- Figure 4. An illustration of the power system components that generate common mode current, as well as the isolation capacitances that support AC currents generated externally
- Figure 5a. With a single SMU, grounding the DUT, either directly or through a capacitance, can channel ground current into the measurement LO lead
- Figure 5b. In this single SMU application, grounding LO at the DUT, either directly or through a capacitance, leads to no error currents in the measurement LO lead
- Figure 5c. With a single SMU, grounding the shield with a resistor, at the instrument leads to no error current in the measurement LO lead
- Figure 5d. With two SMUs, the remote sense lines compensate for the current flowing in the measurement leads generated from the use of two different grounds
