TLA7AXX Logic Analyzer Module Service Manual

Required Documentation

You may need to refer to additional service manuals to isolate faults. In addition,
other manuals and other sections in this manual contain instructions you will
need to complete repairs after locating a faulty part. For a list of supplemental
documentation, refer to the following table.

Manual or Section

Purpose

TLA715 Portable Mainframe Service Manual

or

TLA721 Benchtop Mainframe & TLA7XM

Expansion Mainframe Service Manual

To eliminate benchtop or portable mainframe
as problem source (whichever configuration is
in use)

Tektronix Logic Analyzer Family User Manual

To remove and reinstall modules in mainframe

TLA7UP Mainframe Field Upgrade Instruction
Manual

To reinstall Windows 2000, the TLA applica-
tion software on mainframes or to upgrade
module firmware when required

Check for Common Problems

Use Table 6--4 to quickly isolate possible failures. The table lists problems
related to the logic analyzer module and possible causes. The list is not
exhaustive, but it may help you eliminate a problems that are easy to fix.

CAUTION.

To avoid damaging the logic analyzer module or the mainframe, be

sure to power down the mainframe before removing or reinstalling any modules.
