Setting Coupling to select "HF Reject" or "LF Reject" to filter out the

waveform range. If yes, set the trigger level to the middle or set MODE to

Note: Using AUTO could automatically finish the above setting.
6. The display of waveform is ladder-like:

base properly to improve the display.

cause ladder-like display. Press Display Type to set the display type to
"Dots" to solve the problem.
