Figure 74: PMU IV sweep Help pane description
This user module allows for an optional SMU to dc bias a transistor bulk while performing a pulse I-V
sweep with a 4225-PMU and optional 4225-RPM. However, due to system restrictions, this SMU
must not be connected to the test device through the 4225-RPM (an error results).
This example test is configured to use SMU1. SMU1 is connected through RPM1 of the system.
1. Set the SMU_ID from NONE to SMU1.
2. Select Analyze and view the Messages area at the bottom of the screen for error messages. For
example, if you get a message indicating "forcev(): Cannot force when not connected," you can
check the Return Values in the Help pane for more troubleshooting information (see following
figure). Note that value -233 indicates, "Ensure that the specified SMU is not connected through
or associated with an RPM. If all SMUs are associated with RPM modules, choose NONE to
permit the test to run."
