Chapter 4 Troubleshooting

1. After the oscilloscopes is powered on, the screen remains dark (no

display):

(1) Check the power cable connection.

(2) Check if the power switch is turned on.

(3) After the above inspection, restart the oscilloscope.

(4) If the problem still remains, please contact RIGOL for help.

2. After the signal acquisition the waveform does not appear:

(1) Check if the probes are correctly connected with the signals.

(2) Check if the probes are firmly connected to the channels.

(3) Check if the probes are correctly connected with the object being tested.

(4) Check if the circuit can generate signal at the test point (Connect the probe

compensator output to an input channel to confirm whether the testing point

has no signal or the input channel is in some troubles).

(5) Repeat the acquisition.

3. The measurement result is 10 times higher or lower than the value

expected.

Check if the probe attenuation is the same as the channel attenuation.

4. If the oscilloscope does not get a stable waveform display:

(1) Check the Trigger Source and notice if it is set to the channel in use.

(2) Check the Trigger Type. 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 hold off time.

5. After pressing the RUN/STOP button, the oscilloscope does not display

any waveform on screen.

Check whether the Trigger Mode is set to “Normal” or “Single” and see

whether the trigger level is out of the signal range. If yes, set the trigger level in

1 2 ... 142 143 144 145 146 147 148 149 150 151 152 ... 161 162
