Candace Suriano Suriano Solutions John Suriano Nidec Automotive Motors Americas PART 1: MY CELL PHONE CAN TALK TO ME IN STEREO Dear John, I am snowed in here at home with the kids. You may be in an EMC lab solving some tough issues, but I’ve been very busy here at home with some interesting problems of my own. We’ve been bothered by the behavior of our computer … [Read more...]
A Design Review of the Automotive Radiated Emissions Test Fixture
Tom Mullineaux RF Engineer From a cold, dispassionate RF engineering perspective, the automotive radiated test set-up is a strange looking transmit/receive arrangement, with the cable harness of the equipment under test (EUT) suspended above a large copper sheet acting as the transmitter, and a huge antenna close to the chamber floor, and partly in the shadow of the copper … [Read more...]

EMC Practice – Measurement Under Interference
Clean transmission of signals from the EUT. Jorg Hacker Langer EMV-Technik GmbH It is uncommon to use an oscilloscope to monitor signals from the EUT when testing immunity to interference. The complicated environmental conditions in the anechoic chamber during RF irradiation or burst and ESD tests lead to measuring errors and unwanted interference in the EUT. Modifications to … [Read more...]
Inexpensive Radiated Immunity Pre-Compliance Testing
As an EMC consultant, it seems that lately I’ve run into many client projects where radiated immunity has cropped up as the major issue. One reason for this may be the trend in using digital and analog circuits that are powered by 3.3 volts, and lower, which decreases noise margins significantly. Sensitive analog circuitry is also greatly affected. The compliance testing for … [Read more...]
Potential Impacts of Electromagnetic Weapons on the Critical Infrastructures (View from 2012)
William A. Radasky IEEE Life Fellow WHAT IS IEMI? In recent years, Hollywood has indicated that criminals and terrorists could use electromagnetic (EM) weapons to black out a portion of Las Vegas (Ocean’s 11) or take down a counter-terrorism computer center (24). Is this fact or fiction? It turns out that Hollywood in this case is leading the public and police agencies in … [Read more...]
