Update on Pending Major Revisions to ANSI C63.4 and the NEW ANSI C63.25.2
Join Us at a LIVE Webinar with Experts from the American National Standards Committee C63® to Learn How These Important EMC Standards Affect Your Work! All members and guests are welcome to attend, but you must register in advance.
This webinar will provide an update on the NEXT EDITION of ANSI C63.4 (Methods of Measurement of Radio-Noise Emissions from Low-Voltage Electrical and Electronic Equipment in the Range of 9 kHz to 40 GHz) and the NEW ANSI C63.25.2 (Validation Methods for Radiated Emission Test Sites, 30 MHz to 1 GHz). It is expected these two standards will be published concurrently in early 2023 - attend the webinar to learn why the concurrent publication timing is IMPORTANT.
In addition to our speakers being active technical contributors to the writing of these standards, our moderator is Daniel D. Hoolihan, Chair of ANSC C63 that develops these standards. Mr. Hoolihan is President of Hoolihan EMC Consulting. His 50 years of experience in the EMC engineering profession began at Control Data Corporation. Since January 2000, he has been consulting in EMC engineering. Mr. Hoolihan has been a member of the IEEE since 1983 and is currently a Life Senior Member. From 1998-1999 he was President of the IEEE EMC Society and has served on its Board of Directors for many years since 1987. He has held numerous leadership positions within the EMC Society and currently serves as Chair of the History Committee. Mr. Hoolihan received his MS degree in Physics from Louisiana State University in 1969 and his MBA from the University of Minnesota in 1975.

Update on ANSI C63.4:202x – The Latest Developments
For the last five years, a Working Group within Subcommittee 1, Techniques and Developments, has been working on developing the latest edition of the seminal C63 standard ANSI C63.4. Currently, the Working Group consists of 26 members representing industry and government organizations from the US and Canada. Several key changes have been implemented to align with new technologies, and some others still need to be finalized. This presentation will cover the latest status of the document and describe important changes in the next revision to ANSI C63.4 including a new definition of measurement distance, clarifications of the EUT layout and setup, the 2 dB rule, radiated emission measurements above 1 GHz, dated references, and other important considerations.

Streamlining Site Validation Measurements Below 1 GHz in ANSI C63.25.2
Normalized Site Attenuation (NSA) measurements have become a synonym for site validation measurements below 1 GHz. However, the NSA process has created confusions in the industry because a user needs to ostensibly go through an unnecessary theoretical NSA calculation. The newly proposed method in C63.25.2 removes these extraneous steps so the site validation measurement process can be reduced to either a Site Comparison Method (SCM) or a Delta NSA (DNSA) method. The SCM is similar in concept to the Reference Site Method (RSM) in the CISPR standards. The DNSA method, which is applicable to common biconical antennas, eliminates the need to go through a dipole theoretical NSA and Geometry-Specific Correction Factors (GSCF). These new approaches streamline the site validation process for below 1 GHz applications and reduce the confusion for the users of the standards. This presentation will go through the rationales and show the equivalencies of the new and the previous methods. (As of March 2022, the draft ANSI C63.25.2 standard has been approved by the C63 Main Committee. The Working Group is currently addressing comments. Provide YOUR comments at the webinar!)
