4. There is waveform displaying but 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 for us to regard the
wrong waveform as the real 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 suits to video signal. Only in the correct
trigger type can the waveform stably displays.
(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: press
AUTO
could automatically replace the above
setting.
