(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.

Pre-Compliance EMI Testing

Pre-compliance testing saves time and costs by detecting potential problems early in the design process. The use of appropriate tools and techniques improves the chances of passing the full compliance test on the first try.

Locating the Noise Source of the 10-30 MHz “Hump”

During conducted emission tests, one of the challenges manufacturers face is the resonance peaks in the harmonic noise somewhere between 10 MHz and 30 MHz. Often, no amount of filtering will eradicate or attenuate the peak.

EMC 101

As manufacturers across the world continue to develop, innovate, and expand with new technologies and products, one important facet of the design and implementation is the compliance of EMC regulations and standards for different economies and countries. Read EMC 101 to understand the background and basics of EMC, EMI, and how it relates to installations in the world.

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, these next installments argue that we started off correctly seventy years ago, but then took the wrong fork in the road in 1967.

System Components Used to Reduce Electromagnetic Interference

A few basic system components are frequently used to mitigate or suppress electromagnetic interference (EMI) in devices. As engineers and technicians involved in compliance engineering, it is important to know what these components are, what they do, how they’re most effective, and when they’re ineffective.
