(double) The current compliance for the pulse source on the DUT Drain. This
supplied value is used to calculate the maximum voltage to source to the
DUT, based on a default 50 Ω DUT load. The compliance can be used to
protect the DUT.
(int) Determines whether to use load line correction to compensate for the
voltage drop caused by the DUT impedance on the Gate. When load line
correction is on (1), the test will start by assuming a high impedance value for
the device and will approach the correct bias and pulse values over a series
of pulses, that ensures that the sourced pulses match the requested values.
When load line correction is turned off, the specified voltages will be sourced
(1 = Use Load Line, 0 = No Load Line).

(double) The max current allowed for the DUT Gate, for both DC and pulse
sweeps. If the Gate current becomes greater than MaxIg, the present sweep
will stop and the test will continue with the next Vg step.
(double) The max current allowed on the DUT Drain, for both DC and pulse
sweeps. If the Drain current becomes greater than MaxId, the present sweep
will stop and the test will continue with the next Vg step.
(double) The max power allowed to the DUT Gate. If the Gate power
becomes greater than the MaxPowerGate, the test will exit.
(double) The max power allowed to the DUT Drain. If the Drain power
becomes greater than the MaxPowerDrain, the test will exit.
(char*) String representing the ID for the SMU connected to the gate.
(char*) String representing the ID for the SMU connected to the drain.
(char*) String representing the ID for the PG2 connected to the gate.
(char*) String representing the top VPU on the 4205-PCU. This is the card on
the right (or the card with the lower ID number), when facing the back of the
system.
(char*) String representing the bottom VPU on the 4205-PCU. This is the card
on the left (or the card with the higher ID number), when facing the back of the
system.
(int) Sizes of the output arrays. All arrays should be the same size
and need to be large enough to hold all sweep points.
(int) Turns on real time graphing (1 = Real Time Graphing, 0 = No Real Time
Graphing).
(double) Array of measured drain voltage values.
(double) Array of measured drain currents.
(double) Array of programmed gate voltages.
(double) Array of measured gate currents.
