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 front 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) Try to change the Coupling to "HF Reject" or "LF Reject"
to filter out the high-frequency or low-frequency noise that
disturbs the trigger.
(4) Change the trigger sensitivity and the trigger holdoff
setting.
5. No display after pressing Run/Stop:
Check if the MODE at the trigger panel (TRIGGER) 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". Besides, pressing the Auto button 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.
