Update preamplifier, RPM, and CVIV Configurations
After adding or removing a preamplifier, RPM, or 4200A-CVIV, you must update the system by
selecting the Update Preamp, RPM, and CVIV Configuration option.
Update the preamplifier configuration
For more information on adding or removing preamplifiers, refer to Connections and configuration (on
page 2-1).
To update the preamplifier configuration:
1. Remove or reconnect a preamplifier to the SMU.
2. Select the Update Preamp, RPM, and CVIV Configuration option.
3. Select Save.
Update the RPM configuration
The KCon feature Update Preamp, RPM, and CVIV Configuration must be run:
• Whenever an RPM is connected or disconnected from the 4200A-SCS
• Whenever RPM input connections for a SMU, CVU, or PMU are changed
When using interactive test modules (ITMs) for DUT testing, you can configure RPM switching in
KCon. After you connect the PMU, SMUs, and CVU to the RPM, update the RPM configuration in
KCon. When you then open Clarius, the system will detect the instrument connections to the RPM.
When an ITM is run, Clarius will automatically close the appropriate switches to connect the PMU,
SMU, or CVU to the output of the RPM. Use the following procedure to configure RPM switching:
For more information on adding or removing RPM connections, refer to Model 4225-RPM (on page
5-
6).
To update RPM configuration:
1. Turn off system power.
2. Disconnect line power.
3. Connect the correct RPM to the correct PMU channel.
4. If the system contains SMUs: Connect any SMU to any RPM using either one or two triaxial
cables. Repeat for all RPMs in the system.
5. If the system contains a CVU: Connect CVU High to one RPM, and CVU Low to the other RPM.
6. Turn on the system power.
7. Start KCon.
8. Select the Update Preamp, RPM, and CVIV Configuration option.
9. Select Save.
10. Exit from KCon.
If you are using an interactive test module (ITM) for testing, the RPM automatically selects the PMU,
SMU, or CVU. If you are using a user test module (UTM), you must select the correct RPM settings.
See Control RPM switching (on page 5-9
) for more information.
