Indicators
When the RPM is operational in a 4200A-SCS system, an LED on top of the RPM illuminates. The color of the
LED indicates which instrument is connected to the DUT during a test. Use the color codes in the following
figure to determine which instrument is connected. Note that the instrument indicator does not show that a test
is running or that the output of an instrument is active. To determine if a test is running, check the status in
Clarius.

Model 4200-PRB-C, 4200 Pulse SMA to SSMC Adapter (PA-928): This document provides information on
the 4200-PRB-C cable that is provided with the 4225-PMU and used by the PMU as well as the RPM
modules.

Switching and connections
Both modules allow for automatic switching between dc I-V, C-V, and pulsed I-V measurements when executed
in ITM tests. The following topics describe typical connections for these measurements.
When properly installed, you can perform different electrical measurements on the device without having to
disconnect and reconnect cabling for each test. Optional multi-measurement performance cable kits
(Model 4210-MMPC) are available to connect the 4200A-SCS to a prober manipulator. In addition to eliminating
the need for re-cabling, these kits help maximize signal fidelity by eliminating the measurement errors that often
result from cabling errors.
Turn off system power before connecting or disconnecting the RPM to or from the PMU.
Failure to do so may result in PMU or RPM damage, possibly voiding the warranty.
