System Mode Smu Default Settings - Keithley 4200A-SCS Reference Manual

Model 4200A-SCS Parameter Analyzer Reference Manual

System Mode SMU default settings

When KXCI mode is started, the SMUs are in a default state that mimics the Keysight Model 4145B,
as shown in the channel definition and source setup tables below. This means that each SMU is
active and part of the test, whether or not the test used all the SMUs in the 4200A-SCS chassis.
This may be undesirable, as many tests use a different number of SMUs or SMUs in a different state
from the Keysight 4145 default. To avoid the complication of building a KXCI test starting with the
default setup, use the following commands to remove the SMUs from the setup:
DE CH1 CH2 CH3 CH4 VM1 VM2 VS1 VS2
The above shows the method for a system with eight SMUs. A system with only four SMUs would not
require the last four definitions:

* If there are less than eight SMUs, only the SMUs in the chassis
are programmed to the defaults shown.
