SAFETY SUMMARY
The following general safety precautions must be observed during all phases of operation, service, and repair of this
mainframe. Failure to comply with these precautions or with specific warnings elsewhere in this guide violates safety
standards of design, manufacture, and intended use of the mainframe. Agilent Technologies assumes no liability for the
customer’s failure to comply with these requirements.
BEFORE APPLYING POWER.
Verify that the product is set to match the available line voltage and the correct fuse is installed.
GROUND THE MAINFRAME.
This product is a Safety Class 1 instrument (provided with a protective earth terminal). To minimize shock hazard, the mainframe must
be connected to an electrical ground. The mainframe must be connected to the ac power supply mains through a three-conductor power
cable, with the third wire firmly connected to an electrical ground (safety ground) at the power outlet. Any interruption of the protective
(grounding) conductor or disconnection of the protective earth terminal will cause a potential shock hazard that could result in personal
injury.
DO NOT OPERATE IN AN EXPLOSIVE ATMOSPHERE.
Do not operate the instrument in the presence of flammable gases or fumes.
KEEP AWAY FROM LIVE CIRCUITS.
Operating personnel must not remove instrument covers. Component replacement and internal adjustments must be made by qualified
service personnel. Do not replace components with power cable connected. Under certain conditions, dangerous voltages may exist even
with the power cable removed. To avoid injuries, always disconnect power, discharge circuits and remove external voltage sources before
touching components.
DO NOT SERVICE OR ADJUST ALONE.
Do not attempt internal service or adjustment unless another person, capable of rendering first aid and resuscitation, is present.
DO NOT EXCEED INPUT RATINGS.
This mainframe is equipped with a power line filter to reduce electromagnetic interference and must be connected to a properly grounded
receptacle to minimize electric shock hazard. Operation at line voltages or frequencies in excess of those stated on the line rating label
may cause leakage currents in excess of 5.0 mA peak.

Mainframe Installation Guide
Description
The Agilent 66000 Modular Power System (MPS) is an integrated, fully programmable power system that saves rack space
and GPIB addresses, and is easy to install and use. Each Agilent 66000A MPS Mainframe can accommodate up to eight
single-slot modules. With an auxiliary mainframe connected through a serial link cable, up to sixteen single-slot modules
can be controlled from a single GPIB address. For applications requiring a broader range of power ratings, the Agilent
66000 system can be serial-linked to the Agilent 667xA, 665xA, 664xA, and 603xA series power supplies.
Modules are removed and installed through the front of the mainframe. Each module has a connector that attaches to the
back of the mainframe. With the module connector wired and attached to the mainframe, the module slides in and out of the
mainframe without disturbing the application connections.
The optional Agilent 66001A MPS Keyboard is available for controlling the Agilent 66000 Modular Power System without
having to connect it to a computer.

Frame Mode Switch
The frame mode switch determines the IEEE 488 secondary addresses (also referred to as subaddresses) of the modules that
are installed in the mainframe. The frame mode switch must be set to MAIN when the mainframe is connected directly to
the GPIB. With the frame mode switch set to MAIN, modules are assigned secondary addresses of 0 to 7, which
corresponds to the slot locations indicated on the mainframe.
The frame mode switch must be set to AUX (auxiliary) when the mainframe is serially-linked to another mainframe that is
directly connected to the GPIB. This also applies when the mainframe is serially linked to an Agilent 603xA/664xA/665xA/
667xA power supply that is directly connected to the GPIB.
In mainframes that have the frame mode switch set to AUX, modules are assigned secondary addresses of 8 to 15.
Secondary address 8 corresponds to slot location 0 on the mainframe and secondary address 15 corresponds to slot location
7 on the mainframe as shown in the following diagram.

Secondary addresses are reserved for the mainframe whether modules occupy the associated slot locations
or not.
You may want to apply stick-on labels over the slot locations of the mainframe to indicate that the modules installed in the
auxiliary mainframe are at secondary addresses 8 to 15. You may also label the modules according to their slot locations.
If any modules are removed, they can then be reinstalled in the same slot.
Figure 2-4 illustrates the relationship of the switch settings and secondary addresses. Refer to Chapter 3 for connection
information.

If the module is not fully inserted in the mainframe, the pull tab will not retract into the module.
■
■
Install filler panels in the front of any unused mainframe slots.
Install the module connectors on the back of the mainframe.
Note
Instructions for wiring and installing module connectors are included with each module.

Module Removal
All modules are removed through the front of the mainframe. Modules may be removed even when the mainframe is turned
on.

Installation
■
■
There must be no or minimal current flowing through the connector pins at the back of the module
that is being removed. This can be accomplished by disabling the module. If this precaution is
repeatedly violated at high current, the connector pins at the back of the module
will be damaged.
There must be no activity on the GPIB bus, the trigger connectors, or the FLT/INH connector of
the mainframe when a module is removed. This can be accomplished by not generating any GPIB
or FLT/INH activity, and by setting all modules to the trigger idle state (refer to the module
Programming Guide). If this precaution is violated, GPIB commands to other modules may be
corrupted, trigger or FLT/INH data may be lost, or an inadvertent trigger may be generated in
another module.
To remove the module from the mainframe, proceed as follows:
■
■
Use a flat-bladed screwdriver and release the pull tab by pressing down (see Figure 2-5).
Grasp the pull tab and pull the module out of the mainframe.
Note
The module connector remains attached to the mainframe after the module has been removed.
Mainframe Turn-On Checkout
The turn-on checkout procedures that verify module operation also verify the operation of the MPS mainframe. You cannot
verify the operation of the mainframe without having at least one installed module. The module self-test sequence checks
the following mainframe functions:
■
■
■
mainframe microprocessor
GPIB interface
module/mainframe communications link
Refer to the module User’s Guidefor complete information on the turn-on checkout procedure.

