In this example, the
sweep
X
command configures SMU2 to source a voltage that sweeps from 0 V through
+14 V in 14 steps. The results of the first
sweepv
command are stored in an array called
res1
. Because
of the
clrscn
command, the data and pointers associated with the first
sweepv
command are cleared.
Then 5 V is forced to the gate, and the measurement process is repeated. Results from these second
measurements are stored in an array called
res2
.
This example gets the measurement data needed to create a graph showing the gate voltage-to-drain
current characteristics of a field-effect transistor (FET). The program samples the current generated by
SMU2 14 times. This is done in two phases: First with 4 V applied to the gate, and then with 5 V applied.
The gate voltages are generated by SMU1.
