niRFSA Configure IQ Power Edge Ref Trigger

Configures the device to wait for the complex power of the I/Q data to cross the specified threshold to mark a reference point within the record.

To trigger on burst signals, add a minimum quiet time (specified by the Minimum Quiet Time property) to ensure the trigger does not occur in the middle of a burst if the acquisition starts while a burst is generating. The quiet time should be set to a value smaller than the time between bursts, but large enough to ignore power changes within a burst.

You can use this trigger with the NI-TClk API.
