Duration: The length of time the output will be disturbed in seconds, from 100 µs to 85.899
seconds. Voltage excursions of duration shorter than 1 ms may be limited by module
power bandwidth and output loading.
Volt2: The RMS voltage to which the supply will return to, when the disturbance is complete.
The Volt1 or Volt2 values must conform to the limits set in Note 3 above.
The :UPSET? command will return the programmed values. If the command has completed execution,
the returned Duration value will be zero.
Example: Three phase group; 120 volts, 60 Hz; Phase A = 0 degrees (Master module slot 3); Phase
B = 120 degrees (1
st slave slot 6); Phase C = 240 degrees (2 nd slave slot 9). To have all of the modules
drop out at the same moment in time for ¼ cycle starting at Phase A at 90 degrees (Phase B at 330
deg., Phase C at 210 deg.) from the Phase Reference time marker, the following command sequence
would be used:
SOUR9:VOLT:UPSET 90.0,0.0, 4.1666667e-3,120.0
SOUR6:VOLT:UPSET 90.0,0.0, 4.1666667e-3,120.0
*OPC9?
// These *OPC?’s will return 0, which means that the commands were
*OPC6? // processed, but are waiting to be triggered by the Master module.
SOUR3:VOLT:UPSET 90,0, 4. 1666667e -3,120 // Execute on Master and trigger the slaves.
*OPC3?
// Will return 0 if not complete, Will return a 1 if execution is complete.
