Instrument Software Requirements
The 80A01 prescaled trigger amplifier was designed to be used with software
release versions 1.1.0 and later of the 8000 series sampling oscilloscope
application. If your instrument is running a release prior to version 1.1.0,
Tektronix recommends that you upgrade your instrument to the latest version.
To determine the software version running on your CSA8000 or TDS8000, select
About TDS/CSA in the Help menu from the user interface. This command
displays the About TDS/CSA dialog which lists the current software version
number.
If you find that you are running an older version of software, please visit the
Tektronix website at http://www.tektronix.com to find out how to get an upgrade
version mailed to you. When you visit the Tektronix website, select the Oscillo-
scopes page. You will find upgrade information there.
While the 80A01 was designed to be used with software release 1.1.0 or later, it
can be used with earlier versions of the software with the following limitations
and non-standard behavior:
1. If the 80A01 is inserted in the left-most small slot (labeled CH1 / CH2) of
the TDS/CSA8000 and at least one optical module is present, the 80A01 will
behave normally.
2. If the 80A01 is inserted in any other slot or there are no optical modules
present, the following behavior will be seen:
a. The instrument will behave as if the odd-numbered channel for the slot
in which the 80A01 is inserted is available for acquisition. Thus if the
module is inserted in the right-most small slot, the TDS/CSA8000 will
believe that it can acquire data on Channel 7. Turning on acquisition on
this ”pseudo-channel” will result in a waveform being acquired from a
floating input. This pseudo-waveform will appear as a DC level with all
points having amplitude approximately equal to zero.
b. The System Properties dialog (accessed by selecting System Properties
from the Utilities menu in the user interface) may contain incorrect
information.
In either scenario (1. or 2.), the actual performance of the 80A01 in amplifying
RF signals is not degraded.

Installation
The 80A01 module fits into one of the small module compartments on the front
panel of an 8000 Series instrument. Figure 2 shows the front panel of an
instrument and the locations of the small module compartments.
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 screw on
the module to tighten the module into place. See Figure 2.
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.

Getting Started
80A01 Trigger Prescale Limiting Preamplifier Module User Manual 5
To prevent electrostatic damage to the 8000 Series 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 50 W
terminations (Tektronix part number 015-1022-xx) on the I/O connectors before
removing them from an instrument, storing a module, 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.
To 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 cable to the module.
To prevent damage to the module, do not create an ESD antenna by leaving
cables dangling off the module input with the other end open.
To 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 anti-static clothing and work in a
static-free workstation when using modules.
To 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 Electron-
ic Industries Association document EIA-625; Requirements for Handling
Electrostatic-Discharge-Sensitive (ESDS) Devices.

Operating Basics
This chapter makes you familiar with the operation of your module. This chapter
describes the front-panel controls and connectors, interaction of the module with
your instrument, user adjustments, and the programmer interface.
Usage
Figure 3 shows the front panel of the module and identifies 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.
To prevent electrostatic damage to the instrument and modules, follow the
precautions described in this manual and the manuals 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.
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 Input Voltage (see page NO TAG) of your module. Only
operate the instrument and module in a static-controlled environment.
Front Panel
The 80A01 module contains three primary features:
Use this 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 2 on page 4 for the location of the ejectors).

The two connectors on the front panel of the 80A01 module provide connections
for the input and output signals. Both 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-mod-
ule 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 inSlb).
If the module connectors will receive heavy use, such as in a production
environment, you should install adapters (such as a Tektronix 015-0549-xx for
3.5 mm connectors) on the module to make connections to the device under test.
There is one LED on the front panel of the 80A01 module that indicates whether
or not the module is receiving power. The 80A01 module receives power through
the Tekprobe-Sample interface. When the module is receiving power the LED is
lit. If the module is installed but is not receiving power, check that the module is
seated correctly. Additionally, turn the hold-down screw clockwise to make sure
the module is installed tightly.

System Interaction
The 80A01 module is part of a larger instrument system. This module functions
as a preamplifier for the prescaler trigger input. You connect a voltage to the
input connector and it is automatically passed through the amplifier. You then
send the output voltage where you want it to go for testing and evaluation.
The remainder of the system interaction for this module is contained in the
documentation set included with your TDS8000 or CSA8000 instrument. See the
8000 Series User Manual prescale trigger section for more information on how
to use signals output from the 80A01 module.
Programmer Interface Commands
The remote-programming commands for all modules are documented in the
CSA8000 & TDS8000 Programmer Online Guide.
User Adjustments
All module setups, parameters, and adjustments are controlled by the instrument.
To save, recall, or change any module settings, use the instrument menus or
front-panel controls or consult the CSA8000 & TDS8000 User Manual or
