This system allows you to obtain conveniently programmed power supply outputs which you may use to evaluate performance of airborne eqquipment against power supply changes meeting the requirements of MIL-STD-704A. With the built-in system computer, you can readily program the standard airborne equipment power supplies [115 V, 400 Hz, 3-phase AC; 28 V DC] for test with changes in starting time difference between AC and DC,and in duration, amplitude, and other parameters.

Typical test output waveforms
	3-phase output change waveform	Test of DC change after starting AC change
	Start of AC change after starting DC change	Setting the starting gradient
