Triggers
Triggers are signals that cause the NI device to perform some action such as the starting, stopping, or pausing of an acquisition or generation operation. Triggers can be internal (software-generated) or external. External digital triggers can be several different types. External triggers can be re-exported and, along with events, can allow you to synchronize the hardware operation with external circuitry or other NI devices.
Refer to Triggers Summary and Events Summary for descriptions of the triggers and events you can use with your device.
