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.
NOTE: The Auxiliary Inputs can be used as external inputs simply by programming the UPC for 0 VAC
output.
Auxiliary Input voltage range (Vaux):
± 10Vpk (20Vpk-pk)
Input impedance:
600 ohms
Small Signal Gain Bandwidth:
> 100 kHz. (auxiliary inputs to UPC output)
See the power source Operator Manual for
bandwidth of the power output stage.
Form 1 and 3:
Power source OUTPUT VOLTAGE = Vp (Vaux x 25 x XFMRratio).
Form 2:
Power source OUTPUT VOLTAGE = Vp (Vaux x 50 x XFMRratio).
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):
± 10Vdc (20Vpk-pk)
Input impedance:
600 ohms
Power Source OUTPUT VOLTAGE (rms) = Vp (Vam x AMgain x XFMRratio)
AMgain = 21.4 ± .5
Linearity = ± 0.1 over the full Output Voltage range
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
2.3.7 DIGITAL OUTPUTS
J5 digital outputs are 0 to 5 VDC, positive logic.
Logic outputs are:
Transient Trigger:
250 nsec. pulse at the start of a transient event
Transient Pedestal:
true when a transient is in progress
DRM:
frequency generating clock, 1024 times output frequency
SYNC OUT:
Positive Zero Crossing (0°) of Phase A waveform output
F1, F2, F3, F4:
DO NOT CONNECT
– factory diagnostics only
