Section 8: Use the 4200A-CVIV Multi-Switch
Model 4200A-SCS Parameter Analyzer User's Manual

8. A dialog box is displayed with instructions to remove the device-under-test (DUT) from the test
fixture or lift the probes before performing open compensation. Remove the DUT before selecting
OK
.
9. Return the DUT to the test fixture when compensation completes.
10. In the project tree, clear the check box next to the
cvu-cviv-comp-collect
action.
Clearing this action alerts the software to not perform the compensation collection if the whole
project is executed. It is not necessary to collect compensation constants each time the test is
executed. To collect the compensation constants again, select the action and its check box in the
project tree, then select
Run
.
The compensation constants are stored in a database that links each 4200A-CVIV configuration to a
set of compensation values. These values are recalled if compensation is enabled in a CVU test while
using this 4200A-CVIV configuration.
For optimal results, the compensation collection action must be executed for every 4200A-CVIV
configuration that is used throughout the test sequence.
