DIAGNOSTIC TOOLS
SelfTest EXaminer (STEX) for Microsoft Windows 95
Overview
The STEX program may be used to help graphically interpret the
results of any diagnostic output file generated by Digalog System’s
SelfExec program run on the Series 2040 testers. STEX uses the results of the
diagnostic output file to show the configuration of the tester and evaluate
possible problems with the tester resources based on failed test data and/or
system errors during testing. STEX will use these results to ‘decide’ what the
top three most likely resource problems are in the tester, based on Selftest
output information. These results will be shown graphically on the STEX
interface, highlighting and identifying the potentially problematic resources in
the tester.
STEX can be very useful in aiding an operator who is troubleshooting possible
problems in the Digalog testers by providing a graphical depiction of the
location of potentially faulty tester resources. These resources include all
Testhead boards, the Testhead power supplies, the variable power supplies
and their controller modules, the computer with its Testhead controller card,
and the Selftest unit itself.
Creating the Diagnostic File for STEX
To use STEX to analyze Selftest data, the proper information must be recorded
in the Selftest output file first. A new user selection under SelfExec’s output
configuration has been added to provide this information. To obtain a
diagnostic file for use in STEX, follow these steps
when running SelfExec:
1) Under the ‘ F ile’ menu, select
‘ C onfiguration’.
2) On the configuration form under ‘File
Options’, select either ‘Fail Data Only’ or ‘All
Data’ and select ‘Diagnostic’.
3) Run the desired calibration and function
tests.
