ANSI C63.4 describes the United States standard procedures for measuring RF signals and noise generated by electronic and electrical instruments over the frequency range of 9 kHz to 40 GHz. ANSI C63.4 does not include either generic or product-specific emission limits. The specifications within ANSI C63.4 are harmonized with separate national and international standards utilized with similar intent. ANSI C63.4 is designed to standardize the implementation of emissions testing concerning compliance requirements intended to protect communications services. The standard can be applied to the emissions monitoring of a variety of devices, including both stand-alone units and interconnected units. Notwithstanding other possible uses, this standard is intended to be used for making emission measurements of unintentional radiators (including digital devices and receivers) and for making emission measurements of the digital device portions contained in or used in intentional radiators.
