Integrating a radio into a medical device can have many benefits but also introduces new challenges in compliance. Ensuring coexistence with other radios can be critical to the essential performance of medical equipment.

While articles and papers have been written in the past concerning the protection of high voltage power grids throughout the world, there has not been sufficient emphasis on the near-term plans to harden existing facilities. This article provides a specific cost-effective approach to protect existing power system assets over time from the threats of HEMP and IEMI.

While many designers attempt to perform radiated emissions troubleshooting at an outdoor site or in a semi-anechoic chamber using a third-party test lab facility, I've found a much more efficient method is to perform this using a nearby antenna right on your own work bench.

Ken Wyatt provides an overview of radiated emissions pre-compliance testing. He covers equipment setup, field strength calculations, and strategies for managing ambient interference. The guide aims to enhance EMC troubleshooting skills and reduce formal testing expenses.

Spectrum analyzers are usually the tool of choice for troubleshooting CE or RE. In recent years, the cost of a basic analyzer has dropped markedly. However, the more expensive lab-quality analyzers will have advanced measurement features that may be worth considering.
