SIGLENT
24 SDS/SD Quick Start
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 coefficient 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 false: it is easy for us to regard the
false 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 display.
(4) Change the setting of trigger holdoff.
5. No display after pressing :
Check whether the trigger Mode is “Normal” or “Single”, and if
the trigger level exceeds the waveform range. If yes, set the
trigger level to the vertical center or change the trigger Mode to
“Auto”.
Note: press could automatically replace the above
setting.
6. The waveform displays like ladder:
(1) The horizontal time base may be too low, you can increase it
to improve the horizontal resolution so as to make a good
waveform displaying.
(2) The lines between the sample points may also cause
ladder-like displaying if the “Type” in menu of “DISPLAY” is
“Vectors”. Please turn the “Type” to “Dots” to solve the
problem.
