Troubleshooting
The commonly encountered failures and their solutions are listed below. When you
encounter those problems, please solve them following the corresponding steps. If
the problem remains still, please contact RIGOL and provide your device
information (acquisition method: Utility System System Info).
1. The screen is still dark (no display) after power on:
(1) Check whether the power is correctly connected.
(2) Check whether the power switch is really on.
(3) Restart the instrument after finishing the above inspections.
(4) If it still does not work correctly, please contact RIGOL.
2. The signal is sampled but no waveform of the signal is displayed:
(1) Check whether the probe is correctly connected to the signal connecting
wire.
(2) Check whether the signal connecting wire is correctly connected to the BNC
(namely channel connector).
(3) Check whether the probe is correctly connected to the item under test.
(4) Check whether there are signals generated from the item under test (you
can connect the probe compensation output signal to the p roblematic
channel to determine which has problems, the channel or the item under
test).
(5) Resample the signal.
3. The tested voltage amplitude is greater or lower than the actual value
(note that this problem usually occurs when probe is used):
Check whether the attenuation coefficient of the channel complies with the
attenuation ratio of the probe.
4. There is waveform display but not stable:
(1) Check the trigger signal source: check whether the Source in the trigger
menu 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) Try to change the Coupling to “HF Reject” or “LF Reject” to filter out the
high-frequency or low-frequency noise that disturbs the trigger.
(4) Change the trigger holdoff setting.
5. No display after pressing RUN/STOP:
Check whether the MODE at the trigger panel (TRIGGER) is “Normal” or
“Single” and whether the trigger level exceeds the waveform range. If yes, set
the trigger level to the middle or set the MODE to “Auto”.
Note that using the AUTO button could automatically finish the above setting.
6. The display of waveform is ladder-like:
(1) The horizontal time base might be too low. Increase the horizontal time
base to increase the horizontal resolution and improve the display.
(2) If the display Type is “Vectors”, the lines between the sample points may
cause ladder-like display. Set Type to “Dots” to solve the problem.
7. Fail to connect PC or printer through USB:
Check the IO Setting menu in Utility to make sure whether the setting in USB
Device matches the currently connected device. If needed, restart the
oscilloscope.
8. The USB storage device can not be recognized:
(1) Check whether the USB storage device can work normally.
(2) Make sure that the USB storage device used is flash storage type. This
oscilloscope does not support hardware storage type.
(3) Make sure whether the capacity of the USB storage device is too large. It is
recommended that the capacity of the USB storage device being used with
this oscilloscope is no larger than 8 GBytes.
(4) Restart the instrument and then insert the USB storage device.
(5) If the USB storage device still can not be used normally, please contact
RIGOL.
