4-wire remote sensing
The following figure shows 4-wire remote sense connections. The 7078-TRX-BNC is a 3-lug triaxial-
to-BNC adapter. As shown in the figure, connect the adapters to the 3-slot triaxial connectors, and
then use a 7051-5 BNC cable to make the connections to the Model 4284A or 4980A.
