TLA700 Series Logic Analyzer Installation Manual
Before running the extended diagnostics, disconnect any attached probes.
TLA Mainframe Diagnostics.
The TLA mainframe diagnostics program is a
stand-alone application. These diagnostics check the operation of the mainframe
beyond the basic PC circuitry. These diagnostics also check the front-panel
knobs of the portable mainframe.
CheckIt Utilities.
The CheckIt Utilities is a separate application located in the
Windows Start Programs menu (Start > Programs > CheckIt Utilities). The
diagnostics check the basic PC operations of the controller.
Your logic analyzer comes with most software installed. Before running any of
the diagnostics, check the online release notes to verify that the logic analyzer
software is compatible with the module firmware.
Many software problems can be due to corrupted or missing software files. In
most cases the easiest way to solve software problems is to reinstall the software
and follow the on-screen instructions. Refer to
Restoring and Reinstalling
Software
beginning on page 41 for instructions on reinstalling or upgrading
software.
If you are certain that you have installed the logic analyzer correctly, run the
extended diagnostics (located under the System menu) to identify any problems.
If your logic analyzer powers up so that you have access to the desktop, run the
CheckIt Utilities software to identify possible controller hardware problems.
You can also run the external TLA mainframe diagnostics to identify problems
not covered by other diagnostics. The TLA mainframe diagnostics are located
under the Start menu under the Tektronix Logic Analyzer programs.
Repacking for Shipment
If a mainframe or module is to be shipped to a Tektronix service center for repair,
attach a tag to the mainframe or module showing the owner’s name and address,
the serial number, and a description of the problem(s) encountered and/or service
required. Always include the module and the probes so that the entire unit can be
tested.
When packing an instrument for shipment, use the original packaging. If it is
unavailable or not fit for use, contact your Tektronix representative to obtain new
packaging.
