AEC REFERENCE VOLTAGE, 0 TO 0 VDC, DEPENDING ON AEC TECHNIQUE. THE LENGTH OF THE AEC EXPOSURE IS PROPORTIONAL TO THE AEC REFERENCE VOLTAGE. AEC STOP (PT STOP) SIGNAL. THIS IS NORMALLY HIGH (APPROXIMATELY VDC), SWITCHING LOW WHEN THE AEC RAMP = THE AEC REFERENCE VOLTAGE. REFER TO FIGURE. AEC RAMP. THIS IS A SIGNAL RAMPING FROM 0 TOWARD 0 VDC, THE ACTUAL MAGNITUDE WILL DEPEND ON THE AEC TECHNIQUE. REFER TO FIGURE. AS PER #. PWM OUTPUT. THIS WILL BE VARIABLE WIDTH PULSES (PULSE WIDTH INCREASING AT INCREASING LOAD), UP TO A MAXIMUM OF 0% DUTY CYCLE. REFER TO FIGURE. AEC RAMP OR DC VOLTAGE. THIS IS A RAMP OR DC VOLTAGE, DEPENDING ON AEC CHAMBER TYPE (INTEGRATING OR NONINTEGRATING). REFER TO FIGURE. AS PER #, EXCEPT THAT THE RAMP OR DC VOLTAGE WILL BE POSITIVE GOING AND NOT OF THE SAME MAGNITUDE. THE VOLTAGE AT THIS TEST POINT IS THE OUTPUT OF THE AEC CHAMBER. REFER TO THE AEC CHAMBER MANUFACTURERS DOCUMENTATION FOR DETAILS. THIS IS THE SIGNAL. HIGH ( VDC) = = ANALOG SWITCHES CLOSED, LOW (0 VDC) = = ANALOG SWITCHES OPEN. THIS WILL BE A NEGATIVE DC VOLTAGE. THE MAGNITUDE OF THE DC VOLTAGE IS DEPENDENT ON THE AEC TECHNIQUE IN USE. AS PER #, EXCEPT THAT THE POLARITY WILL BE POSITIVE. THE POLARITY AND MAGNITUDE OF THE RAMP AT THIS POINT SHOULD BE APPROXIMATELY THE SAME AS THE PT RAMP OUTPUT. NOTE REFERENCE.
