Getting Started
The Tektronix 80E01, 80E02, 80E03, 80E04, and 80E06 sampling modules are
high-performance sampling modules that can be installed in the following main
instruments:
H DSA8200 Digital Serial Analyzer
H CSA8000, CSA800B, and CSA8200 Communications Signal Analyzers
H TDS8000, TDS8000B, and TDS8200 Digital Sampling Oscilloscopes
Proper operation of the electrical sampling modules requires that the appropriate
application software is installed on the main instrument. In Table 1, each new
release of software supports the additional electrical modules as well as all
electrical modules supported by earlier software versions.
To display the version installed, select About from the Help menu of the main
instrument.

Because the 2.4 mm connector of this adapter will mechanically interface with the 1.85 mm connector of the 80E06, it
serves as a 1.85 mm-to-2.92 mm adapter for the 80E06 module.
As shown in Figure 1, the sampling modules have two independent channels
(80E01 and 80E06 each have one channel), each with its own acquisition
circuitry.
The strobe drive signal from the instrument controls the timing of the strobe
assertion to each acquisition system and guarantees sampling coincidence
between the channels in a sampling module.
CAUTION. To prevent electrostatic damage to the main instrument and sampling
modules, follow the precautions described in this manual and the manuals
accompanying your instrument. (See Electrostatic Discharge on page 6. )

An extender cable extends the reach of a sampling module. You install the extender
between the sampling module and the instrument, allowing you to operate the
sampling module out of the module compartment. If you compensate a module in
the main instrument and then move the module to an extender, or visa versa,
re-compensate the module (for more information see Compensation on page 9).

At least one sampling module must be installed in an instrument to sample
signals.
NOTE. Installing a large module in the left-most slot disables the left-most small
module compartment. Installing a large module in the right-most slot disables
the small module compartment that is second from the left.
Each instrument supports four large-compartment channels, two per sampling
module, and eight small-compartment channels, two per sampling module. Eight
of the ten channels are usable at one time.
Electrostatic Discharge
6
To prevent electrostatic damage to the main instrument and sampling modules,
follow the precautions described in this manual and the manuals that come with
your instrument.
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.
80E00 Electrical Sampling Modules User Manual
Getting Started
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.
CAUTION. To prevent damage from electrostatic discharge, install 50 Ω
terminations on the sampling-module connectors before removing a sampling
module 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 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.
Static Controlled
Workstation
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.
Use a Tektronix 80A02 EOS/ESD Protection Module if doing TDR work.
T o prevent damage to the sampling module or instrument, do not apply a voltage
outside the Maximum Input Voltage (see page 48) for your sampling module.
For information on creating a static-controlled workstation, consult the Electronic Industries Association document EIA-625; Requirements for Handling
Electrostatic-Discharge-Sensitive (ESDS) Devices.
You can use a Tektronix 80A02 EOS/ESD Protection Module to protect the
sampling module from damage due to static discharge from circuit boards and
cables. Use the 80A02 in applications where large static charges can be stored on
the device under test, such as when testing TDR circuit boards or cables.
Refer to the documentation supplied with the 80A02 module for proper
installation and use.

Getting Started
Module Installation
To install a sampling module, first turn off the instrument using the front-panel
On/Standby switch. Then place the sampling module in a compartment and
slowly push it in with firm pressure. Once the sampling module is seated, turn
the hold-down screw on the sampling module to tighten the sampling module
into place. See Figure 4.
CAUTION. To prevent damage to the sampling module or instrument, never install
or remove a sampling module when the instrument is powered on or when either
input connector is unprotected.
NOTE. When removing your sampling module, first loosen the hold-down screw,
and then use the sampling module ejector on the main instrument to eject the
sampling module.

Compensation
After installing a sampling module or after moving a sampling module from one
compartment to another, you should run compensation from the Utilities menu to
ensure the instrument meets it specifications. Also run a compensation (accessed
from the Utilities menu) when doing the following:
H Installing an 80E00 sampling-module extender between the instrument and
an 80E00 sampling module, where none was used before.
H Removing an 80E00 sampling-module extender between the instrument and
an 80E00 sampling module, where one had been used before.
H Exchanging an extender for one of a different length.
For instructions on running a compensation, see Optimizing Measurement
Accuracy in the Online Help for your main instrument.