Connections
Rear Panel
Figure 3-1 shows where all of the rear panel connections to the mainframe are made.
Figure 3-1. Rear Panel Connections
Module Connections
Wire connections to the modules are made using a separate module connector that is supplied with each module. After the
module connector has been wired, it simply attaches to the back of the mainframe. You can attach the module connector to
the mainframe either before or after the module is installed. Instructions for wiring and attaching the connector are provided
with each module.
Note
Install the module connectors from left to right on the back of the mainframe. This makes it easier to
access the screws that attach the connectors to the mainframe.

Connections
Controller Connections
If you have only one MPS mainframe in your system, simply connect it to the controller using the GPIB cable. If you have
more than one mainframe, or if you also have an Agilent 667xA, 665xA, 664xA, or 603xA power supply in your system,
you can use the serial-link cable supplied with your mainframe to facilitate connections. Figure 3-2 illustrates the serial-link
connections.
Multiple MPS Mainframes
See Figure 3-2. Up to 16 modules may be controlled from a primary GPIB bus address by linking two mainframes.
■
■
The first mainframe in a linked configuration is directly connected to the controller via a GPIB cable. The frame mode
switch on the back of this mainframe is set to "MAIN". The first mainframe has a unique primary GPIB address and
the modules in this mainframe use secondary addresses (also referred to as subaddresses) 0 through 7.
The second or "linked" mainframe, connects to the first mainframe with the serial-link cable. The frame mode switch
on the back of this mainframe is set to "AUX". The second mainframe uses the same primary address as the first
mainframe, but the modules in the second mainframe use secondary addresses 8 through 15.
MPS Mainframe/Power Supply Connections
See Figure 3-2b. Only one mainframe can be serially linked to a system that includes Agilent 667xA, 665xA, 664xA, or
603xA power supplies. Because the mainframe has only one serial-link jack, it can be either linked at the beginning or at
the end of a power supply serial link system.
■
■
At the beginning of the serial link system, the mainframe is directly connected to the controller via the GPIB cable.
The frame mode switch on the back of this mainframe is set to "MAIN". The mainframe has a unique primary GPIB
address and the modules in this mainframe use secondary addresses (also referred to as subaddresses) 0 through 7. All
power supplies serially linked to the mainframe use the same primary GPIB address, but must use secondary addresses
8 through 15.
At the end of the serial link system, the mainframe is linked to the last power supply in the system with the serial-link
cable. The frame mode switch on the back of this mainframe is set to "AUX". The mainframe uses the same primary
GPIB address as the power supplies and the modules in this mainframe use secondary addresses 8 through 15. In this
configuration, you can have up to eight power supplies at secondary addresses 0 through 7 ahead of the mainframe.
Keyboard Connection
The optional Agilent 66001A MPS Keyboard connects to the mainframe through the keyboard jack located at the front of
the mainframe and at the back of the mainframe as shown in Figure 3-1. More information on using the keyboard can be
found in the module User’s Guide.
Digital Connections
A 4-pin connector and a quick-disconnect mating plug provide a discrete fault indicator (FLT) output and a remote inhibit
(INH) input (see Figure 3-3). Disconnect the mating plug to make your wire connections. The electrical characteristics of
the FLT output and the INH input are described in Chapter 1. More information on using digital connectors can be found in
Chapter 4 of the module User’s Guideunder "RI Function" and "DFI Function".

FLT Output
(pins 1 and 2)
Used to indicate that a fault has occurred on one of the modules in the mainframe. Pins 1 and 2
are the open-collector output of an optocoupler, with pin 1 the collector and pin 2 the emitter. When a
fault has occurred, pin 1 is driven low with respect to pin 2 (negative-true).
INH Input
(pin 3)
Used to shut down the outputs of all modules in the mainframe that have been enabled to respond to
the remote inhibit function. Pin 3 is a high impedance input. The inhibit function is activated when this
input is driven low (negative-true). This can be accomplished by shorting pin 3 to pin 4.
INH Common
Provides the common connection for the INH input.
(pin 4)
After you have finished making all wire connections, replace the mating plug in the connector.
Figure 3-4 shows two simple applications for the INH input. The first is a "panic switch" that applies the INH input signal
to both mainframes, which shuts down the modules simultaneously in both mainframes. The second application uses the
INH input signal to shut down modules in the main mainframe. In this case, the modules in the main mainframe must be
programmed to generate an FLT signal upon receipt of the INH signal. The FLT signal generated by the modules in the
main mainframe is then applied to the RI input of the auxiliary mainframe.
Note
Software control of the RI function is described further in Chapter 5 of the module Programming Guide.
Trigger Connections
Trigger connections are made to the BNC connectors on the rear panel as shown in Figure 3-1. The electrical
characteristics of the trigger connectors are described in Chapter 1. More information on the capabilities of the external
triggers can be found in Chapter 5 of the module Programming Guide.
Trigger IN
Allows negative-going external trigger signals to trigger one or more modules in the mainframe.
Trigger OUT
Provides a negative-going wired-ORed pulse that indicates a trigger has occurred on one or more of the
modules in the mainframe.
