Model 4200A-SCS Parameter Analyzer Reference Manual Appendix A: Using switch matrices
7174A Low Current Matrix Card
The 7174A provides high quality, high performance switching of I-V and C-V signals. This matrix card
uses 3-pole switching (HI, LO, Guard) with 10 fA typical offset current. The card is equipped with 3-
lug triax connectors for signal connections.
The following figures show test systems using 7174A matrix cards. The supplied triaxial cables
connect the 4200A-SCS directly to matrix rows. The other instruments in the system are fitted with
BNC connectors that require the use of BNC-to-triaxial adapters.
7174A connections for local sensing
The following figure shows a system that uses local sensing. Note that coaxial tees are used to adapt
the Keysight 4284A C-V meter for two-terminal operation.
