standards.
Each status register has a Condition, Event, and Enable register and transition
filters. See “Status Register Commands” on page 4–58 for commands to read or
change their values.
Condition
Register
Transitions of the condition register are automatic and reflect the condition of the
instrument at the moment. Reading a condition register has no effect on the
contents.
Event Register
The event register bits are set automatically to correspond with changes in the
condition register. The rules are dependent on the positive and negative transition
registers. Reading an event register clears it. The *CLS command clears all event
registers.
Enable Register
The enable register enables reporting of the event bits to the summary bit or the
status byte. The contents of the enable register are unchanged by *CLS and *RST.
Transition
Filters
A positive transition filter allows an event to be reported when a condition
changes from false to true. Setting both positive and negative filters to TRUE
allows an event to be reported any time the condition changes. Clearing both
filters disables event reporting.
The contents of transition filters are unchanged by *CLS and *RST.
The status registers maybe be divided into 4 categories, the operation status
registers, the questionable status registers, the standard event status register and
the status byte.

OPERation Status Register
The operation status register is a 16-bit register which contains information about
conditions which are part of the power supply’s normal operation.
The Operation Status data structure has the operation status register and 5 sub-
registers to represent regulation, shutdown, protection shutdown, remote control,
and current sharing modes. Each of the sub-registers is summarized in a summary
bit.
Figure 4-4 represents the Operation Status data structure. The “+” represents the
logical summation of bits in a register. Table 4-9, Table 4-10, Table 4-11, Table 4-
13, and Table 4-14 describe the meanings of each bit as well as the bit number and
bit weight.

QUEStionable Status Register
The Questionable Status Register is a 16-bit register that stores information about
questionable events or status during power supply operation. That is, bits in these
registers may indicate that the output of the supply is of undesirable or
questionable quality.
The Questionable Status data structure consists of a questionable status register
and 4 sub-registers representing the status of the voltage, current, power outputs
and temperature.
Figure 4-5 gives an overview of the Questionable Status data structure. The “+”
represents the logical summation of bits in a register. Table 4-15, Table 4-16,
Table 4-17, Table 4-18, and Table 4-19, describe the meanings of each bit as well
as the bit number and bit weight.

Status Register Commands
In the following sections <status-enable> is a value from 0 to 32767 representing
a 15-bit register mask.
SCPI Status Commands
Preset Status
Configures the status data structures to ensure that certain events are reported at a
higher level through the status-reporting mechanism. These events are
summarized in the mandatory structures, the Operation Status Register, and
Questionable Status Register.
The PRESet command affects only the enable registers and the transition filter
registers of the status data structures. PRESet does not clear any of the event
registers or any item from the error/event queue. The *CLS command is used to
clear all event registers and queues in the device status-reporting mechanism.
For the device-dependent status data structures, the PRESet command sets the
enable register to all 1s and the transition filter register to report only positive
transitions. For the SCPI mandatory status data structures, the PRESet command
sets the transition filter registers to recognize only positive transitions and sets the
enable register to 0s. The following will not be affected by this command: Service
Request Enable Register, Parallel Poll Enable Register, the memory register
associated with the *SAV command, the power supply address, Output Queue,
and the power-on-status-clear flag setting.

IEEE 488.2 Status and Event Commands
Clear Status Command
Clears all Event Registers, including the Status Byte, the Standard Event Status
and the Error Queue.
Command: *CLS

