⑵
Af
⑶
ter the inspections above
,

If the oscilloscope is still not used after the checking, please connect with
⑷
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 as 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
