Two SMUs connected to a 3-terminal device (local sense)
shows how to use three SMUs to test the same 3-terminal device. The
third SMU is connected to the source (S) terminal of the JFET. This allows the
source terminal to be biased above signal low. Setting this SMU to output 0V
effectively connects the source terminal of the JFET to signal low.
