The TekConnect Interface
Power for the 80A03 TekConnect Probe Interface Module, sampling module, and
TekConnect probes is supplied through the cable that connects the TekConnect
Probe Interface Module to the sampling oscilloscope. The same cable also
provides a data and communications path from the probe contact pins through
the interface to the oscilloscope. Power, signal, offset, and probe characteristic
data transfers through this interface.
When a probe is connected, the TekConnect Probe Interface Module reads
information from the probe, identifies the device, and turns on the appropriate
power supplies.

Operating Basics
Triggering the Sampling Oscilloscope
Use the following procedures to set up the 80A03 TekConnect Probe Interface
Module to trigger and view signals on CSA8000 and TDS8000 Series sampling
oscilloscopes.
Trigger Bandwidth
Considerations
The TekConnect Probe Interface Module supports many models of TekConnect
probes. Since the trigger bandwidth limit is determined by the probe bandwidth
and oscilloscope trigger capability, some probes may be more suitable than
others to your measurement needs.
CSA8000 and TDS8000 Series oscilloscopes provide two trigger inputs you can
use with external probes, direct or prescaled. When selecting an input, you
should consider the frequency of the signal being measured. The bandwidth
specification of the measurement probe must also meet or exceed that of the
signal being measured.
In addition, consider the following factors when setting up equipment to take
measurements:
H
The oscilloscope trigger sensitivity relative to the amplitude of the signal
being measured.
H
H
The probe scale factor.
The attenuation factor of the power divider used, if you choose to view
signals on the oscilloscope following the trigger.
NOTE. Refer to your sampling oscilloscope documentation for direct and
prescaled trigger specifications.

You can view probe characteristics in the system properties menu for the
measurement channel.
If you use the sampling oscilloscope Trigger Direct input, it is recommended that
you set the trigger level on the oscilloscope to 0 volts and control the trigger
level by directly assigning the vertical offset for the probe at the probe tip.
Because the offset control in the probe affects the signal level at its output, this
method of vertical offset adjustment provides calibrated trigger level operation.
To operate the offset control as a trigger level adjustment, rotate the offset adjust
on CH B. This will control the offset at the probe tip so you can read the trigger
level directly from the offset indicator on the sampling oscilloscope. See
Figure 10.

NOTE. Rotation of the control knob for this configuration is reversed. Clockwise
rotation introduces a negative offset adjustment, which provides a negative
trigger level. Counterclockwise rotation introduces a positive offset and a
positive trigger level.

errors.
If you use the sampling oscilloscope Trigger Direct input, it is recommended that
you set the trigger level on the oscilloscope to 0 volts.
With this configuration, you can control the trigger level by directly assigning

in the probe affects the signal level at its output, this method of vertical offset
adjustment provides calibrated trigger level operation.
To operate the offset control as a trigger level adjustment, rotate the offset
adjustment on the sampling module channel that has the probe output discon-
nected. This will control the offset at the probe tip and you can read the trigger
level directly from the offset indicator on the sampling oscilloscope, as shown in
Figure 10.
NOTE. The 2X power divider used in this setup introduces a vertical scale error
factor of 2.

Reference
This section contains information you may need to take measurements or to
avoid damaging the 80A03 TekConnect Probe Interface Module.
Avoiding Damage from Overvoltage
Know your signal source. If it is capable of delivering overvoltages, it is safer to
not depend on the signal source settings for protection, but instead use an
external attenuator that protects the input from the worst-case conditions. For
example, for a 20 V maximum source connected to a 3 V maximum sampling
module, use a 10X attenuator. Where possible, connect your cables to the signal
source first, and to the sampling module second.
You can use a Tektronix 80A02 EOS/ESD Protection Module to protect the
sensitive input stage of sampling module from damage due to electro-overstress
(EOS) and electro-static discharge (ESD) from the device under test (DUT). Use
the 80A02 in applications such as TDR circuit-board testing and cable testing
where large static charges can be stored on the device under test.
Install the 80A02 EOS/ESD Protection Module between the device under test
(DUT) and the sampling module. When used with the P8018 TDR probe, the
80A02 achieves static protection using normal probing procedures — no
intentional user intervention (such as stepping on a foot switch) is required. This
eliminates instrument damage due to human error in coordinating probing with
control switching to achieve static protection.
Avoiding Damage from Electrostatic Discharge
Circuitry in the sampling module is very susceptible to damage from electrostat-
ic discharge or from overdrive signals. Be sure to only operate the sampling
module in a static-controlled environment. Be sure to discharge to ground any
electrostatic charge that may be present on the center and outer connectors of
cables before attaching the cable to the sampling module.

Reference
CAUTION. To prevent damage from electrostatic discharge, install 50 Ω
terminations (Tektronix part number 015-1022-xx) on the sampling-module
connectors before removing the sampling modules from an instrument or when it
is not in use. Store the sampling module in a static-free container, such as the
shipping container. Whenever you move the sampling module from one instru-
ment to another, use a static-free container to transport the sampling module
To prevent damage to the sampling module, discharge to ground any electrostat-
ic charge that may be present on the center and outer conductors of cables
before attaching the cable to the sampling module.
To prevent damage to the sampling module, do not create an ESD antenna by
leaving cables attached to the sampling-module input with the other end of the
cable open.
To prevent damage to the sampling module or instrument, never install or
remove a sampling module when the instrument is powered-on.
Always use a wrist strap (provided with your instrument) when handling
sampling modules or making signal connections. Wear anti-static clothing and
work in a static-free workstation when using sampling modules.
