Model 4200A-SCS Parameter Analyzer Reference Manual

Details
This user module allows you to control a switch matrix. The default input parameters are shown in the
following figure. Typically, OpenAll (line 1) is set to 1 to initially open all connections. If set to 0, the
present connections are not affected.
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
(on page A-30)).
