ANSC C63® Workshop Addresses Changes to C63.4, the NEW C63.25 Series Standards, and the Recently Published C63.2
Hands-On Workshop Comes to Phoenix
August 2 and 3
CEDAR PARK,
Texas, July 11, 2024 – Active technical contributors to the American National
Standards Committee (ANSC) C63 (Electromagnetic Compatibility) will present in
the annual Summer ANSC C63 Workshop held immediately prior to the 2024 IEEE
International Symposium on Electromagnetic Compatibility, Signal and Power
Integrity (EMC+SIPI). This year’s C63
Workshop will be held August 2 and 3 at Compliance Testing in Mesa, Arizona;
the IEEE EMC+SIPI Symposium will be held at the Phoenix Convention Center from
August 5 to 9. The C63 Workshop
instructors include industry experts Cisco Systems’ Andy Griffin, C63.4 Working
Group Chair and Chair of C63 Subcommittee 1 (SC1), Techniques and Development;
ETS-Lindgren’s Zhong Chen, Vice Chair of ANSC C63 and C63.25.1 Working Group
Chair; and Rohde & Schwarz’ Jens Medler, C63.2 Working Group Chair. Standards C63.2, C63.4, and C63.25 are
developed and maintained by SC1.
The C63 Summer
Workshop provides an overview of the changes planned for the next edition of
the seminal 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” as well as the new ANSI C63.25 series of standards for EMC test site
validation. The series incorporates
C63.25.1 “Validation Methods for Radiated Emission Test Sites, 1 GHz to 18
GHz,” which includes the application of Time Domain (TD) and Site Voltage
Standing Wave Ratio (SVSWR); new procedures for site validation measurements in
C63.25.2 (30 MHz to 1 GHz); and a novel technique using Cylindrical Mode
Filtered SVSWR (CMF SVSWR) measurements for test site validation and antenna
calibration from 18 GHz to 40 GHz contained in the draft standard C63.25.3. NEW this year – an update will be provided on
the recently published C63.2 “Specifications of Electromagnetic Interference
and Field Strength Measuring Instrumentation in the Frequency Range 9 kHz to 40
GHz.”
This C63
Workshop is designed to increase one’s knowledge of the C63.4 standard, the
expected changes in the next revision, and the anticipated EMC site validation
methods in the new C63.25 series. Using
the 3-meter semi-anechoic chamber at Compliance Testing, attendees will
participate in a live demonstration using CMF SVSWR measurements for test site
validation and antenna calibration (18 GHz to 40 GHz) to be included in
C63.25.3.
Among the many
updates presented in the C63 Workshop, EMC site validation requirements are
migrating from C63.4 to the C63.25 standards series: ANSI C63.25.1, C63.25.2,
and C63.25.3. For the C63.4 discussions,
there will be an analysis of 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 also be presented along with a live demonstration on its
usage.
ANSI C63.25.3 is
particularly significant since the standard provides the latest test
methodology for validating performance of an EMC test site in the frequency
range of 18 GHz to 40 GHz, the natural evolution of measurements for the C63.25
standard series since the publication of standards ANSI C63.25.1 and C63.25.2. “This is a new frequency range to explore for
EMC test sites. A standard in this
frequency range currently does not exist, yet industry demand for testing
products at higher frequencies is increasing,” said Zhong Chen, Chief Engineer
with ETS-Lindgren and Vice Chair of the C63 Committee. “C63 is addressing this industry-driven
challenge with the new draft standard C63.25.3.
Our goal is to provide a site validation measurement technique that is
relatively easy and fast to perform and, most importantly, yields results that
are reliable and repeatable.”
A hallmark of
the draft C63.25.3 standard is the new capability to provide greater
information beyond the basic chamber reflection levels. “The current SVSWR standard method under-samples
data collection and offers no information on the coverage of the receive
antenna; only at a few positions within the quiet zone are evaluated. In contrast, the CMF SVSWR method specified
in C63.25.3 provides a comprehensive view of the chamber reflection levels as
well as the quality of the entire quiet zone, all with a faster test time
compared to the traditional SVSWR method,” offered Mr. Chen.
In light of the
significance of the draft C63.25.3 standard in expediting EMC test site validation
time as well as offering greater performance diagnostics, Mr. Chen and Yibo
Wang, RF Engineer with ETS-Lindgren, have produced a video demonstration of the
CMF SVSWR method, now available here,
to educate test lab operators and managers on this novel technique. The video shows the entire measurement
process, including the post-processing, which can be performed in real time.
