complies with the attenuation ratio of the probe.
4. There is waveform display but not stable:
(1) Check the trigger signal source: check whether the
Source item at the trigger panel complies with the signal
channel actually used.
(2) Check the trigger type: general signals should use “Edge”
trigger and video signal should use “Video” trigger. Only
when the proper trigger type is used, can the waveform
be displayed stably.
(3) Check the trigger level: adjust the trigger level to the
middle position of the signal.
(4) Change the trigger holdoff setting.
5. No display after pressing RUN/STOP:
Check if the MODE at the front panel TRIGGER control area is
on “Normal” or “Single” and if the trigger level exceeds the
waveform range. If yes, set the trigger level to the middle or
set the MODE to “Auto”.
Note: using AUTO could automatically finish the above
setting.
6. The display of waveform is ladder-like:
(1) The horizontal time base might be too low. Increase the
horizontal time base to increase the horizontal resolution
and improve the display.
(2) If Type is “Vectors”, the lines between the sample points
may cause ladder-like display. Set Type to “Dots” to
solve the problem.
