Trigger Setup
Using Sequence Trigger (A (Main) and B (Delayed))
Combine an edge A Event (Main) trigger with the B Event (Delayed) trigger to capture m ore complex signals. After the A
Event occurs, the trigger system looks for the B Event before triggering and displaying the waveform.
A and B triggers can (and typically do) have separate sources.
NOTE. You can select sequence triggering when you choose the slope type Falling or Rising — but not when you pick
the slope type Both.
Use the Edge trigger menu to set up the A trigger first. Then, to use the B trigger:
1. P ush Trigger Menu.
2. Push Type.
3. Turn Multipurpose a to select a trigger type
of Sequence (B Trigger).
This brings up the Sequence (B Trigger)
menu.
4. Push BTriggerAfterA.
