The rest of the input parameters are structured as terminal/pin pairs. Each terminal/pin pair specifies
the signal path through the matrix. For example, if the specified pin parameter for SMU1 is 4, then
SMU4 will connect to pin 4 of the test fixture or prober when the UTM is run. The pin parameter value
0 (or −1) indicates that no connection will be made.
Terminal ID: Terminal identification for the most common components used in the system
configuration are as follows:
• SMU1 to SMU4: These are the signal HI terminals for the four SMUs.
• GNDU: This is common terminal for the Ground Unit of the 4200A-SCS.
• CMTR1: This is used for a C-V Analyzer. For the 590, it is the OUTPUT terminal. For the
Keysight Model 4980A, it is the HCUR terminal.
• CMTR1L: This is also used for a C-V Analyzer. For the 590, it is the INPUT terminal. For the
Keysight Model 4980A, it is the LCUR terminal.
• PGU1: This is output HI for the Keysight Model 8110A Pulse Generator.
A test example demonstrates how this user module controls the switch matrix (see Switch matrix
control example (on page 2-30)).

You can connect the instrument terminals to one or more DUT pins. If the DUT pin number is less
than 1, then that connection is ignored (not performed), otherwise the specified instrument is
connected to the desired DUT pin. If you wish to connect an instrument to more than one DUT pin,
you may specify that instrument terminal again in the parameter list.
