WFM700 Series Waveform Monitors Service Manual
Diagnostics
The waveform monitor provides diagnostics capabilities, which are accessed
through the System submenu of the Configure menu. You can view or print the
Diagnostics Log, which contains the results of the last diagnostic test that the
instrument performed.
The instrument runs either full or brief diagnostics at power up, depending on the
Powerup Diagnostics setting in the System submenu of the Configure menu.
You should run diagnostics after installing a new module, software upgrade or
firmware upgrade, or when troubleshooting suspected instrument problems. You
have the following diagnostic choices:
Run Full Powerup Diagnostics. The instrument goes through all of the diagnostics
and displays the results for the various tests. Warning messages are displayed in
yellow text; PASS and FAIL messages are labeled PASS (green text) or FAIL
(red text).
Run Internal Digital Path Diagnostics. The instrument checks the main digital
paths within the instrument and displays the results of the various tests. If there
is only one input card installed, expect some yellow warnings.
NOTE
. Running the Internal Digital Path Diagnostics sets the instrument into a
special diagnostics configuration mode. After running this diagnostic, you must
reboot the instrument to return to normal operation.
Run Audio Path Diagnostics (WFM7DG Only).
The instrument checks the audio
paths within the instrument from the optional WFM7DG audio module and
displays the results of the various tests.
NOTE
. Running the Audio Path Diagnostics sets the instrument into a special
diagnostics configuration mode. After running this diagnostic, you must reboot
the instrument to return to normal operation.
