Recent Advances in EMC Test Site Evaluation Using Advanced Antenna Measurement Techniques

This workshop will share the activity currently underway in the American National Standards Committee (ANSC) C63® committee for the C63.4 and C63.25 series.  Among the many updates, EMC Site Validation requirements are migrating from C63.4 to the C63.25 standards series: ANSC C63 - C63.25.1, C63.25.2, and C63.25.3. Topics covered include: (1) Review of the latest draft edition of ANSI C63.4:20xx and (2) Application of Time Domain (TD) SVSWR in C63.25.1 (1 GHz – 18 GHz) (3) Newly streamlined procedures for site validation measurements in C63.25.2 (30 MHz – 1 GHz) (4) Latest development for site validations using Cylindrical Mode Filtered SVSWR (CMF SVSWR) measurements for test site validation and antenna calibration (18 GHz – 40 GHz) to be included in C63.25.3. This workshop is designed to increase your understanding of the C63.4 standard and the expected changes in the next revision, and what to anticipate in the new C63.25 series on EMC site validation methods. The site validation test methodology above 18 GHz in C63.25.3 is under consideration for adoption by CISPR A.<br />For the C63.4 discussions, there will be an analyses and changes in the requirements for the above 1 GHz test method, use of the 2 dB rule, compliance files, test setup changes, and many other aspects.  For the C63.25 discussion, application of time domain and mode filter methods for validating EMC test sites will be presented. Time permitting, comparisons will be made to the corresponding site validation measurement techniques specified in CISPR.
