Speakers
Mr. D'Abreu of ETS-Lindgren, Cedar Park, Texas
Meeting the Need for Hardware-in-Loop (HIL) Type Enhanced EMC Full Vehicle Measurements
Traditional EMC measurements were developed based on protecting the licensed spectrum from interference caused mainly by ignition systems. Things have moved a long way from these early sources and with the proliferation of digital control systems and electric drives, there are many more on board noise sources and even more potential vulnerabilities. Modern commercial and military vehicles are now fitted with an increasing number of advanced driver assistance systems (ADAS) many of which rely on external sensors. The EMC of these systems is vital in ensuring that safety is not compromised. This presentation will discuss some of the test and measurement trends that are developing to address this emerging need. A review of some of the chamber types with their advantages for these diverse applications will be provided.
Biography:
Garth D’Abreu is the Director, Automotive Solutions at ETS-Lindgren based at the corporate headquarters office in Cedar Park, Texas. He has primary responsibility for the design and development functions worldwide within the Systems Engineering group, specializing in turnkey solutions for Automotive EMC and Wireless test integration. Some of these more complex full vehicle and electronic sub-assembly (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. Due to his considerable industry experience, he is the ETS-Lindgren global subject matter expert responsible for the ongoing research and development of Automotive EMC / Wireless test chambers for Regular, Electric and Hybrid Electric Vehicles, focusing on combination anechoic chambers, reverberation chambers, GTEM cells, EMP protection applications and wireless device test systems. Mr. D’Abreu is a member of the IEEE EMC Society and active participant in standards development, including the SAE, ISO and CISPR D automotive EMC standards, with over 25 years of experience in the RF industry. He holds a BSc degree in Electronics & Communications Engineering, from North London University, UK
Dr. Young of MITRE Corporation
An Overview of RF Measurement Applications
This presentation will highlight some of the basic RF measurement skills introduced in the CU Denver ELEC 4423 Radio Frequency Laboratory. Projects in the lab include measurements of waveguide devices, time-domain techniques, characterization of filters and amplifiers, and scattering parameters (S-parameters). Applications of measurement techniques covered in the lab will be discussed as motivation for the value and necessity of measurements when evaluating RF device and system performance. The presentation will also cover the recent addition of electromagnetic reverberation chamber capabilities as part of the curriculum, which introduces the students to relatively new approaches to evaluating wireless device performance beyond traditional EMC exposure testing. Some differences in the process and potential applications between measurements in a reverberation chamber and an anechoic chamber will be highlighted.
Biography:
Dr. William Young received a MS from Washington State University, Pullman in 1998 and a Ph.D. from the University of Colorado, Boulder in 2006, both in electrical engineering. Dr. Young’s diverse technical background includes applications of electromagnetic theory, information security, and RF interference analysis. At Sandia National Laboratories, between 1998 and 2003, his contributions included the design, validation testing, and accreditation of the communication systems for the U.S. Space Command’s Mobile Consolidated Command and Control Centers. He also led and participated in information security assessments of Critical Infrastructure communication systems for multiple government entities, including the Department of Defense, the Defence Science Organisation in Singapore, and the Bureau of Reclamation. Selected for the Sandia Doctoral Studies Program in 2003, his research, under the direction of Dr. Ed Kuester at the University of Colorado and in collaboration with NIST, focused on optimizing RF propagation from ad hoc wireless arrays and characterizing RF penetration of large buildings. Through 2006 to 2010 at Sandia, he led an investigation of electromagnetic interference on wireless technology used in space-borne telemetry applications, and researched the application of MIMO channels for perimeter intrusion detection. From 2010 to 2018, Dr. Young worked at NIST where he developed radiated test methods for evaluating the RF performance of wireless communication devices, including the application of electromagnetic reverberation chambers and real-world RF environment statistics for the National Fire Protection Association (NFPA) Electronic Safety Equipment Committee. He was a key technical contributor to the NFPA 1982: Standard for RF Personal Alert Safety Systems (PASS), and the ANSI C63.27 - Standard for Evaluation of Wireless Coexistence, published in May 2017. From 2016 to 2018, he served as the Group Leader for Shared Spectrum Metrology in the NIST Communications Technology Laboratory. During that period, he also served as the technical lead for the National Advanced Spectrum and Communication Test Network project investigating LTE impacts on GPS L1 Band receivers. Starting in 2018, Dr. Young joined the MITRE Corporation, where he currently serves as a subject matter expert in test and evaluation of spectrum sharing technologies and applications. Outside of his current MITRE duties, he teaches classes on radio frequency measurements at the University of Colorado, Denver.
