Getting Started
Installation
The 80A05 module fits into one of the large module compartments on the front
panel of an 8000 series instrument. See Figure 1.
To install a module, first power 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 the module is seated, turn the hold-down screws on
the module to tighten the module into place. See Figure 1. When an 80A05
module is installed into one of the large slots, one of the smaller slots will be
disabled. Refer to the instrument’s online help to identify the disabled slot.
CAUTION. To prevent damage to the module or instrument, never install or
remove a module when the instrument is powered on or when either input
connector is unprotected.

80A05 Electrical Clock Recovery Module User Manual
Getting Started
Electrostatic Discharge
To prevent electrostatic damage to the main instrument and modules, follow the
precautions described in this manual and the manuals that come with your
instrument.
Circuitry in the module is very susceptible to damage from electrostatic
discharge or from overdrive signals. Be sure to only operate the 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 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 10 V maximum source connected to a 1 V maximum module, use
a 10X attenuator. Where possible, connect your cables to the signal source first,
and to the module second.
CAUTION. To prevent damage from electrostatic discharge, install the attached
50 Ω terminations on the I/O connectors before removing the module from an
instrument, storing, or when not in use. Store the module in a static-free
container, such as the shipping container. Whenever you move the module from
one instrument to another, use a static-free container to transport the module.
Static Controlled
Workstation
T o prevent damage to the module, discharge to ground any electrostatic charge
that may be present on the center and outer conductors of cables before
attaching the cables to the module.
T o prevent damage to the module, do not create an ESD antenna by leaving
cables dangling off the module input with the other end open.
T o prevent damage to the module or instrument, never install or remove a
module when the instrument is powered on.
Always use a wrist strap (provided with your instrument) when handling
modules or making signal connections. Wear antistatic clothing and work in a
static-free workstation when using modules.
T o prevent damage to the module or instrument, do not apply a signal outside
the Maximum Input Voltage Swing for your 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.

Operating Basics
Usage
This chapter familiarizes you with the operation of your module. This chapter
describes the front-panel controls and connectors, interaction of the module with
your main instrument, user adjustments, and the programmer interface.
Figures 2 and 3 on page 8, show the front panel of the module and identify the
connectors and indicators.
CAUTION. To prevent damage to your module or instrument, do not apply a
signal outside the Maximum Input Voltage Swing for your module.
T o prevent electrostatic damage to the instrument and modules, follow the
precautions described in this manual and the documentation accompanying your
instrument. (See Electrostatic Discharge starting on page 5.)
Always use a wrist strap (provided with your instrument) when handling
modules or making signal connections.
Front Panel
Hold-down screws
LED
The input circuitry in your module is very susceptible to damage from overdrive
signals and electrostatic discharge. Never apply a DC or peak voltage greater
than the Maximum Operating Range (see Table 4 on page 11) of your module.
Only operate the instrument and module in a static-controlled environment.
The 80A05 module contains three primary features:
Use these to secure the module in the instrument module compartment once
connected. Turn clockwise to secure and counterclockwise to release. To prevent
damage to the module, use the compartment ejectors to remove the module from
the compartment (see Figure 1 on page 4 for the location of the ejectors).
The 80A05 module has one LED on its front panel. When on, it indicates the
module’s clock recovery output has been selected as the trigger source. The LED
is off when the module is not selected as the trigger source.

Input and Output
Connectors
System Interaction
The connectors on the front panel of the 80A05 module provide connections for
the input and output signals. All connectors are SMA female connectors.
Connector Care. Never attach a cable to a sampling-module connector if the cable
has a worn or damaged connector because you may damage the sampling-module connector. Use extra care when attaching or removing a cable from the
connectors. Turn only the nut, not the cable. When attaching a cable to a
sampling-module connector, align the connectors carefully before turning the
nut. Use light finger pressure to make this initial connection. Then tighten the
nut lightly with a wrench.
NOTE. For best repeatability and to prolong connector life, use a torque wrench,
and tighten the connection to the range of 79-112 N⋅cm (7-10 in lb).
If the module connectors will receive heavy use, such as in a production
environment, you should install adapters (such as a Tektronix part number
015-0549-xx for 3.5 mm connectors) on the module to make connections to the
device under test.
The mainframe acts as the host via the large module receptacles for this module.
The remainder of the system interaction for this module is contained in the
documentation set included with your main instrument.
