(Re)Discovering the Lost Science of Near-Field Measurements, Part 3

This article is the third in a series commemorating 70 years since the advent of modern EMI testing. But this last article is itself divided into multiple parts, due to the topic’s complexity. Unlike the previous two articles, which mainly tracked evolution and explained issues, this series of installments argues that we started off correctly seventy years ago, but then took the wrong fork in the road in 1967.

In-Situ Radiated Emission Testing of Large Systems Installations

When it comes to in-situ radiated emission measurements, the combination of near- and far-field measurements is often the best approach. Near-field measurements can help identify the sources of emissions, including individual modules or components and their frequency and amplitude characteristics. This information can then be used for far-field measurements. Far-field measurements involve using antennas to measure the radiated noise, with full‑size antennas recommended for measurements between 30 and 200 MHz.

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).
