Troubleshooting
Solving General Problems with the Oscilloscope
This section describes how to solve general problems that you may encounter
while using the Keysight DSOX1204A/G oscilloscopes.
If there is no display
✔
Check that the power cord is firmly seated in the oscilloscope power
receptacle.
✔
Check that the power source is live.
✔
Check that the front-panel power switch is on.
✔
If there is still no display, go to the troubleshooting procedures in this chapter.
If there is no trace display
✔
Check that the Intensity (on the front panel) is adjusted correctly.
✔
Recall the default setup by pressing
[Default Setup]
. This will ensure that the
trigger mode is Auto.
✔
Check that the probe clips are securely connected to points in the circuit under
test, and that the ground is connected.
✔
Check that the circuit under test is powered on.
✔
Press the
[Auto Scale]
key.
✔
Obtain service from Keysight Technologies, if necessary.
If the trace display is unusual or unexpected
✔
Check that the Horizontal time/division setting is correct for the expected
frequency range of the input signals.
✔
The sampling speed of the oscilloscope depends on the time/division setting. It
may be that when time/division is set to slower speeds, the oscilloscope is
sampling too slowly to capture all of the transitions on the waveform. Use peak
detect mode.
✔
Check that all oscilloscope probes are connected to the correct signals in the
circuit under test.
