center conductors of the BNC connectors are connected to the device under test (DUT). The outer
shield of one of the coaxial cables is typically connected to a Faraday shield. The Model 4284A or
4980A output is typically connected to the wafer backside (or well). The input is typically connected to
the gate of a MOS capacitor.
