(d) When the measurement method used requires the testing of radiated emissions on a validated test site, the site attenuation must comply with either: the requirements of ANSI C63.4a-2017 (incorporated by reference, see § 2.910) or the requirements of sections 5.4.4 through 5.5 of ANSI C63.4-2014 (incorporated by reference, see § 2.910).

(1) Measurement facilities used to make radiated emission measurements from 30 MHz to 1 GHz must comply with the site validation requirements in either ANSI C63.4a-2017 or ANSI C63.4-2014 (clause 5.4.4);

(2) Measurement facilities used to make radiated emission measurements from 1 GHz to 18 GHz must comply with the site validation requirement of ANSI C63.25.1-2018 (incorporated by reference, see § 2.910);

(3) Measurement facilities used to make radiated emission measurements from 18 GHz to 40 GHz must comply with the site validation requirement of ANSI C63.4-2014 (clause 5.5.1 a) 1)), such that the site validation criteria called out in CISPR 16-1-4:2010-04 (incorporated by reference, see § 2.910) is met.
