IEEE/ANSI C63.2-2016 – American National Standard for Specifications of Electromagnetic Interference and Field Strength Measuring Instrumentation in the Frequency Range 9 kHz to 40 GHz has been released. This standard, which was developed by the Accredited Standards Committee C63®—Electromagnetic Compatibility, specifies guidelines for measuring receivers (electromagnetic interference (EMI) receivers and spectrum analyzers with and without preselection) used for radiated and conducted emission measurements.
IEEE/ANSI C63.2-2016 actually has its origins long ago, back during World War II. At the time, the needs of the armed forces for instruments and methods for radio-noise measurement were critical, so a special subcommittee of ASA (American Standards Association, former name of the American National Standards Institute), Sectional Committee C63, Radio-Electrical Coordination, developed a wartime specification that became the joint Army-Navy Specification JAN-I-225 and was issued in 1945.
It was soon after approved as American War Standard—Method of Measuring Radio Interference of Electrical Components and Completed Assemblies of Electrical Equipment for the Armed Forces from 150 kc to 20 Mc, C63.1-1946. In 1950, the ASA Sectional Committee C63 completed the American Standard Specifications for a Radio Noise Meter, 0.015 to 25 Mc/s, C63.2. Throughout the remainder of the Twentieth Century, this standard underwent many updates to keep it current and more compatible with international standards.
The new revision, IEEE/ANSI C63.2-2016, is meant to consolidate the recommendations found in CISPR 16-1-1:2010 and ANSI C63.2 into one standard. This harmonizes the two standards’ specifications so that the same instrument can be used for measurements in accordance with national and international standards. In addition to this alteration, the standard possesses some changes added to address domestic measurement needs, and it now covers the frequency range 18 GHz to 40 GHz.
The standard’s content is presented in tables, which specify test instruments. This information is covered in the IEEE/ANSI C63.2-2016 document.
