Automotive EMC Testing: CISPR 25, ISO 11452-2 and Equivalent Standards, Part 2

This two-part article provides an overview of current automotive EMC standards and the intricacies of chamber testing automotive systems and components. In Part 2 of this article, we’ll address antennas used for automotive EMC testing.

Conducted Emissions Feedback from VSD-Operated Products

The ubiquitous increase in the use of mains power switching devices has been paralleled by the increase in nuisance tripping of GFCIs and other protection devices. Nuisance tripping can be identified to contain such high frequency signals and these must be properly taken into account when designing proper GFCI operation in this environment.

Application of Thrifty Test Equipment for EMC Testing

EMC testing laboratories often have limitations (limited availability, lead times, etc.) that can make it difficult to obtain timely results from routine troubleshooting. Inexpensive test equipment can support efficient and economical in-house EMC troubleshooting.

Firmware: The Inexpensive Way to Address EMC Issues

Firmware is integral to the operation of most devices, and may represent an easier and less expensive pathway for addressing EMC issues. This article presents different approaches to modifying firmware as well as case studies illustrating the potential effectiveness of this approach.

Let’s Talk About… The Value of Pre-compliance Testing

Without much effort and expense, it is possible to perform pre-compliance testing in a manner that saves considerable time and money without commercial or financial risks associated with purchasing a full-compliance test facility.

Radio and EMC Testing Considerations

Understanding radio compliance and electromagnetic compatibility (EMC) issues to help ensure that products meet regulatory testing requirements and customer expectations.

Defining Product Grounding in the Automotive EMC Test Plan

This article presents the importance of defining product case and load simulator grounding in an automotive EMC test plan.

EMC Testing… The EU Experience

Changes to the FCC compliance rules in the U.S. now enable manufacturers to save time and cost by allowing self-testing. This article outlines some of the basic factors that determine RF and EMC behavior and how these determine compliance test methods.

Selecting the Proper RF Amplifier for the Required Field Strength

More power costs more money when it comes to broadband power amplifiers, so we typically only specify/buy to meet our current needs rather than what we may need in the future.

Importance of Traceability in EMI Measurements

This article will introduce the concept of traceability, discuss the role an EMC test laboratory must assume to ensure traceability of test results and will introduce a future amendment to CISPR 16-1-1 which describes the requirements for calibration of EMI receivers and spectrum analyzers.
