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.
Figure 4: Test system using 7174A matrix cards
7174A connections for remote sensing
The following figure shows how to connect instrumentation for remote sense operation. Since there
are not enough matrix rows, the instruments are connected to the matrix columns. In this
configuration, two switch relays are closed to complete a path from an instrument to a device under
test (DUT). With five DUT matrix cards installed in a Series 700 Switching System mainframe, up to
30 DUT pin-pairs can be used.
