Troubleshooting
The commonly encountered failures and their solutions are listed below. When you
encounter those failures, please solve them following the corresponding steps. If the
problem remains still, please contact RIGOLand provide your device information
(acquisition method: UtilitySystemSystemInfo).
1. The screen is still dark (no display) after you powered on the
instrument.
(1) Check whether the power switch is turned on.
(2) Check whetherthe power is correctly connected.
(3) Check whetherthe fuse is burned out. If the fuse needs to be changed,
please use the specified fuse.
(4) Restart the instrument after finishing the above inspections.
(5) If it still persists, please contactRIGOL.
2. The signal is sampled but no waveform of the signal is displayed.
(1) Check whetherthe probe is correctly connected to the item under tested.
(2) Check whethersignals are generated from the item under test (you can
connect the probe compensation signal to the problematic channel to locate
the problem).
(3) Resample the signal.
3. The voltage amplitude measured is greater or smallerthan the actual
value (note that this failure usually only occurs when probe is used).
Check whether the attenuation ratioof the channel complies with the attenuation
ratio of the probe.
4. Waveforms are found to be displayed but not stable.
(1) Check the trigger signal source: press MENUofthe TRIGGER Control
Areaonthe front panel, then press Sourceto confirmwhether the setting
complies with the signal channel actually used.
(2) Check the trigger type: general signals should use "Edge" trigger and video
signal should use "Video" trigger. Only when the proper trigger type is used,
can the waveform be displayed stably.
(3) Check the trigger level: adjust the trigger level to the middle of the signal.
