Triaxial connectors
Adapters are required to connect the 590 to equipment (for example, a probe station, test fixture, or
matrix card) that uses triaxial connectors. The 7078-TRX-BNC is a 3-lug triaxial to BNC adapter. As
shown in the following figure, connect the adapters to the 3-slot triaxial connectors and then use a
7051 BNC cable to make the connections to the 590.
See Using Switch Matrices (on page A-1) for details on using a switch matrix with the 590 C-V
Analyzer.

GPIB connections
The 4200A-SCS controls the 590 through the General Purpose Interface Bus (GPIB). Use the 7007-1
or 7007-2 GPIB cable to connect the GPIB of the 590 to the GPIB of the 4200A-SCS.
