80A03 TekConnect Probe Interface Module Instruction Manual
Operating Basics
This section contains information you need to operate the 80A03 TekConnect
Probe Interface Module.
Understanding the Controls
The 80A03 TekConnect Probe Interface Module front panel has one multi-color
LED for each channel. During power on and normal operation, the LEDs report
red, green, or off as explained below. The TekConnect Probe Interface Module
contains no additional user controls.
H Red. Indicates that an incompatible probe is attached to the TekConnect
input. See page 2 for a list of compatible probes.
H Green. Indicates that a supported probe is attached to the TekConnect input.
H Off. Indicates that the probe interface is disconnected from the mainframe
(no power) or that no probe is attached to the TekConnect input.
Power On Status
Probe Status
The following describes typical TekConnect Probe Interface Module operation
when you power on the mainframe with the probe interface installed:
H Both LEDs flicker green, then red, then green, and turn off. This indicates
that proper power is applied and initialization has occurred.
H The LEDs do not light. This indicates that the probe interface is not
receiving power and may be disconnected from the mainframe.
The following describes typical TekConnect Probe Interface Module operation
when you attach a TekConnect probe:
H The LED turns green, indicating that a valid probe is attached. If you pressed
the mainframe channel button, the display also becomes active for the
channel selected.
H The LED turns red, indicating that an invalid or unrecognized probe is
attached.
H The LED remains off, indicating that no probe is detected.
80A03 TekConnect Probe Interface Module Instruction Manual
13
Operating Basics
Triggering the Mainframe
Use the following procedures to set up the 80A03 TekConnect Probe Interface
Module to trigger and view signals on your mainframe.
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 mainframe trigger capability, some probes may be more suitable than others
to your measurement needs.
Your mainframe provides 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 mainframe trigger sensitivity relative to the amplitude of the signal
being measured.
H The probe scale factor.
H The attenuation factor of the power divider used, if you choose to view
signals on the mainframe following the trigger.
NOTE. Refer to your mainframe documentation for direct and prescaled trigger
specifications.

Operating Basics
H You can view probe characteristics in the system properties menu for the
measurement channel.
If you use the mainframe Trigger Direct input, it is recommended that you set the
trigger level 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 mainframe. See Figure 10.
Figure 10: Trigger offset indicator
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.

Operating Basics
Triggering and Viewing
Signals on the Mainframe
To set up the TekConnect Probe Interface Module to trigger your mainframe, do
the following:
1. Remove the semi-rigid cable that connects the CH B TekConnect Probe
Interface Module to the sampling module. See Figure 8 on page 15.
2. Use a 0.5 m SMA cable to connect the 6 dB (2X) power divider to the
disconnected CH B SMA connector on the TekConnect Probe Interface
Module. See Figure 11.
3. Use a 0.5 m SMA cable to connect the disconnected port on the sampling
module to one side of the 6 dB (2X) power divider. See Figure 11.
4. Use a 0.5 m SMA cable to connect the other side of the power divider to the
mainframe trigger input (Trigger Direct or Trigger Prescaled).
5. Attach a TekConnect trigger probe to CH B on the TekConnect Probe
Interface Module. See Figure 11.

Operating Basics
NOTE. Do not connect any other accessory to the mainframe Trigger Probe
power port. Doing so may cause confusion that can lead to measurement errors.
If you use the mainframe Trigger Direct input, it is recommended that you set the
trigger level to 0 volts.
With this configuration, you can control the trigger level by directly assigning
the vertical offset for the CH B 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
adjustment on the sampling module channel that has the probe output disconnected. This will control the offset at the probe tip and you can read the trigger
level directly from the offset indicator on the mainframe, as shown in Figure 10.
NOTE. The 2X power divider used in this setup introduces a vertical scale error
factor of 2.
Sampling Module Incompatibility
Due to SMA cable incompatibility, you cannot directly use 80E01 or 80E06
sampling modules with the 80A03 TekConnect Probe Interface Module. See
page 2 for additional information.

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 electrostatic 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.
80A03 TekConnect Probe Interface Module Instruction Manual
21
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 a main instrument
(mainframe) 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 instrument to another, use a static-free container to transport
the sampling module.
T o prevent damage to the sampling module, discharge to ground any electrostatic charge that may be present on the center and outer conductors of cables
before attaching the cable to the sampling module.
T o 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.
T o 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.

No Signal Detected
If you encounter problems installing or operating the TekConnect Probe Interface
Module, try the following troubleshooting procedures.
To verify that the interface module and microcontroller are functioning properly,
perform the following steps:
1. Attach a valid probe to the TekConnect input:
The LED turns green if the interface module is receiving power and the
microcontroller is functioning normally.
2. Attach an invalid probe to the TekConnect input:
The LED turns red if the interface module is receiving power, the microcontroller is functioning normally, and a probe is being sensed.
If the LEDs respond normally at power on, but no signal is detected by the
