Triggering on a Waveform

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.)

Setting Trigger Level and Slope

￿ Perform an AUTO SET.

For quick operation, use the AUTO SET key to automatically trigger on nearly all signals. To optimize trigger level and slope manually, do the following:

￿	Press until you have left any open
	menu.
￿	Enable the arrow keys for Trigger
	Level and Slope adjustment.

￿

￿

Adjust the Trigger Level continuously. Observe the trigger icon on the second time division line indicates the trigger level.

Trigger on either positive Slope or negative Slope of the chosen waveform.
