本标准的目的是描述ASC C63？标准要求的1 GHz至18 GHz频率范围内辐射发射测量用试验场地的验证方法。本文件中描述的现场验证要求适用于全消声室（FAR）和开放区域试验场地（OAT）以及在地平面上配置吸收器的半消声室（SAC）。注:18 GHz以上频率的现场验证方法不在本标准范围内。关于18 GHz至40 GHz的现场验证，ANSI C63第5.5.1节中的以下文本。4-2014[B4]2给出了其他ASC C63标准的一个示例条款: A.没有适用于18 GHz至40 GHz频率范围的测试现场验证要求。满足本子条款中规定的1 GHz至18 GHz要求的试验场地被视为适合在18 GHz至40 GHz的频率范围内使用。A.

The purpose of this standard is to describe validation methods of test sites used for radiated emissions 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]2 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."
