VS_DA Located on the Control Board just above the AUTO Gen Test Points may be used as an external trigger source for locking the waveform on the Oscilloscope
External Triggering of the Oscilloscope allows for a Stable Display of both the Y and Z SUS Output Waveforms regardless of how distorted the waveforms may be, allowing the wave shape and phasing to be easily examined.
