Using Reverberation Chambers For High Field Strength Testing: One of the main differences between EMC testing for automotive and commercial products is the necessity to test automotive products at very high field levels. The need is very serious. With automotive EMC, human lives are at risk if essential electronic safety devices fail during operation of the vehicle. Additionally, the vehicle is not a stationary device - vehicles move and operate in a variety of electromagnetic environments from driving close to substations, to under power lines, close to airports, or to TV and radio broadcast stations, to name just a few “noisy” environments. This presentation will present an overview of immunity testing, concentrating on the ISO 11451-2 standard for full vehicle as well as the ISO 11452-2 standard for vehicle components. The issues of generating and measuring high field levels will be addressed as well as considerations presented for the reverberation chamber test environment. The reverberation chamber is an approved approach for immunity testing.

SILENT Solutions/Lee Hill

Lee Hill of SILENT will present a number of demonstrations of electromagnetic shielding applications for electronic product design. Each demonstration will be accompanied by a discussion of the underlying math and physics, as well as some commonly-held engineering assumptions. The demonstrations will include cavity resonances in simple product enclosures, imperfect cable shield terminations, pitfalls of common retrofit techniques, and the characterization of the intrinsic shielding performance of materials.

Optimizing MIL-STD 461 and CISPR Testing Using Test Receivers and FFT Detectors: The topics presented will include the improving accuracy, measurement time and documentation in performing all types of emissions testing. Real life examples and demonstration’s of how tests are properly setup and performed. Display how the use of the FFT detector can decrease long measurement and improve tests time without sacrificing overall accuracy. Detailed description and demonstration of the new CISPR-Average detector and how it will affect future commercial emissions testing. Also included a step by step description of test tools to automate and document normalized site attenuation. Measurement uncertainty and sensitivity of entire emissions test system will also be discussed. This presentation will concentrate on real life examples and displays of actual setups encountered while doing performing emissions testing.
