80A03 TekConnect Probe Interface Module Instruction Manual 1
Getting Started
The 80A03 TekConnect Probe Interface Module is an adapter that allows you to
use TekConnect probes with 80E0X sampling modules and the following main
instruments (mainframes):
HDSA8200 Digital Serial Analyzer
HCSA8000, CSA8000B, and CSA8200 Communications Signal Analyzers
HTDS8000, TDS8000B, and TDS8200 Digital Sampling Oscilloscopes
The interface is comprised of an enclosure that houses a compartment for one
80E0X electrical sampling module and two TekConnect probe inputs. The
interface connects to the mainframe through a permanently attached 1 meter
extender cable.
Figure 1: The 80A03 TekConnect Probe Interface Module
The 80A03 TekConnect Probe Interface Module also allows you the flexibility of
using the interface as a general-purpose sampling module extender cable by
simply disconnecting the short semi-rigid cables on the front panel of the
interface and using the sampling module inputs directly.

Getting Started
280A03 TekConnect Probe Interface Module Instruction Manual

The following electrical sampling modules are recommended for use with the
TekConnect Probe Interface Module.
Supported Tektronix
sampling modules
Description
80E011Single channel, 50 GHz
80E022Dual channel, 12.5 GHz
80E032Dual channel, 20 GHz
80E042Dual Channel, 20 GHz with TDR
80E061Single channel, 70 GHz
1Requires 2.4/1.85 mm to 2.92 mm SMA adapter (Tektronix part number 011- 0157- 00,
standard with these sampling modules). Also requires custom cable not available
from Tektronix: use a short high-quality SMA cable or fabricate your own semi-rigid
cable. Bandwidth using these modules is limited by the 80A03 adapter.
2Recommended for use with 80A03 TekConnect Probe Interface Module.

Getting Started
80A03 TekConnect Probe Interface Module Instruction Manual 3
The 80A03 disables the Probe Power interface on the front of the sampling
modules. Do not use the 80A03 with probes that connect directly to the Probe
Power, such as the P6209 and P6207.
There is also no support for TekProbe Level 2 legacy probes that utilize the
TCA-1MEG, TCA-BNC, and TCA75 adapters.
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 your mainframe. The same cable also provides a data
and communications path from the probe contact pins through the interface to
the mainframe. 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.
Standard Accessories
Table 1 lists the 80A03 TekConnect Probe Interface Module features and
standard accessories.

2. Installing the Sampling Module.
3. Installing the Semi-Rigid SMA Connector Cables.
4. Installing the TekConnect Probe.

Getting Started
80A03 TekConnect Probe Interface Module Instruction Manual 5
To install the TekConnect Probe Interface Module Extender Cable into the front
panel of your mainframe, perform the following tasks:
CAUTION. To prevent damage to the sampling module, never install or remove a
module when the mainframe is powered on or when either input connector is left
unprotected. Follow the precautions described in your sampling module and
mainframe documentation to avoid damage.
1. Turn off the mainframe using the front-panel On/Standby switch.
2. Install the TekConnect Probe Interface Module Extender Cable connector
into any of the small sampling module compartments on the front panel of
the mainframe. See Figure 3.
3. Push the module in slowly with firm pressure to seat it.
4. Tighten the hold-down screw to hold the connector in place. To remove the
connector later, loosen the hold-down screw and slide the ejector lever.
NOTE. Installing a large sampling module into a large compartment of the
mainframe may disable channels on a small module already installed. Refer to
the documentation for your mainframe about compartment interaction.

To install the sampling module into the front panel of the TekConnect Probe
Interface Module, perform the following tasks:
CAUTION. Sampling modules are inherently vulnerable to static damage. Always
observe static-safe procedures and precautions as outlined in your sampling
module user manual.
1. Verify that the mainframe is powered off; if necessary, toggle the front-panel
On/Standby switch.
2. Insert the sampling module into the front-panel compartment of the
TekConnect Probe Interface Module as shown in Figure 4.
3. Push the module in slowly with firm pressure to seat it.
4. Once the module is seated, turn the hold-down screw to tighten the sampling
module in place. See Figure 4.
5. To release the module later, loosen the hold-down screw fully, and then slide
the ejector lever.

80A03 TekConnect Probe Interface Module Instruction Manual 7
To provide a signal path between the sampling module and the TekConnect
Probe Interface Module, perform the following tasks:
1. Connect your wrist strap to the antistatic connector on the front of the
mainframe.
2. Use the two semi-rigid SMA cables (included with this product) to connect
the TekConnect Probe Interface Module to the sampling module as shown in
Figure 5. You may need to bend the SMA cables slightly to obtain proper
alignment to mate the SMA connectors.
NOTE. Always use a calibrated torque wrench to install adapters, attenuators,
cables, or power sensors in any setup. Torque all connections to 8 ±0.3 inch
pounds. For information on proper installation and torquing techniques, refer to
your module user manual.
Figure 5: Connecting the sampling module
CAUTION. The semi-rigid SMA connector cables used on the 80A03 TekConnect
Probe Interface Module are not compatible with the input connections of
80E01and 80E06 sampling modules.
Do not attempt to force a connection between the semi-rigid connector cables on
the TekConnect Probe Interface Module and these sampling modules. Use the
proper adapter or damage to the module will occur. See page 2 for additional
information.

The TekConnect probe features a spring-loaded latch that provides audible and
tactile confirmation that a reliable connection has been made to the TekConnect
Probe Interface Module.
NOTE. It is not necessary to power off the mainframe when removing or
installing a TekConnect probe.
To connect a TekConnect probe to the TekConnect Probe Interface Module,
perform the following tasks:
1. Slide the probe into the TekConnect receptacle on the TekConnect Probe
Interface Module. The probe snaps into the TekConnect Probe Interface
