Posted Aug. 22, 2024, a Petition for Rule-Making requesting to incorporate the newly adopted ANSI/USEMCSC C63.25.2-2024 standard, rules for the validation of test sites used for radiated emission testing between 30 MHz and 1 GHz., into FCC Title 47 Part 2 and Part 15.
The C63.25 standard series will consolidate site validation methods into a standard series for reference from within various test method standards (i.e. C63.4, C63.10 etc.). The series addresses the appropriate and required site validation for sites used when performing tests related to the applicable frequency range of measurement.
C63.25.1 - Validation Methods for Radiated Emission Test Sites, 1 GHz to 18 GHz
C63.25.2 - Validation Methods for Radiated Emission Test Sites, 30 MHz to 1 GHz
C63.25.3 - Validation Methods for Radiated Emission Test Sites, 18-40 GHz
The content of C63.25.2 consists of the traditional normalized site attenuation methods used for years and the addition of two new methods, a site comparison method (SCM) and delta NSA (DNSA) method. For more information and details on the new methods see reference below or obtain a copy of C63.25.2.
