7.2 Edge Trigger

When the edge of trigger signal reaches a certain trigger level, the set signal is triggered and generated. Trigger

occurs on either edge of the rising edge (indicating icon

at the top of the screen), falling edge ( ) or dual edge

( ), and the trigger level can be set to change the vertical position of the trigger point on the trigger edge, namely

the intersection point of the trigger level line and the signal edge. The stable waveform can be obtained by correctly

setting the edge trigger coupling mode. Edge trigger menu is shown in the table below:
