This example gathers data to create a graph showing the common drain-source characteristics of a
field-effect transistor (FET). A fixed gate-to-source voltage is generated by SMU1. A voltage ramp from 0 V
to 5 V is generated by SMU2. Drain current applied by SMU2 is measured 11 times by the smeasi
command. Data is stored in the array resi.
