Source Isolation Utility

This test applies to the following models:

The purpose of this utility is to verify that the RF shielding is functioning properly following a repair.

This measurement is essentially two DANL measurements. The first step measures the DANL with the source off, and the second with the source on. The difference between the two DANL measurements is the source isolation. The test results are saved in a text output file. See the troubleshooting link below for information on accessing the text output file.
