To troubleshoot the logic analyzer
1
Ensure that the analyzer is connected to a live power source.
If not, connect to a live power source and turn on the analyzer. If the
symptoms recur, go to step 2.
2
Is there an interface module connected to the logic analyzer?
If yes, do the following steps. If not, go to step 3.
a
Turn off the logic analyzer.
b
Remove the module.
c
Turn on the logic analyzer, then check for the failing symptom.
If the failing symptom disappears, replace the module. If not, go to
step 3.
3
Disconnect any external cables from the front panel.
4
Disconnect the power cord, then remove the cover.
See chapter 6, “Replaceable Parts,” for disassembly procedures.
5
Connect the power cord, then turn on the logic analyzer.
If the display comes on after a few seconds, (HP logo and copyright text,
followed by a graticule with text at top of the display) go to “To check the
LVPS.” If after checking the LVPS the voltages are within the test limits, go to
step 9. If not, go to step 7. If the display did not come on, do the steps below.
a
Check the intensity knob to verify whether the setting is too low.
b
If there is still no display, disconnect the power cord.
c
Check all cable connections.
d
Go to “To check the LVPS.”
If the voltages are within the limits go to step 6. If not, go to step 7.
