To check out the oscilloscope
1
Is there an interface module connected to the rear panel of the
oscilloscope?
If yes, do the following steps. If not, go to step 2.
a
Turn off the oscilloscope.
b
Remove the module.
c
Turn on the oscilloscope, then check for the failing symptom.
If the failing symptom disappears, replace the module. If not, go to
step 2.
2
Turn off the oscilloscope for 30 seconds minimum and then turn it on
again.
If an error message (for example,
Vertical cal factors failed
checksum test-defaults loaded
) appears within the waveform
display area, go to "To clear error messages." If error messages do not
appear, go to step 3.
3
Disconnect any external cables from the front panel.
4
Disconnect the power cord, then remove the cabinet.
CAUTION
If you operate the oscilloscope without the cabinet, use an external fan to
blow air across the system board. This air flow is necessary to cool the heat
sinks on the system board.
5
Connect the power cord, then turn on the oscilloscope.
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
Low Voltage Power Supply." If, after checking the Low Voltage Power
Supply, 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 listed here.
a
Check the intensity knob to see if it is set too low for viewing.
b
If there is still no display, disconnect the power cord.
c
Check all cable connections.
d
Go to "To check the Low Voltage Power Supply."
If the voltages are within the limits go to step 6. If not, go to step 7.
