emi

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.

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.

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

In this column, the author offers a brief summary of a more systematic approach for using ferrite cores on cables. This summary can serve as a “ferrite core checklist” for design and test engineers.

Search and rescue transmitter interferes with car alarms, central locking, and garage door openers in Las Vegas.

Walkie-talkies interfere with electronic door locks on aircraft cockpits.

Navigation and control instruments can be caused to malfunction. During the approach of an Alitalia aircraft at Turin airport on 31 December, 1995, one of the 160 passengers onboard switched on his mobile phone, thus blocking the plane’s autopilot system.

Low-frequency magnetic fields, a type of electromagnetic disturbance commonly found in electric vehicles, can pose potential health hazards to humans and affect the operation of critical EV components. Here are some design techniques to help mitigate the problem.

Is it safe to use cellphones on airplanes? The real question should be: “Is it safe for passengers to use any electronic equipment on airplanes?”

Operating my personal document shredder crashes my digital TV set-top box, although it is 5 metres away. Toggling the on/off button on the set-top box restores normal operation.
