Chapter 17 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 (Utility  System  System Info).

1. The screen is still dark (no display) after pressing the power key:

(1) Check whether the power switch is really on.

(2) Check whether the power is correctly connected.

(3) Check whether the 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 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 oscilloscope and item to be tested.

(2) Check whether there are signals generated from the item to be tested (you can connect the probe compensation signal to the problematic channel to determine which has problem, the channel or the item to be tested).

(3) Resample the signal.

3. The tested voltage amplitude is greater or lower than the actual value

(this problem usually occurs when probe is used):

Check whether the probe ratio of the channel complies with the attenuation ratio of the probe.

4. There is waveform display but not stable:

(1) Check the trigger source: press MENU  Source in the trigger control area (TRIGGER) at the front panel to check whether the trigger source selected 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.

(4) Change the trigger holdoff setting.

5. No display after pressing RUN/STOP:

Check whether the trigger mode in the trigger control area (TRIGGER) at the front panel is “Normal” or “Single” and whether the trigger level exceeds the waveform range. If yes, set the trigger level to the middle or set MODE to

“Auto”.

Note: Using AUTO 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. Press Display  Type to set the display type to

“Dots” to solve the problem.

7. Fail to connect PC or PictBridge printer through USB:

(1) Press Utility  IO Setting  USB Device to check whether the current setting matches the device currently connected.

(2) Check whether the USB cable is correctly connected to the oscilloscope and

PC.

(3) Check whether the USB cable is in good condition. If needed, restart the oscilloscope.

8. The USB storage device cannot be recognized:

(1) Check whether the USB storage device can work normally.

(2) Make sure that the USB storage device being 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 to check it.

(5) If the USB storage device still cannot be used normally, please contact

RIGOL.
