EMC/EMI

Troubleshooting ESD is all about tracing the path of ESD current. In this installment of Practical EMC, Kenneth Wyatt illustrates how this can be done using the HP 457A current tracer probe, or a medium-sized H-field probe, and tracing the path using an oscilloscope. 

A high percentage of EMI failures are related to structure resonances in a system. This hands-on article reviews work on structure resonances and their EMI impact, presents methods to identify and locate structure resonances, and suggests fixes using practical examples. 

The ability to perform localized radiated immunity testing is a concept rarely taught. Here Kenneth Wyatt shows he is able to solve several RF immunity issues with nothing more than a handheld personal walkie-talkie, or by producing an intense RF field using an RF generator feeding a near field probe.

In this inaugural post in his new Practical EMC blog on Signal Integrity Journal, Kenneth Wyatt lays out the major tools to troubleshoot and test for EMC compliance.

TÜV SÜD is investing £1.65million in a 1,800m² fully automated EMC and RF testing facility. Based at TÜV SÜD’s Hampshire headquarters, the latest facility’s three semi-anechoic EMC chambers will be in addition to five existing ones – significantly increasing test capacity.

Poorly designed interconnects can contribute to near field emissions, which is sometimes an indication of EMI failures, read on to see how to avoid failing an FCC test.

This first post in a new blog series, Extreme Measurements, introduces how an extreme measurement is defined. Find out how your extreme measurement story can end up on SIJ!
