Conducted emission tests can provide reasonably accurate results and also serve as a reliable indicator of radiated emissions, as some of these emissions propagate through cable wiring.

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

The paper machine process requires precise control of the paper sheet tension as it progresses through the machine.

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 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.

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.

One car manufacturer found that the craze for CB radio caused more than a jamming of the airwaves.

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.
