Trigger Setup
Checking Trigger Settings
To quickly determine the settings of some
key trigger parameters, check the Trigger
readout at the bottom of the display. The
readouts differ for edge and the advanced
triggers.
1. Trigger source = channel 1.
2. Trigger slope = rising.
3. Trigger level = 0.00 V.
Edge trigger readout
Using Sequence Trigger (A (Main) and B (Delayed))
Combine an edge A Event (Main) trigger with the B Event (Delayed) trigger to capture more 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 fi rst. Then, to use the B trigger:
1. Push 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 B Trigger After A .
