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
SIGLENT
Company as soon as possible.
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) 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
SIGLENT.
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 to be tested.
4) 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).
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
item at the trigger
panel 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) Change the trigger holdoff setting.
5.
No display after pressing Run/Stop:
Check whether the mode at the trigger panel (TRIGGER) is on “Normal” or “Single”
and whether the trigger level exceeds the waveform range. If yes, set the trigger level