STATus[<channel>]:CLEar
Standard Event Status Enable Register
The Event Summary Enable command determines which bits in the Standard
Event Status Register are summarized in the Event Summary Bit (ESB) of the
Status Byte.
The Power-on Status Clear command determines if the Standard Event Status
Enable Register is cleared at power-on.
E.g.
Sending "*ESE 16" sets bit 4 of the Standard Event Status Enable Register. This
will cause the Event Summary bit (ESB) in the Status Byte to be set whenever the
Execution Error bit (bit 4) in the Standard Event Status Register gets set.
Command:
*ESE <status-enable>, *ESE?
SCPI equivalent for multichannel use:
STATus[<channel>]:STANdard:ENABle <status-enable>
STATus[<channel>]:STANdard:ENABle?
Standard Event Status Register
The Standard Event Status Register query allows the user to determine the current
contents of the Standard Event Status Register. (See “Standard Event Status
Register” on page 4–54.) Reading this register clears it.
Command:
*ESR?
SCPI equivalent for multichannel use:
STATus[<channel>]:STANdard[:EVENt]?
Service Request Enable Register
The Service Request Enable Register allows the user to select the reasons for the
power supply to issue a service request. The Service Request Enable Register
allows the user to select which summary messages in the Status Byte Register
may cause service requests.

Remote Operation
To clear the Service Request Enable Register send "*SRE 0." The Power-on
Status Clear command also determines if the Service Request Enable Register is
cleared at power-on. A cleared register does not allow status information to
generate a service request.
E.g.
Sending "*SRE 8" sets bit 3 of the Service Request Enable Register. This will
cause the Summary bit of the Questionable Status register (bit 3) in the Status
Byte to generate a service request message whenever it gets set.
Command:
*SRE <Service-Request-Enable>, *SRE?
SCPI equivalent for multichannel use:
STATus[<channel>]:SREQuest:ENABle <status-enable>
STATus[<channel>]:SREQuest:ENABle?
Parallel Poll Enable Register
Each of the 16 bits in the Parallel Poll Enable register correspond to bits in the
Status Byte. Each bit in the Parallel Poll Enable register is ANDed with its
corresponding bit in the Status Byte and the resulting bits are ORed together to
generate ist. Therefore using the parallel poll enable register allows any single bit
or combination of bits to control the ist message.
The Power-on Status Clear command determines if the Parallel Poll Enable
Register is cleared at power-on.
E.g.
Sending "*PRE 8" sets bit 3 of the Parallel Poll Enable Register. This will cause
the Summary bit of the Questionable Status register (bit 3) in the Status Byte to
generate a TRUE ist message whenever it gets set.
Command:
*PRE <status-enable>, *PRE?
Status Byte
The status byte query will return the contents of the status byte register and the
MSS (Master Summary Status) message. The response is in the format of a
weighted decimal value representing the status byte register and the MSS message
(bit 6). Thus, the response to *STB? is identical to the response to a serial poll
except that the MSS message appears in bit 5 in place of the RQS message. (See
“Status Byte” on page 4–55 for details.)
Command:
*STB?

Power-on Status Clear
The Power-On Status Clear command controls the automatic power-on clearing of
the Service Request Enable Register, the Standard Event Status Enable Register,
the Parallel Poll Enable Register and the Error/Event Queue.
Command:
*PSC {0|1}, *PSC?
SCPI equivalent for multichannel use:
SYSTem[<channel>]:POSClear {ON|OFF|0|1}
SYSTem[<channel>]:POSClear?
Individual Status Query
The individual status query allows the programmer to read the state of the IEEE
488.1 ist (individual status) message without performing a parallel poll. The query
returns a "1" or "0."
The ist message is formed by ANDing the bits in the Parallel Poll Enable Register
(*PRE) with the Status Byte and then ORing the result. In other words, the ist is
TRUE if any of bits of the Parallel Poll Enable Register ANDed with the Status
Byte are TRUE.
Command:
*IST?
Operation Complete
The Operation Complete command causes the power supply to generate the
operation complete message in the Standard Event Status Register when all
pending operations have been finished.
Command:
*OPC, *OPC?
Wait-to-Continue Command
The Wait-to-Continue command prevents the power supply from executing any
further commands or queries until the no-operation-pending flag is TRUE.

