Line
2
Defines the file name used for saving the result data.
4
Resets the B2961B/B2962B.
6 to 11
Sets the voltage sweep output function. And sets the sweep output from 0 to 0.1 V in 0.02 V
step (5 points).
14 to 16
Sets the current measurement function. And sets the aperture time to 0.1 PLC and the current
limit (compliance) value to 0.1 A. Auto range is ON with the default setting.
