Text: Any event which can be used as a timing reference. A trigger for an oscilloscope will initiate the sweep of the beam across the face of the CRT. A trigger signal for a digital vector filter is a Keyphasor pulse which serves to align the center frequency and the band-pass filter to shaft rotative speed and to probe a reference from which to measure rotative speed, 1X amplitude, and phase angle.
