4.1 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 4-2.
Figure 4-2 Current Channel and Non-Current Channel
The display content of the oscilloscope channel display interface includes the sampling mode, vertical scale,
vertical scale sensitivity button, probe ratio, bandwidth limitation, etc. of the channel, as shown in Figure 4-3.
Figure 4-3 Channel Display Interface
When CH1 is on, but the state is not the current channel, tap CH1 waveform or vertical sensitivity or channel
indicator
or vertical sensitivity button or current channel selection button to set CH1 as the current
channel, as shown in Figure 4-4.
