Test Parameters
The following parameters are available to set the source output.
PulseWidth Pulse width of PGU output pulse. 10 ns to 1
μ
s, 4 digits or 1 ns
resolution. See “Parameters” on page 5-31.
VgStart Secondary sweep start voltage for the gate terminal.
PGU output.
- 4.5 V to 4.5 V, 4 digits or 10 mV resolution.
VgStop Secondary sweep stop voltage for the gate terminal.
PGU output.
- 4.5 V to 4.5 V, 4 digits or 10 mV resolution.
VgStep Secondary sweep step voltage for the gate terminal.
PGU output. 10 mV to 4.5 V, 4 digits or 10 mV resolution.
PulseBase PGU output baseline voltage.
-
4.5 V to 4.5 V, 4 digits or 10
mV resolution. See “Parameters” on page 5-31.
VdStart Primary sweep start voltage for the drain terminal. SMU output.
-
10 V to 10 V, 5 digits or 1 mV resolution.
VdStop Primary sweep stop voltage for the drain terminal. SMU output.
-
10 V to 10 V, 5 digits or 1 mV resolution.
VdStep Primary sweep step voltage for the drain terminal. SMU output.
-
10 V to 10 V, 5 digits or 1 mV resolution.
• VdStart, VdStop, VdStep
The parameters set the primary 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
• VgStart, VgStop, VgStep
The parameters set the secondary 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
Pulse amplitude must be > 55 mV and < 4.5 V. So |VgStart
-
PulseBase| and
|VgStop
-
PulseBase| must be > 55 mV and < 4.5 V.
To use the gate voltage automatic adjustment function, set the pulse amplitude to
< 4.0 V.
