19. Trigger Control
There are two trigger modes: alternate trigger and single trigger.
Single trigger: Use a trigger level to capture stable waveforms in two channels simultaneously
Alternate trigger: Trigger nsynchronous signals steadily. The two channels could acquire the waveforms when
the CH1 and CH2 are inputting two different frequency signals.
Single trigger
Single trigger mode have edge trigger and video trigger, you can see different trigger type for two vertical
channels in this menu.
Edge Trigger: It happens when the trigger input passes through a given level along the set direction.
Video Trigger: Carry out the field or line video trigger of the standard video signal.
The Edge and Video Trigger menus are described respectively as below:
Edge Trigger
Under the Edge Trigger mode, a trigger happens in the trigger threshold value of the input signal edge. When
the Edge Trigger is selected, a trigger will occur in the rising or falling edge of the input signal.
The Edge Trigger Menu is shown as Fig. 26.
