PLSDIV Test Definitions
PLSDIV DC IdVg SMU
VdStop Secondary sweep stop voltage for the drain terminal.
-
10 to 10
V, 4 digits or 10 mV resolution.
VdStep Secondary sweep step voltage for the drain terminal.
-
10 to 10
V, 5 digits or 1 mV resolution.
• VgStart, VgStop, VgStep
The parameters set the primary sweep source used to apply the gate voltage. The
number of sweep points is given by the following formula. Then ignore the
numbers after the decimal point.
Number of sweep points = (VgStop
-
VgStart) / 1
• VdStart, VdStop, VdStep
The parameters set the secondary sweep source used to apply the drain voltage.
The number of sweep points is given by the following formula. Then ignore the
numbers after the decimal point.
Number of sweep points = (VdStop
-
VdStart) / 1
• Gate voltage
To apply the specified voltage (Vg) to the gate terminal, the SMU output voltage
(VgSet) will be set to the following value.
VgSet = Vg * (TermR+CableR) / TermR
Extended Test
Parameters The following parameters are available to set the test condition.
IgLimit Gate current compliance, in A. 1 nA to 100 mA, 3 digits or 1 nA
resolution. Set the value that covers current to the terminator.
For example, the current is 100 mA for TermR=50
Ω
with
Vg=5 V.
Ranging Current measurement ranging mode. Auto, LimitedAuto, or
Fixed.
Irange Current measurement range. 10 pA to 100 mA. 6 digits or 10
pA resolution. Available measurement range depends on the
type of SMU.
ADCType Only for the E5260/E5270 series. Type of A/D converter.
HighSpeed or HighResolution
IntegMode Only for the E5260/E5270 series. Integration mode. Auto,
Manual, or PLC.
