Chapter 6 Troubleshooting
1. After the oscilloscopes is powered on, the screen remains dark (no
display):
(1) Check the power cable connection.
(2) Ensure the power switch has been turned on.
(3) After above inspection, restart the oscilloscope.
(4) If the problem still remains, please ask RIGOL for help.
2. After the signal acquisition the waveform does not appear:
(1) Check if the probe is connecting with the signals.
(2) Check if the probe is connecting to the channels firmly.
(3) Check if the probe is connecting with the object being tested.
(4) Check if any signal generated from testing point.
(5) Repeat the acquisition.
3. The measurement result is 10 times higher or lower than the value
expected.
Check if the probe attenuation corresponds with the channel attenuation.
4. If the oscilloscope does not get a stable waveform display:
(1) Check the Source and notice if it is set to the channel in use.
(2) Check the Mode. Use Edge for normal signals, and use Video for VIDEO
signals.
(3) Switch the Coupling into HF Rejection or LF Rejection in order to filter
the noise which disturbs trigger.
(4) Adjust the trigger Sensitivity and the Holdoff time.
5. After pressing RUN/STOP, the oscilloscope does not display any
waveform on screen.
Check whether the Sweep is set to Normal or Single and see whether the
trigger level is out of the signal range. If it is, set the trigger level in proper range
by turning the knob or pressing the 50% button. Or set the Mode as
AUTO. Moreover, push AUTO button to display the waveform on screen.
6. After the Acquisition was set to “Averages” or Display Persistence is set
ON, the waveform refreshes slowly.
Normal phenomenon.
7. The waveform is displayed on the appearance of ladder.
(1) Normal phenomenon. Maybe the time base setting maybe is too slow. Please
