Figure 3: Test system using 7072 matrix cards
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.
