A trigger is an input signal that cause the signal generator to perform an action such as starting or stopping a generation operation. Triggers can be internal (software-generated) or external.

External digital triggers have different types and can be re-exported. When used with events, triggers can enable you to synchronize the hardware operation with external circuitry or other NI devices.

When triggering your NI signal generator, you can select the trigger type, the trigger source, and the trigger mode that you want to use.
