Insights into the New EMC Test Site Validation Requirements in ANSI C63 Standards
Site validation requirements are being consolidated into the ANSI C63.25 series of standards within the American National Standards Committee (ANSC). Some important changes and updates are reflected in the recently published ANSI C63.25.1, soon to be released C63.25.2, and ongoing work in the C63.25.3 working group. This presentation will provide insights into the development efforts and rationale behind these recent changes. The discussion will contain three topics, based on the three frequency ranges (below 1 GHz, 1-18 GHz, and 18-40 GHz), as is divided by the three C63.25 standards. We will go over the evolutions of the NSA method to the Site Comparison Method (SCM) and Delta NSA (DNSA) method in C63.25.2 (< 1 GHz), the CISPR SVSWR to Time Domain SVSWR in C63.25.1 (1-18 GHz), and the recently developed Cylindrical Mode Filtered SVSWR in C63.25.3 (18-40 GHz). Attendees will gain a deeper understanding of the technical background (the whats and whys) for site validation methods, which should help with the preparation for the upcoming changes to ANSI C63.4 and ANSI C63.5. The site validation currently specified in these industry flagship standards will be removed; instead, C63.4 and C63.5 will include a reference to the C63.25 family of standards for the new site validation test methods.
Biography:
Zhong Chen is the Director of RF Engineering with ETS-Lindgren, located in Cedar Park, Texas. He has over 25 years of experience in RF testing, anechoic chamber design, as well as antenna and EMC field probe design and measurements. He is currently a member of the Antenna Measurement Techniques Association (AMTA) Board of Directors. Mr. Chen is the Chair of Subcommittee 1 of ANSC C63, which is responsible for EMC antenna calibration and test site validation standards. He is also chair of the IEEE Standard 1309 committee responsible for developing calibration standards for field probes, and IEEE Standard 1128 for absorber measurements. He has served as a Distinguished Lecturer for the IEEE EMC Society. His research interests include measurement uncertainty, time domain measurements, and development of novel RF absorber materials. Mr. Chen received his M.S.E.E. degree in Electromagnetics from the Ohio State University at Columbus.

LIVE DEMO! Cylindrical Mode Filtered SVSWR: A New ANSI C63 Method Proposed for EMC Site Validation 18 GHz to 40 GHz
The Cylindrical Mode Filtered SVSWR (CMF SVSWR) is measured by placing the transmit antenna (typically a low gain omni-directional antenna) at the edge of the turntable, and performing a single cut vector pattern measurement. The vector S21 as a function of turntable angle at each frequency is transformed to the spectrum domain, where a filter can be applied to mathematically remove the chamber effects. The SVSWR is derived by comparing the original pattern in the chamber to the “clean” filtered pattern. This CMF SVSWR provides a more comprehensive evaluation of EMC chamber quiet zone, and can be readily measured without any special positioning fixtures. The demonstration will show an entire measurement process including the post processing which can be performed in real time. This new measurement technique is under consideration for the new draft standard ANSI C63.25.3 in development by the ANSC C63® committee for EMC test sites from 18 GHz to 40 GHz.
