5.1 Open/Close Waveform (Channel, Math, Reference Waveforms)
The channel icons , , , , on the right side of the oscilloscope waveform display
area (tap to switch to math channel and reference channel) correspond to the six channels of CH1, CH2, CH3,
CH4, math function and reference channel. Click these six soft keys can cyclically realize the functions: open the
channel, open the channel menu, and close the channel.
Current channel: The oscilloscope can display multiple waveforms at the same time, but only one waveform is
preferentially displayed on the uppermost layer, and the channel that is preferentially displayed on the uppermost
layer is called the current channel. The channel indicator for the current channel is solid, and the channel indicator
for the non-current channel is hollow, as shown in Figure 5-2.
