TLA7Nx, TLA7Px, & TLA7Qx Logic Analyzer Module Service Manual

Eliminate Other Problem Sources

The logic analyzer module is part of the TLA700 Series Logic Analyzer, which
consists of modules installed in either the benchtop or portable mainframe. The
following procedures will help you eliminate the mainframe and other modules
as possible sources of the failure(s) that you troubleshoot.

If you have available a known-good logic analyzer module, perform the
following procedure:

1.

Remove the suspect logic analyzer module from the mainframe.

2.

Install a known-good logic analyzer module in the same slot as the suspected
module (verify that address switches on the rear of the module are set to
same address as the module that you are replacing).

3.

Power-on the logic analyzer and check for normal operation.

4.

If the failure symptoms are still present with the known-good logic analyzer
module installed, the problem most likely is in the portable mainframe or
benchtop mainframe, not in the logic analyzer module.

NOTE

. Viewing the diagnostic window from the TLA700 logic analyzer applica-

tion may help you isolate failures to individual modules or to the mainframe.

5.

If the logic analyzer operates normally with the known-good logic analyzer
module installed, the suspect logic analyzer module needs to be repaired.
Refer to

Troubleshooting the Logic Analyzer Module

on page 6--31 for the

troubleshooting procedures you need to locate faults.

Substitute a Good Module
