occurred, an error message is printed to the screen. The message displays
the test number, group number, the value expected, and the value received.
Contact National Instruments for further interpretation of diagnostic error
messages.
You can suppress the error reporting with the e command. With error
reporting turned off, you can select and run tests to completion without
being interrupted by error messages. The GPIB-VXI/C informs you if any
errors
have
occurred
after
all
the
tests
you
selected
have
completed. To view
the errors, select
r
to display the error log. Select
c
to clear the error log.
Single Step Toggle is another useful feature you can use to pinpoint
problems. Select s to toggle this command on or off. With this feature,
each access to memory or to a register is reported on the screen. In addition,
the GPIB-VXI/C waits for you to press a key before actually performing
the displayed step.
Diagnostic Test Selection
If you select the Default Diags (all) option or the Over Night Loop option,
the appropriate tests begin immediately. The default option performs all of
the tests, while the Over Night Loop option performs all except the
interactive tests and tests that drive signals on the VXIbus. When you select
either the Tests or the Test Groups option, a new menu appears from which
you can select any or all tests or test groups. The following example shows
the Test Selection menu. The Test Group Selection menu is very similar.
