3.2 Troubleshooting
1. After the oscilloscope is powered on，the screen remains dark ，please do
as following steps：
⑴ Check the power cable’s connection.
⑵ Ensure the power switch is turned on.
⑶ After the inspections above，restart the oscilloscope.
⑷ If the oscilloscope is still not used after the checking, please connect with
Siglent
2. If there is no signal wave in the screen after gathering the signal, please
do as following steps:
(1) Check the probe connecting with the signal cable or not
(2) Check the signal cable connecting with the BNC connector or not.
(3) Check the probe whether connect with the goods tested or not.
(4) Check the tested goods produce the signal or not.
(5) Gather the signal again.
3. The value of the tested voltage is 10 times higher/lower than the real one ,
please do as following steps:
Check the attenuation quotient whether match the probe attenuation proportion or
not.
4. Display the wave, but not steady, please do the following steps:
(1) Check the signal source on the trigger interface whether or not matches the
signal channel.
(2) Check the trigger mode: normal signal should use the “edge” trigger mode.
The video signal should use the “Video” Trigger mode. The signal would
display steady, only using the matching trigger mode.
(3) Attempt to change the “coupling” into “HF Reject” or “LF Reject” display, so that
the High/low frequency noise disturb the trigger should be filtrated
5. Press “RUN/STOP” button, but no display.
Check the trigger mode on the trigger interface whether or not in the “normal” or
“single”, and check the trigger level is whether or not over the wave range. If yes,
please put the trigger level to the middle position or set the trigger mode to the
“Auto” position. In another hand, you could choose the “Auto” button to set up
