Using an AM Radio as an Effective Troubleshooting Tool

An AM radio can be useful for finding both radiated emissions and ESD events. Understanding how radio works is essential for engineers to use this low-cost technology to troubleshoot complex EMI issues.

Company Reaches Settlement with FCC Over Marketing of Unauthorized Devices

In one of the largest settlements in recent memory, a New York-based company has agreed to pay a $250,000 civil penalty for selling radio equipment and devices that exceeded legal radiated emissions limits. ... Read More...

Controlling Radiated Emissions by Design: A Book Review

Much has been written on the subject of radiated emissions and it is with pleasure that I have been given the opportunity to review the Third Edition of Controlling Radiated Emissions by Design by Michel Mardiguian (with contributions by Donald. L. Sweeney and Roger Swanberg).

645 MHz Real-Time Analysis Bandwidth For Full Compliance Testing

Measurements of radiated emissions in the frequency range up to 1 GHz are performed in a semi-anechoic chamber or on open area test sites (OATS). This is typically very time consuming because according to CISPR... Read More...

Troubleshooting Radiated Emissions: Three Case Studies

Radiated emissions (RE) are often the number-one cause of compliance failures for most electronic products. This article describes simple troubleshooting steps and tools to isolate most RE issues.

Automotive EMC Case Study: HMI Graphics Influence on Radiated Emissions

A case study describing the influence of TFT LCD graphics on automotive radiated emissions testing and its impact to the FM band receiver. The underlying root-cause of the EMI issue is determined using a novel technique that decodes the display’s graphics into the transmitted RGB data and predicts the data’s impact to radiated emissions. The countermeasure implemented to resolve the issue is equally novel and does not involve any hardware optimizations. The use of test images to be used in component level EMC testing is also discussed.
