radiated emissions

Ken Wyatt explores a more advanced troubleshooting tool for assessing radiated emission issues, the RF current probe. These are most useful for measuring RF common mode harmonic currents on cables.

There are many properties of antennas used to describe their performance. The antenna factor is most useful to those performing electric field radiated emissions measurements.

This is the fourth and final article in our series commemorating 70 years since the advent of modern EMC testing.

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.

When it comes to in-situ radiated emission measurements, the combination of near- and far-field measurements is often the best approach.

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.

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.

In one of the largest settlements in recent memory, a New York-based company has...

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).