Current Sharing
5
Chapter 5 explains what current sharing is, and shows how to
configure and operate units in current sharing mode.
Download from Www.Somanuals.com. All Manuals Search And Download.
Current Sharing
Overview
In many applications multiple power supplies are connected in parallel to supply
large currents to a load. Typically, because of differences in the load wiring and
supply setpoints, each power supply will provide different amounts of current to
the load. Each of the supplies may have to be controlled separately and output
transient response may not be optimal.
6kW and 12kW power supplies equipped with the optional CANbus interface can
be configured to current share using a simple daisy chain control connection
between the units. When configured for current sharing, one supply, configured as
a master, controls the remaining supplies (slaves), via CANbus to equalize the
current drawn from each unit. In addition to balancing the supply outputs, the
current share configuration allows you to control the output voltage, current limit,
and output enable/disable function of all the supplies through the master supply.
You can also choose direct display and readback of the total current from the
system.
Current sharing can be used with a maximum of five supplies of the same model.
Figure 5-1 shows a typical current share system setup.

Setting up Current Sharing
Setting up Current Sharing
To set up multiple supplies for current share operation:
1. Configure each supply with a unique multichannel address. See
“Multichannel Operation” on page 4–11.
2. Configure the supplies for current sharing. Configure one supply to operate as
the master, the others as slaves.
Current sharing may be configured either through the front panel menus or by
SCPI commands sent via a remote interface.
Front Panel
In addition to selecting the current share mode, the master may be set up to
display the summed current from all units.
On the front panel, a MASTER or SLAVE annunciator will light up to indicate the
current share mode.
To configure current share with the front panel:

MEAS:CURR? SUM
The current share subregister (CSHare) will show whether the master or slave is
operating.

See Table 4-14, “Current SHare Sub-Register” on page 4–50 for a description of
the bits in this register.
3. Connect the CANbus ports of all paralleled units and install terminators. See
figure below.
Connect the CANbus ports in series, linking the first power supply to the
second using a parallel male DB9 to female DB9 cable, and then the second to
the third using a second cable, etc. Alternatively a single ribbon cable with
multiple connectors may be used instead of several cables.
Terminate the bus at each end with a 120 ohm, 1/4 Watt resistor (included)
across the CAN HI and CAN LO signals (Pins 2 and 7) as shown below.
Female connector shown. Pinouts are reversed
(left to right) when using a male connector
4. Make load connections.
Connect the output of each power supply to the load or a distribution terminal
which is connected to the load.
To provide reliable current sharing ensure that the lines from each supply are
the same gauge and length.
If you are using remote sense you must:
•
•
Connect the sense lines from all units
Connect all sense lines to the same load sense point.
5. Power up the master.
6. Power up slaves individually.
7. Set the voltage and current limit on the master unit.
Important: Setting the current limit of the master results in the same current limit for
each slave. For example, if five units are connected, setting the current limit of the master
to 10 A may result in a system current of 50 A.
8. Enable the output.

Operation
Operation
Once a current sharing network is setup, you may adjust the voltage and current
limit setpoints on the master. The master will automatically adjust the setpoints of
the slave units to equalize the current output of all units. You may also disable or
enable the output of the master, automatically disabling or enabling the output of
all slaves.
You may use local or remote (RS-232, GPIB, multichannel or analog) control to
operate the master.
Slaves will be operating under remote control from the master and in local
lockout. Hence, they will only respond to remote queries or the OUT ON/OFF key
on the front panel of the master.
The default display will show a greek letter sigma before the readback current if
the summed current output is being displayed. For example, the display may read
"60.00V Σ 500A". However, the setpoint displayed on the master is still the
current limit for a single unit.
The master or slave annunciators will light up and stay on to show that current
share is operating properly.
Power supplies may not enter calibration mode while current sharing, or enter
current share operation while in calibration mode.

Current Sharing
Errors
The master annuciator will flash if it does not detect any slave units on the
network.
The slave annunciator will flash if it does not detect a master on the network.
Check the cable and the master configuration.
A master or slave will be disabled from current sharing (set to "No share") if:
•
•
•
there is more than one master connected to the CANbus, (Error +1911)
there are more than 4 slaves, (Error +1922), or
the model does not match that of the master, (Error +1922).
In each of these cases, the current share mode will be set to "No share".
If a unit becomes disconnected due to a failure in communications, the master will
queue error +1912, "Current Share Slave Lost"and the slave will
queue error +1921, "Current Share Master Lost."The slave's
output will be disabled, and the slave annunciator will flash.
See Table D-13, “Current Share Error Codes” on page D–9 for the list of error
codes and messages.

unit. If you purchased a 12000 Watt unit, please contact your
supplier or Xantrex directly (see “Warranty” for contact
information).

