AO Start Trigger Signal

Use the AO Start Trigger (ao/StartTrigger) signal to initiate a waveform
generation. If you do not use triggers, you can begin a generation with a
software command.

Retriggerable Analog Output

The AO Start Trigger can be configured to be retriggerable. The timing
engine will generate the sample clock for the configured generation in
response to each pulse on an AO Start Trigger signal.
The timing engine ignores the AO Start Trigger signal while the clock
generation is in progress. After the clock generation is finished, the counter
waits for another Start Trigger to begin another clock generation.
Figure 5-4 shows a retriggerable AO generation of four samples.

Using a Digital Source

To use AO Start Trigger, specify a source and an edge. The source can be
one of the following signals:
