Analog Output Triggering Signals

A trigger is a signal that causes an action, such as starting or stopping the acquisition of data. When you configure a trigger, you must decide how you want to produce the trigger and the action you want the trigger to cause. The cDAQ chassis supports internal software triggering, external digital triggering, analog triggering, and internal time triggering.
Analog output supports two different triggering actions: AO Start Trigger and AO Pause Trigger. An analog or digital signal can initiate these actions. Time can also initiate the Start Trigger. Up to two C Series parallel digital input modules can be used in any chassis slot to supply a digital trigger. An analog trigger can be supplied by some C Series analog modules.
Refer to AO Start Trigger Signal and AO Pause Trigger Signal for more information about the analog output trigger signals.

- 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. If you are using an internal sample clock, you can specify a delay from the start trigger to the first sample. For more information, refer to the NI-DAQmx User Manual.
- AO Pause Trigger Signal
Use the AO Pause Trigger signal (ao/PauseTrigger) to mask off samples in a DAQ sequence. When AO Pause Trigger is active, no samples occur, but AO Pause Trigger does not stop a sample that is in progress. The pause does not take effect until the beginning of the next sample.
