Parameters
VdAdjust
VdAdjust sets the drain voltage automatic adjustment function ON or OFF. This
function is used to compensate the voltage drop caused by the shunt resistor. See
Figure 5-11 . When this function is OFF, the SMU applies Vd (specified drain
voltage). When this function is ON, the SMU output level will be automatically
controlled so that Vd is applied to the drain terminal.
If you do not mind the effect of the shunt resistor, set this function OFF. This brings
higher measurement throughput.
VgAdjust
VgAdjust sets the gate voltage automatic adjustment function ON or OFF. This
function is used to obtain stable gate voltage. When this function is OFF, the PGU
applies Vg (specified gate voltage). When this function is ON, the PGU output level
will be automatically controlled so that Vg is applied to the gate terminal.
If you do not mind the stability of the gate voltage, set this function OFF. This
brings higher measurement throughput.
If you set PulseBase < > 0 V, set this function ON.
To use this function, set the pulse amplitude to < 4.0 V.
