You can run individual tests, loop on tests, or run until a failure occurs by
selecting the options at the right side of the property page. When you first
display the extended diagnostics property page, some of the test results may
display an Unknown test result. This indicates that parts of the tests did not get
checked by the power-on tests. When you click the Run button on the property
page, the extended diagnostics run and the unknown state should change to either
Pass or Fail. Table 6--11 indicates the system tests that are checked in more detail
with the extended diagnostics.
For more information on the extended diagnostics refer to the online help by
clicking on the Help button in the property page.
The TLA Mainframe Diagnostics are comprehensive software tests that check
benchtop mainframe as well as the benchtop controller. If the TLA Mainframe
Diagnostics test fails to run correctly, the benchtop controller is defective.
To run the TLA Mainframe diagnostics, do the following steps:
1.
Quit all other applications on the instrument.
2.
Click on START in the tool bar.
3.
Select Programs from the Start menu.
4.
Select Tektronix Logic Analyzer from the Programs menu.
5.
Select TLA Mainframe Diagnostics from the Tektronix Logic Analyzer
menu. (Refer to the online help in the TLA Mainframe Diagnostics
application for information on running the TLA Mainframe Diagnostics).
At power-on, the instrument runs two power-on diagnostics for any attached
expansion mainframes: “Power, Cables A & B and config”, and “Cable C
Connection Test”.
If either of these power-on diagnostics fail, none of the modules associated with
the expansion mainframe, and possibly the expansion mainframe itself, will be
recognized. The result will be as if the expansion mainframe was not connected.
If the instrument passes all other diagnostics and you still suspect problems, you
can run the CheckIt Utilities. The CheckIt Utilities is a third-party software that
allows you to check the main part of the PC controller such as memory, I/O
ports, disk drives, keyboard, and mouse.
To run the CheckIt Utilities, you must have either a working keyboard, a
pointing device (mouse), and Windows must be running. Before starting the
utilities install a test floppy disk in the floppy disk drive and a test CD in the
CD-ROM drive. Refer to the CheckIt Utilities online help for additional
information on running the utilities.
