Z-SUS DRIVE WAVEFORM Y-SUS DRIVE WAVEFORM 50PG20 INTERCONNECT DIAGRAM VZ Bias (RAMP) SUS-UP During SMPS Test (Described below), P803 disconnected; 150Vp/p 1) P801 and P802 connected. Y-SUS and Z-SUS will produce sustain waveforms. 2) P801 connected P802 disconnected, Y-SUS will produce sustain waveform, Z-SUS does not. Y-SUS TP 3) P801 disconnected P802 connected. No SUS waveforms are produced due to a loss of control PWB B+ routed through the Y-SUS PWB. Vs, Va and M5V 52V (AC) rms Z-SUS TP P803 Connector "SMPS" to P701 "Main" VS Adj P801 Us
