2: Channel 1 control bar key area, click this area to pop up the parameter control bar
of channel 1
3: Channel 2 control bar key area, click this area to pop up the parameter control bar
of channel 2
4: Movement speed button area, click here to switch between fast movement and
slow movement
5: trigger control bar key area, click here will pop up trigger parameter control bar
6: trigger voltage button area, press here and slide up and down to adjust the trigger
voltage (trigger threshold)
7: The time base shrinks the key area, that is, the waveform is stretched and enlarged
in the horizontal direction. The display area to the right of the centerline of the
background grid is the key area.
8: The time base increases the key area, that is, the waveform is pushed horizontally
to shrink. The area to the left of the centerline of the background grid is the key area.
9: Channel 2 horizontal baseline button area. Press here and slide up and down to
adjust the baseline position of Channel 2. You can also directly click the waveform to
move the horizontal baseline (waveform moves up and down). The left and right
movement buttons of the waveform are the entire display. Area
10: Channel 1 horizontal baseline button area. Press here and slide up and down to
adjust the baseline position of channel 1. You can also directly click the waveform to
move the horizontal baseline (waveform moves up and down). The left and right
movement buttons of the waveform are the entire display. Area
