A. Select signals of Channel A as the trigger signal source.
B. Select signals of Channel B as the trigger signal source.
AB. Select signals of Channels A and B as the alternate trigger signal source
2. Trigger coupling mode display is as follows:

can pass the coupling capacitor. The DC% will be intercepted. This is a general trigger
coupling mode.
