FCC Equipment Authorization Rules NPRM Recently Released for ANSI C63.25.1: Validation Methods for Radiated Emission Test Sites, 1 GHz to 18 GHz and ANSI C63.10: Procedures for Compliance Testing of Unlicensed Wireless Devices

Attend a Webinar with Industry Experts on Thursday, February 24, to Learn How These Standards Impact EMC and Wireless Test Chambers


CEDAR PARK, Texas, February 17, 2022 – With the recent release of the FCC Equipment Authorization Rules NPRM for standards ANSI C63.25.1 and ANSI C63.10, new attention is being paid to the FCC’s pending acceptance of these novel standards.  ANSI C63.25.1 in particular is significant since it is a new standard that provides the latest test methodology for validating performance of an EMC test site.  Using the time domain measurement technique described in the standard, users can validate their test site quickly and accurately.  The technique correlates to the conventional CISPR SVSWR method and offers an important bonus in that it can be used as a chamber “debugging” tool to detect the performance problem areas in an EMC chamber.  ANSI C63.10-2020 is an update to the previous edition published in 2013.  With the explosive growth in wireless devices, test requirements and methods have advanced tremendously as documented in the latest edition of this prominent wireless device test standard.

In light of the significance of these standards to users of commercial and in-house EMC and wireless test chambers, experts from the American National Standards Committee (ANSC) C63 (Electromagnetic Compatibility) will deliver an educational webinar to present the new test requirements for FCC approval.  In addition, an advance preview of the changes expected for the next edition of ANSI C63.26 “Procedures for Compliance Testing of Licensed Transmitters” will be provided during the webinar.  The changes are considerable since the prior edition of this standard was published in 2015.

The webinar moderator is ANSC C63 Committee Chair Dan Hoolihan with Hoolihan EMC Consulting.  Webinar speakers, Zhong Chen with ETS-Lindgren and Bob DeLisi with UL LLC, are active technical contributors to the standards published by ANSC C63.  Their presentation topics are:

·       Time Domain SVSWR for Compliance Site Validation Measurements Based on ANSI C63.25.1-2018 by Zhong Chen, Director of RF Engineering, ETS-Lindgren, Cedar Park, Texas; Chair of ANSC C63 Subcommittee 1: Techniques and Development


·       Update on Unlicensed and Licensed Wireless Device Standards ANSI C63.10-2020 and Draft C63.26 by Bob DeLisi, Principal Engineer, UL LLC, Melville, New York; Chair of ANSC C63 Subcommittee 4: Wireless and ISM Equipment Measurements


Mr. Hoolihan will moderate a live Q&A session with the speakers following the presentations.  More information on the webinar, including presentation abstracts, speaker biographies, and the registration link, is available here.  Download the FCC ANSI C63 standards documents C63.25.1 and C63.10 in your choice of format: FCC-22-3A1.docxFCC-22-3A1.pdf, or FCC-22-3A1.txt.
