CEDAR PARK, Texas, June 15, 2011- ETS-Lindgren engineers will present in several technical sessions scheduled during the 2011 IEEE International Symposium on Electromagnetic Compatibility (EMC 2011) in Long Beach, California over August 14-19. The annual symposium is the premier gathering of EMC engineers from industry, academia and government organizations and attracts over 2,000 attendees from around the world.
Since antennas and probes are an important part of EMC test and measurement, ETS-Lindgren’s Senior Principal Design Engineer, Zhong Chen, returns once again as chair of the popular tutorial, “Practical Radiated Measurements using Antennas and Field Probes.” This year the tutorial will focus on advanced topics related to antenna and probe theory for applications relevant to EMC. In addition to Mr. Chen, invited speakers include Thorsten Schrader of the Physikalisch-Technische Bundesanstalt (PTB) Germany, Dennis Camell of the National Institute of Standards and Technology (NIST), and Vince Rodriguez of ETS-Lindgren. Presentations will review the usage of antennas and probes for EMC measurements, including appropriate applications of antenna factors and probe correction factors to achieve low measurement uncertainties. Other topics include calibration of field probes for complex signals, such as multi-tone, digital and pulsed waves, and calibration challenges and techniques for frequencies up to 300 GHz. Time domain methods used for antenna calibrations and test site validations will also be discussed.
Dr. Vince Rodriguez, ETS-Lindgren's Product Line Manager - Antennas, will chair the tutorial “Hot Topics in EMC Measurements: Site Validation, Time Domain and Antenna Characterization.” In addition to Dr. Rodriguez, invited speakers include Dr. Robert T. Johnk of the Institute for Telecommunication Sciences (NTIA/ITS) and Jeff Poole of Agilent Technologies. The purpose of this tutorial is to educate engineers on the recent activity in ANSI ASC C63® and IEC/CISPR developing new procedures for validating EMC radiated emission test sites above 1 GHz as well as performing antenna calibration. Topics to be addressed include measurement considerations when using a vector network analyzer for site validation above 1 GHz, time-domain anechoic chamber performance metrics, and the new requirements for knowledge of the half power beamwidth (HPBW) and radiation pattern of antennas. Dr. Rodriguez is also an invited speaker in the “Transportation System EMC” workshop; his presentation addresses issues related to metallic tables used for EMC testing.
In the popular “Demonstrations and Experiments” sessions held in the exhibit area, Joe Tannehill, EMC Software Engineer, will present “Improving EMC Test Productivity with Automated EMC Test Software.” With increasingly shorter product cycle “time to market,” the need for increasingly efficient EMC testing becomes more urgent. There are many options available today for automated EMC test software that can greatly improve EMC test productivity. This demonstration will provide practical tips on how to evaluate the software available, how to utilize your existing test instrumentation, and how to generate reports. Garth D’Abreu, Director - RF Engineering, will present “Efficient Testing Using a Reverberation Chamber” with Dennis Lewis of Boeing. The demonstration will feature an actual, working reverberation chamber to provide “real time” examples of the material presented.
The ANSI ASC C63® workshops will be held at the Hilton Hotel Costa Mesa (August 11-12) and Northwest EMC (August 13). Zhong Chen, Member of ANSI ASC C63®, is an invited speaker to address the standard C63.5 on antenna calibration. As an active member of this working group, Mr. Chen will share his expertise on antenna calibration and time domain measurement techniques. He will review the relevant background, practical applications, and changes in the antenna calibration methods as well as provide guidance on what to look for in a quality calibration.
It will certainly be a busy week for ETS-Lindgren engineers as they share their expertise in designing new solutions for the test and measurement of wireless, microwave, military and commercial products.
