It has been reported widely in the Japanese press that electromagnetic interference caused by illegally modified transceivers on trucks is suspected of causing two accidents by disabling the braking system of commuter buses.

The Japanese National Institute of Technology and Evaluation has announced that they have confirmed that some of the household electrical heaters available in Japan malfunction when subjected to electrical disturbances.

This article discusses the reflections on a transmission line at a shunt resistive and capacitive discontinuity along the line.

Part 2 of this article summarizes the results of recent testing conducted by the author on the shielding effectiveness of screened cables up to 2.8 GHz.

During the testing of one aircraft, we suffered a very marked and complete electrical failure of the aircraft (much to the alarm of both the test engineers and the cockpit crew) which turned out to be due to the EUT we were testing.

This article addresses two very common questions involving two interrelated and specialized sub-fields within the realm of compliance engineering.

This article addresses the impact of driver, HDMI cable, and receiver on signal quality using data eye, based on the following criteria: data eye opening, data mask violation, and data jitter.

Implementing a process of EMC compliance for a specific project is much more than simply ensuring that the design engineers follow a long list of “do’s and don’ts” in the form of EMC design rules. Following this process will reap benefits when EMC performance is evaluated at the end of the design process.

Part 1 of this two-part article explores some basic rules for terminating cable shields. Part 2 of the article will appear in our October 2022 issue and will summarize the results of recent testing conducted by the author on the shielding effectiveness of screened cables up to 2.8 GHz

Because of their mobility, vehicles will be placed in many different kinds of Electromagnetic environments.
