An ITM automatically controls the RPM based on the type of test (pulse, CV, SMU). RPM switching
can only be controlled using the
rpm_config
LPT function in a UTM. Refer to
(on page 2-8) for details.
For automatic switching of the RPM in ITMs, the RPM must already have all instrument cabling
connected and recognized by the system. Information on performing this update is in “Update the
RPM configuration” in
Model 4200A-SCS Setup and Maintenance
.
Step or sweep multiple device terminals in the same test
Multiple steps or sweeps in an interactive test module (ITM) must track with regard to step number
and duration. For example, you might want to apply multiple steps to multiple device terminals, such
as when stepping the biases on two transistor terminals and sweeping voltage or current on the third
terminal. In this setup, Clarius automatically sets the step operations to occur simultaneously, with
one terminal set up as the master. All other step functions are automatically designated as
subordinates. The following figure illustrates this concept.
