Triggering on a Waveform

Using The Test Tool	1
Triggering on a Waveform

Triggering tells the test tool when to begin displaying the waveform. You can select which input signal should be used, on which edge this should occur, and you can define the condition for a new update of the waveform. Finally you can tell the test tool to trigger on video signals.

The bottom line of the waveform area identifies the trigger parameters being used. Trigger icons on the screen indicate the trigger level and slope. (See Figure 1-16.)
