Outputs for Vgid_DC_Pulse_pulseiv
Output
Type
Description
DrainI_DC/Pulse
double
The measured drain current from channel 2 of the 4200-SCP2 or the
DrainSMU. In the case of Pulse, this current is determined by
measuring the voltage drop across the 4200-SCP2 50
Ω
termination, giving Id = Vd / 50
Ω
.
DrainVMeas_DC/Pulse double
The measured drain voltage from channel 2 of the 4200-SCP2 in the
case of pulse and the measured voltage on the DrainSMU in the
case of DC.
DrainV_Prog_DC/
Pulse
double
The programmed drain voltage, either supplied by the pulse card or
the SMU for the drain.
GateVMeas_DC/Pulse
double
The measure gate voltage from channel 1 of the 4200-SCP2 in the
case of pulse and the measured voltage on the GateSMU in the
case of DC.
GateVProg_DC/Pulse
double
The programmed gate voltage, either supplied by the pulse card or
Gate SMU.
