Getting Started
The Tektronix 80E07, 80E08, 80E09, and 80E10 remote sampling modules are
high-performance sampling modules that can be installed in the following
instruments:
H DSA8200 Digital Serial Analyzer
H CSA8000, CSA800B, and CSA8200 Communications Signal Analyzers

Refer to the specification section for complete details on risetime, bandwidth, and noise.
The 80E07, 80E08, 80E09, and 80E10 remote sampling modules have two
independent channels, each with its own acquisition circuitry.
The strobe drive signal from the instrument controls the timing of the strobe
assertion to each acquisition system. This guarantees sampling coincidence
between the two channels of a sampling module.

Getting Started
Installation
The sampling modules fit into the front panel of any of the main instruments
listed Getting Started on page 1.
To install a module, first turn off the instrument using the front-panel On/Standby switch. Then place the module in a compartment and slowly push it in with
firm pressure. Once seated, turn the hold-down screw to tighten the module into
place. See Figure 3.
CAUTION. To prevent damage to the module or instrument, never install or
remove a module when the instrument is on or when input connectors are
unprotected.
NOTE. When removing your sampling module, first loosen the hold-down screw,
and then use the module ejector on the main instrument to eject the module.

Getting Started
NOTE. Refer to the Quick Start User manual for your instrument about the
interaction between large and small module compartments.
Using the Guide Rails
UsingtheEndPlate
Mounting Holes
The guide rails allows you to create a stable environment for the remote
modules. One guide rail is provided for each remote module.
Attach the guide rail to a fixture (or desktop) using the two mounting screws
(provided). The holes in the fixture must have 4--40 threaded holes spaced
1.25 inches (31.8 mm) apart (measured from center of hole).
Once you’ve secured the guide rail to a surface, slide the remote module onto the
rail, engaging the tracks on the bottom of the remote module.
NOTE. The tracks on the remote module and guide rails must be properly mated
to ensure a firm attachment. One track on the module is larger than the other.
The larger track must engage the ball plungers on the guide rail. See the detail
in Figure 4.
The end plate mounting holes also allow you to create a stable environment for
the remote modules. There is one hole in each module end plate: one in the front
end plate and one in the rear end plate. You will need to provide the mounting
apparatus to use with these mounting holes.
The front and rear end plate spacing is 2.95 inches (75.0 mm) and the mounting
holes are located co-axially in line as shown in Figure 4. Each mounting hole is
threaded for a 4-40 machine screw to a depth of 0.38 inches (9.5 mm). The
bottom of the mounting holes are closed in order to prevent accidental damage to
the internal circuits of the remote module from the machine screws.
CAUTION. Do not use machine screws in the end plate mounting holes that can
protrude deeper than 0.38 inches (9.5 mm). Such screws may bottom out in the
closed mounting holes and damage the screw threads or break off.

To prevent electrostatic damage to your mainframe and sampling modules,
follow the precautions described in this manual.
Slide the remote module

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.
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.