Calibration (6000 Watt only)
Overview
The calibration of the unit is software dependent; there are no potentiometers to
adjust.
Calibration may be performed via the front panel or SCPI commands. Front panel
calibration is partially automated. The calibration points are set automatically and
you will be prompted to enter the measurement data.
There are 10 items that need to be calibrated. Output voltage and output current
are mandatory. If you intend to use the analog programming interface, you must
calibrate it as well. It needs to be calibrated in both the 0-5V and the 0-10V
ranges. In each range, voltage programming, voltage readback, current
programming and current readback need to be calibrated.
All calibration data is taken at 10% and 90% of the rated outputs.
The setting and readback accuracy of the power supply should be checked
annually, and calibration done only if the unit is not operating within its
specification.
Important: POWER is calculated from voltage and current readback.
The OTP and AC off protection mechanisms are operational during calibration.
All other protection mechanisms are disabled.

To set up to calibrate output voltage and current:
Connect a load to the output of the power supply and a current shunt in series.
You will need to use the DVM to measure both the voltage at the output of the
power supply and the voltage across the shunt. You will need to convert the
voltage across the shunt to a current measurement.
To set up to calibrate the analog programming interface, you will need a 0-10V
power supply to provide a programming signal to the voltage and current
programming lines. You will also need to connect the DVM to measure the signal
at the readback lines.

SCPI Command Reference
SCPI Command Hierarchy
SCPI is an ASCII-based command language designed for use in high-technology
test and measurement equipment. The command structure is organized around
common roots, or nodes, which are the building blocks of SCPI subsystems. An
example of a common root is CALibration, and some of the commands that reside
in the CALibration subsystem are shown below.
CALibration
:CURRent
[:DATA] <numeric value>
:LEVel {MIN|MAX}
[:SECure]
:CODE <new code>
:STATe {OFF|ON}, <code>
:STATe?
CALibration is the root keyword of the command. CURRent and SECure are
second-level keywords, and DATA, LEVel, CODE, and STATe, are third-level
keywords. A colon (:) is used to separate a command keyword from a lower-level
keyword.

Using SCPI Commands
Using SCPI Commands
Throughout these commands, the optional command [<channel>]is available
for the units equipped with the optional CANbus interface card.
This manual shows SCPI commands in the following format:
CALibration:CURRent:LEVel {<current>|MIN|MAX}
The command is expressed as a mixture of upper- and lowercase letters. The
uppercase letters suggest how the command can be abbreviated into a short form.
SCPI commands can be sent in long or short forms. The short form is better for
data entry. The long form is better for readability.
Command strings are not case sensitive: CURR, Curr, and curr are all acceptable
abbreviations for CURRent. As for the long form, CURRENT, Current, and
current are all acceptable.
The command strings include punctuation. While some punctuation is sent with
the string, other markings are used to identify different elements of the command
syntax and are not sent with the string.
The following punctuation is sent with the command string:
•
•
•
•
Colons (:) separate command keywords from lower-level keywords.
For example,
CAL:CURR:STAT.
Blank spaces separate command keywords from parameter values.
For example,
CURR 0.1.
Commas separate parameters from each other when more than one parameter
is sent in the same string. For example,
CAL:STAT OFF,”1234.”
Semicolons (;) separate multiple commands from the same subsystem. This
allows for greater efficiency. For example:
CAL:CURR:LEV MIN;VOLT:LEV MIN
is the same as typing:
CAL:CURR:LEV MIN
CAL:VOLT:LEV MIN
•
Colons and semicolons can be used together to link commands from different
subsystems. For example:
CAL:CURR:LEV MIN;:MEAS:CURR?

