matches with the attenuation ratio of the probe.
4. There is waveform displaying but it is 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 to regard the
wrong waveform as the real one when a high frequency signal is
connected to the instrument. Make sure that the
current time base is correct.
(3) Check the trigger type: "Edge" trigger suits to general signal
and "Video" trigger matches to video signal. Only in the correct
trigger type will the waveforms 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 middle or change the trigger Mode to "Auto".
Note:
Auto
By pressing "Auto" thus could authomatically replace the above
setting.
6. The waveform displays like a ladder:
(1) The horizontal time base may be too low, increase it
to improve the horizontal resolution.
(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.
