SECTION 2 SPECIFICATIONS

2.3.6 ANALOG INPUTS

Three Auxiliary Inputs are provided on J5, one per phase. The Auxiliary Inputs are AC coupled and
algebraically summed to the Oscillator signals produced by the UPC. It should be noted that the
Auxiliary Inputs can be used as external inputs simply by programming the UPC for 0 VAC output.
Auxiliary Input voltage range (Vaux):
Input impedance:
Small Signal Gain Bandwidth:
Form 1 and 3:
Form 2:
Three AM Inputs are provided on J5, one per phase. Varying DC voltage may be used to Amplitude
Modulate the output.
AM Input voltage range (Vam):
Input impedance:
Power source OUTPUT VOLTAGE = Vprogram + (Vam/10 x (150 x XFMRratio) x 1.414)

2.3.7 DIGITAL OUTPUTS

Digital outputs on J5 are 0 to 5 VDC, positive logic.
Logic outputs are:
Transient Trigger:
Transient Pedestal:
DRM:
SYNC OUT:
F1, F2, F3, F4:
Power source OUTPUT VOLTAGE = Vprogram + (Vaux x 25 x XFMRratio).
Power source OUTPUT VOLTAGE = Vprogram + (Vaux x 50 x XFMRratio).
(The maximum voltage is limited by the output voltage range of the power source.
NOTE: Attempting to drive the OUTPUT VOLTAGE beyond the voltage range of the
power source will result in a clipped (distorted) output waveform)
