Trouble
shooting
The general failures and consequential solutions are listed below. When you nd them, please deal with them in the following corresponding ways. If the problem
proves to be unsolvable, please contact SIGLENT as soon as possible.
1. The screen remains dark after power on:
(1) Check if the power is correctly connected.
(2) Check if the power switch is faulted.
(3) Check whether the fuse is burned out. If the fuse needs to be changed, please contact SIGLENT as soon as possible and return the instrument to the factory to
have it repaired by service personnel authorized by SIGLENT.
(4) Restart the instrument after completing inspections above
(5) If it still does not work normally, please contact SIGLENT.
2. After the signal is sampled, there is no corresponding waveform displaying:
(1)Check if the probe is correctly connected to the signal connecting cord.
(2) Check if the signal connecting cord is correctly connected to BNC.
(3) Check if the probe is correctly connected to the item under test.
(4) Check if there are signal generated from the item under test.
(5) Resample the signal.
3.The voltage amplitude measured is higher or lower than the actual value (the error usually occurs in use of the probe):Check if the attenuation
coefcient of the current channel matches with the attenuation ratio of the probe.
4.There is waveform displaying but not stable:
(1) Check the trigger source: check whether the “Source” in menu of “TRIG” is the actual operating channel.
(2) Check if the waveform is wrong: it is easy for us to regard the wrong waveform as the real when a high frequency signal is connected to the instrument. You’d
better make sure that the current time base is correct.
(3) Check the trigger type: “Edge” trigger suits to general signal and “Video” trigger suits to video signal. Only in correct trigger type can the waveform stably
displays.
(4) Change the setting of trigger holdoff.
