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 functions for
PGUs and PMUs (on page 13-91).
You can use interactive test modules (ITMs) to configure and control a PMU and RPM preamplifier.
Refer to Configure a test (on page 6-13
) 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 (on page 13-124) LPT function in a UTM. Refer to
Using
the RPM as a switch (on page 5-8) 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 (on page 7-10).
PMU pulse timing preview
Before executing a test, you can preview a waveform generated using the settings. This can help you
understand the behaviors of the various test settings without applying signals to the test device. The
Pulse Timing Preview is in the PMU Advanced Test Settings dialog box. An example is shown in the
next figure.
