The EMC Blog

- January 31, 2014

Kenneth Wyatt is an independent consultant and specialist in electromagnetic compatibility (EMC) design, test and troubleshooting. In The EMC Blog, he discusses issues, trends, EMC design, and product troubleshooting techniques. One specialty is his use of do-it-yourself probes and use of low-cost test equipment and measurement techniques for evaluating EMC issues on the workbench. He's also the author of The EMC Pocket Guide and EMI Troubleshooting Cookbook for Product Designers, both published by SciTech Publishing.

Review: TPI Version 4 4400 MHz RF synthesizer

  • 07.20.2014

Earlier, I wrote a short review on a low cost RF synthesizer from Trinity Power, Inc. (TPI) Version 5, a very small, but relatively powerful RF source that could be used for localized radiated immunity pre-compliance testing of products. The company also sells Version 4, a larger RF synthesizer that sacrifices maximum RF output level for a flatter RF output response. I had a chance to try it out recently.Read More...

Review: Signal Hound BB60C real time 6 GHz spectrum analyzer

  • 07.08.2014

The Signal Hound series of spectrum analyzers are about as small as three large-size Hershey chocolate bars stacked on top of each other. The unit offered for review is the recently released model BB60C real time analyzer, which can tune from 9 kHz to 6 GHz with a dynamic range of +10 to approximately -158 dBm (DANL, which is dependent on resolution BW). It can easily fit within a standard briefcase with room left over for a medium sized laptop.Read More...

There are a few classic texts on EMC theory and design, and after reading Keith Armstrong’s, EMC Design Techniques for Electronic Engineers, I feel it is also destined to become a member of the classics club. Read More...

Troubleshooting EMI on your bench top

  • 05.19.2014

If your product is failing radiated emissions at the test lab, it’s often more cost-effective to perform any detailed troubleshooting at your own facility where you can take time to methodically isolate the source and try out several potential fixes. Read More...

Gaps in return planes - yes or no?

  • 04.19.2014

As a participant during the panel discussion on EMC versus SI at the recent DesignCon 2014, I sensed (along with some in the audience) that there was disagreement as to whether it was OK to cross a gap in the return plane with a high speed, fast-edged, signal. Unfortunately, there was too little time in which to come to an agreement or to illustrate the conditions in which it was OK, or not OK.Read More...
