29 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 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 contact SIGLENT timely and return the instrument
to the factory for replacement by the maintenance personnel
authorized by SIGLENT.
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.
5) Resample the signal.
