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.
