Introduction

This section provides basic information on creating a PMU project in Clarius and specific information

on the options available for PMUs and PGUs.

For additional detail on working with Clarius, refer to the Model 4200A-SCS Clarius User's Manual.

Configure the PGU, PMU, and RPM using tests

To configure and control the PGU, a user test module (UTM) is needed. You can also use UTMs to

configure and control the PMU and RPM preamplifier. For UTM programming, see “LPT commands

for PGUs and PMUs” in Model 4200A-SCS LPT Library Programming.

You can use interactive test modules (ITMs) to configure and control a PMU and RPM preamplifier.

Refer to “Configure a simple test” in Model 4200A-SCS Clarius User's Manual for information on

configuring an ITM for the PMU.

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. For details, refer to

Using the

RPM as a switch (on page 2-9).

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.