SCPI Command Reference
The following punctuation is not sent with the command string:
•
Braces ( { } ) identify a selection of choices. Choose one of the enclosed
values.
•
•
Vertical bars, or pipes, ( | ) separate the choices found within the braces.
Angle brackets ( < > ) identify where specific values must be entered for a
parameter. For example, in the example at the top of the page, the parameter
<current> appears in the command string. To set the current setpoint to 0.1A,
the syntax is
CAL:CURR:LEV 0.1.
•
Square brackets ( [ ] ) identify optional parameters. If an optional parameter
is not sent with the command string, a default parameter is sent in its place.
Using Minimum and Maximum
In the following example, Minimum and Maximum are offered as alternative
choices to declaring a specific parameter value.
CAL:CURRent:LEVel {<current>|MIN|MAX}
The string CAL:CURR:LEV MINsets the current calibration level to the
minimum model value.
Using Queries
A question mark lets you query the present value for most parameters. For
example, to query the current calibration state use:
CAL:SEC:STAT?
You can also use the following to query minimum and maximum allowed values
for most parameters:
:VOLT? MIN
:VOLT? MAX
Important: If you send 2 queries, it is best to read and respond to the first response
before trying to read the second. Otherwise, you may receive an incomplete first response
followed by a complete second response. To avoid this, you can either wait for and read
the first response before sending the second query, or send a device clear message before
sending the second query.

Using SCPI Commands
Terminating Characters
Every command string must end with a terminating <new line> character. An
IEEE-488 EOI (end-or-identify) can be used instead of a <new line> character. It
is also acceptable to use a <carriage return> followed by a <new line>.
Terminating a command string always resets the SCPI command path to the root
level.
Common Commands
The IEEE-488.2 standard includes a set of common commands for functions such
as reset and self-test. These common commands always start with an asterisk (*),
contain 4 or 5 characters, and may have one or more parameters. The command is
always separated from the parameter by a blank space. Multiple commands sent in
the same string are separated by a semi-colon (;). The following is an example of
how 3 common commands can be sent together in the same string:
*OPC; *PSC Off; *TRG

SCPI Command Reference
Parameter Types
Several different data types are defined for use in program messages and response
messages.
Boolean
Parameters
Boolean parameters are single binary conditions such as 1 and 0, or ON and OFF.
The following is an example of a command that uses Boolean parameters:
SYST:COMM:GPIB:PONS {ON|OFF|1|0}
Discrete
Parameters
Discrete parameters are used when program settings have a limited number of
values. If you query a discrete parameter, the response will always be in the short
form with all uppercase letters. The following is an example of a command that
uses discrete parameters:
TRIG:SOUR {BUS|EXT|IMM|NONE}
Numeric
Parameters
Numeric parameters are number representations such as decimal points, optional
signs, and scientific notation. Values such as MINimum and MAXimum are
accepted as substitutes for numbers. When DEFault is provided as a parameter,
the machine selects the default value automatically. You can also use engineering
unit suffixes such as, V, A, or W with numeric parameters. In cases where specific
numeric values are accepted, the power unit will round the input parameters. The
following is an example of a command that uses numeric parameters:
VOLT:PROT {<voltage>|MAX|MIN}
String
Parameters
String parameters are used when a series of ASCII characters is required. Strings
must be enclosed within single or double quotations. The beginning and ending
quotation marks must be matching. Quote delimiters may be included in the string
by typing the quotation marks twice without any characters in between. The
following is an example of a command that uses string parameters:
CAL:STAT ON, “0000”

Notes:
All legacy commands that change a value conform to the same rules as SCPI. Commands will cause an
error if the unit’s remote source, remote state, current share mode status and calibration status is
incorrect.
Legacy commands do not have multichannel capabilities.
Query commands return a string containing the command itself.
The “CLR” command does not clear any legacy fault registers.
The “RST” command only clears the protections so that the voltage and setpoints can take effect. It
does not change any setpoint values. When a protection is tripped the unit’s output may be turned off
(configurable).
