Ken Wyatt recommends planning in advance to install local shields for most critical wireless applications. Read on.

In this installment of Practical EMC, Ken Wyatt proves that when it comes to Apple versus counterfeit power modules, you get what you pay for. 

The PA 2522 preamplifier from Langer EMV-Technik GmbH amplifies low measurement signals over an extremely wide frequency range, from 10 MHz to 22 GHz. 

Kenneth Wyatt and Steve Sandler are inclined to recommend a solid return plane be used for all DC-DC power conversion. Read on to find out why. 

To speed up measurement time and to provide a more careful analysis of interfering signals, the Rhode & Schwarz ESW EMI test receiver will offer the possibility to increase its Fast Fourier Transform (FFT) bandwidth to 350 MHz with the R&S ESW-B350 option, and to 970 MHz with the R&S ESW-B1000 option.

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.
