Multiple SMU connections

Figure 3-8
typical application is for SMU B to source a range of gate voltages, while SMU A sources voltage
to power the device and measures current at each gate voltage.

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.
