5.4 Open Channel Menu
Tap the channel icon (channel is open) to open the channel menu.
The channel menu is shown in Figure 5-7. Channel waveform inversion, channel bandwidth limit, probe type, probe
attenuation factor, channel coupling mode, and sampling mode can be set in the vertical menu.

5.4.1 Measured Signal
Tap the icon on the right side of "Measured signal" to select two channel coupling modes, "DC" and "AC".
DC:
DC coupling. Both the DC component and the AC component of the measured signal can pass, and can be used
to view waveforms as low as 0 Hz without large DC offset.
AC:
AC coupling. Measured DC signal is blocked, and only the AC component can be allowed to pass, and used to
view waveforms with large DC offsets.
The oscilloscope is connected to the square wave signal with a frequency of 1KHz, an amplitude of 2V and an offset
of 1V. The waveforms of the channel couplings of DC, AC are shown in Figure 5-8, 5-9.
