Short Name: Reference Position

Property of niScope

Specifies the position of the Reference Event in the waveform record as a percentage of the record.

When the digitizer detects a trigger, it waits the length of time the Trigger Delay property specifies. The event that occurs when the delay time elapses is the Reference Event. The Reference Event is relative to the start of the record and is a percentage of the record length. For example, the value 50.0 corresponds to the center of the waveform record and 0.0 corresponds to the first element in the waveform record.
