2.2 ISRT Tool Test Procedure

The ISRT tool is generally used for regulatory approval such as BT SIG/QDID, FCC ID, CE and so on. The following ISRT test procedures explain the common usage of the ISRT tool on a Windows® PC. For more details on the ISRT tool, refer to the ISRT User Manual in the ISRT tool release package.

  1. Open the ISRT tool and click CREATE to select the test solution.
