Switch matrix mainframes

The 4200A-SCS provides a user library containing preconfigured data acquisition and control user
modules for the Series 700 Switch System.
You can use the 4200A-SCS with switch matrices from other vendors. However, you will need to
develop software to control these matrices from Clarius
page 8-1) for information about developing user modules and libraries.
Card installation
Refer to the instructions for your matrix card for card installation instructions.
GPIB connections
The 4200A-SCS controls the switch matrix using the GPIB interface. Connect the GPIB port of the
switch matrix to the 4200A-SCS using a 7007-1 or 7007-2 GPIB cable.

Switch matrix connections

A switch matrix enhances the connectivity of the 4200A-SCS by allowing any SMU or preamplifier
signal to be connected to any DUT pin. Typically, devices are connected to columns and instruments
are connected to rows. The following topics summarize recommended switching mainframes and
matrix cards. They also show typical connection schemes with SMUs and preamplifiers.

Typical SMU matrix card connections

The figure below shows typical SMU matrix card connections using local sensing. Note that the four
SMU FORCE terminals are connected to the matrix card rows, while the DUT HI terminals are
connected to the matrix card columns. All 12 DUT LO terminals are connected together, and the DUT
LO signal is connected to the ground unit FORCE terminal. Any SMU FORCE terminal can be
connected to any DUT HI terminal simply by closing the appropriate matrix crosspoint.
