Section 4: How to Control Other Instruments with the Model 4200-SCS Model 4200-SCS User Manual
The switch matrix is controlled by the 4200-SCS using the GPIB bus. Use a 7007 GPIB cable to
connect the 707 Switching Matrix to the 4200-SCS. For connection details, refer to the Reference
Manual, KI 70X Switching Matrix Properties tab, page 7-30 and Reference Manual, Test
connections for a switch matrix, page 15-13. The example below shows a 7174A matrix card
installed in slot 1 of a 707A Switching Matrix. The row-column connection scheme is used for this
tutorial.
A UTM is used to control the switch matrix. When a test sequence for a device is started, the UTM
will close the appropriate matrix crosspoints to connect the specified instrument terminals to the
appropriate test system pins. For details about UTMs, refer to the Model 4200-SCS Reference
Manual.
