GateRange double The voltage measure range for the scope channel measuring the Gate.
Use 0 for scope autoranging, or specify a voltage value for a fixed
range. Valid voltages are 0.050, 0.1, 0.2, 0.5, 1, 2, 5, 10.
DrainRange double The voltage measure range for the scope channel measuring the Drain.
Use 0 for scope autoranging, or specify a voltage value for a fixed
range, where V = I * 50
Ω. Valid voltages are 0.050, 0.1, 0.2, 0.5, 1, 2, 5,
10.
LoadLineCorr int Determines whether to use load line correction to compensate for the
voltage drop caused by the 50 Ω sense resistor used to measure the
drain current (Id).
1 = load line correction active.
0 = no load line correction.
VPUID char * The instrument ID. This should be set to VPU1 for 4200 systems with
the 4200-PIV package.
GateSMU char * The SMU used for the Gate. This can be SMU1 up to the maximum
number of SmUs in the system.
DrainSMU char * The SMU used for the Drain. This can be SMU1 up to the maximum
number of SmUs in the system. This is the SMU that applies the DC
bias to the DUT drain during the sweep.

VgProgSize
VdMeasSize
VdProgSize
int Set to a value that is at least equal to the number of steps in the sweep
and all five must be the same value.
