Wednesday, June 16, 2021 8:00 am – 9:00 am PDT Optimizing EMC and RF Test Chamber Design and Performance By Zhong Chen, Director of RF Engineering, ETS-Lindgren, Cedar Park, TX Abstract: An EMC test chamber is a considerable investment impacted by many factors, a few of which include performance, space limitations, features, and budget. Most often the budget drives a series of tradeoffs between the size of your quiet zone, partial absorber linings, and performance. In the real-world, one rarely encounters a "standard" chamber, thus some customization is inevitable. How do you lower the risk of a chamber not meeting your expectations? In this presentation, we provide an overview of the EMC chamber design process and highlight the importance of an accurate EMC chamber simulation tool in meeting challenging design requirements. Case studies of four very different chambers will be shown, including predicted and validated performance data. Participants will gain a better appreciation of the technical challenges, limitations, speed, accuracy, and tradeoffs among the different simulation techniques. The presentation will also benefit those who wish to refurbish an existing chamber, those who have a chamber that struggles to meet site requirements and want to diagnose/correct the problem, and those who want to understand how a chamber impacts measurement uncertainties. A great deal of advancements have been made in chamber modeling software; with an understanding of the tools available, you can optimize your existing and planned chambers. SPEAKER BIOGRAPHY

Originally Broadcast on May 26 Emerging Millimeter Wave Radiated Emissions Test Methods: Lessons Learned By Ross Carlton, Chair, ANSI C63 Subcommittee 3 on International Standardization EMC Test Systems Engineer, ETS-Lindgren, Cedar Park, Texas Abstract: While mmWave communication technology has been used extensively for decades, this was largely confined to government or military applications. Today, mmWave devices are increasingly prevalent for commercial applications with the proliferation of personal wireless devices. With the new 5G technology, how are these devices regulated to ensure performance as intended? As EMC engineers, we are familiar with the significant problems RF interference may cause due to poorly designed and/or tested products. In this presentation, we will begin with a review of the emerging radiated emissions test methods for mmWave devices intended for use in the United States and governed by the requirements of the FCC's Part 30 of the Code of Federal Regulations. These test methods are included in the ANSI C63.26 standard for licensed transmitters to document compliance with FCC requirements. The standard outlines test methods for measurement of radiated and conducted emissions, RF power, out-of-band emissions, frequency stability, and other regulatory requirements for a variety of devices. Since its publication in 2015, mmWave technology has advanced significantly. The presentation includes a discussion of the currently available methods, including their benefits and constraints. Proposed changes to the next edition of C63.26 currently underway will be reviewed. Time permitting, an experiment will be performed to characterize and validate aspects of the measurements methods.
