Interest in reverberation chambers has grown in the last 15 years, almost in step with the increasing complexity and, in some cases, vulnerability of electronic systems. The severity of this test environment, especially for immunity testing, is due to the inherent attributes of a well-designed chamber. There are many parameters that can be optimized to suit the type of testing to be done, ranging from the traditional EMC tests to the more recently developed sensitivity and radiated power tests performed on wireless communication devices. Mr. D’Abreu discusses the importanat aspects of the design, validation, and testing of reverb chambers, including a look at some of the pitfalls, while drawing on his years of experience in designing chamber installations for EMC and wireless applications.

Garth D’Abreu is the Director, Automotive Solutions at ETS-Lindgren based at the corporate headquarters office in Cedar Park, Texas. He currently has primary responsibility for the design and development functions within the Systems Engineering group, specializing in turnkey solutions for Automotive EMC, Wireless and OTA test integration. Some of these more complex full vehicle and ESA test chambers involve his coordination with the RF engineering team on custom components, and the certified, internal Building Information Modeling (BIM) team at ETS-Lindgren.

He is also the ETS-Lindgren subject matter expert responsible for the ongoing research and development of Reverberation chambers, GTEM cells, and supports the RF filters, EMP applications and wireless device test systems groups. Automotive EMC, Antenna Measurement, and Wireless Test Systems for modern vehicles, incorporate multiple measurement techniques and chamber combinations, for which his expertise is well suited.

Mr. D’Abreu is a Senior Member of the IEEE EMC Society and active participant in standards development as a member of the US ISO and CISPR D automotive EMC standards committees. He has over 27 years of experience in the RF industry and holds a BSc degree in Electronics & Communications Engineering, from North London University, UK.
