Scope
The purpose of this standard is to describe validation methods of test sites used for radiated emission measurements in the 1 GHz to 18 GHz frequency range as required by ASC C63? standards. The site validation requirements described in this document are applicable to fully anechoic rooms (FAR) and open area test sites (OATS) as well as semi-anechoic chambers (SAC) that are configured with absorber on the ground plane. NOTE??Site validation methods for frequencies above 18 GHz are outside the scope of this standard. Concerning site validation for 18 GHz to 40 GHz@ the following text from 5.5.1 of ANSI C63.4-2014 [B4] 1 gives an example provision from other ASC C63? standards: ??There are no test site validation requirements applicable to the frequency range of 18 GHz to 40 GHz. A test site that satisfies the requirements stated in this subclause from 1 GHz to 18 GHz is deemed to be suitable for use over the frequency range of 18 GHz to 40 GHz.??
