Thu, 16 Nov 2023 00:00:00 -0500

In this installment of Practical EMC, Kenneth Wyatt discusses the most common design issues for reducing self-generated EMI and outlines several mitigation techniques that have proved successful for challenging wireless products.

A Three-Step Process for Characterizing Self-Generated Interference for Wireless or IoT Products

Sat, 07 Oct 2023 00:00:22 -0400

The proliferation of electronic products has made compatibility between devices increasingly important. Products must not interfere with one another and must be designed to be immune to external energy sources. Kenneth Wyatt helps product designers or EMC engineers learn how to characterize this self-generated EMI so that these issues are addressed early when costs and design changes are minimized.

Bench Top Methods for Troubleshooting ESD

Thu, 28 Apr 2022 00:00:00 -0400

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.

Assembling an EMC Troubleshooting Kit: Radiated Immunity

Thu, 24 Mar 2022 00:00:00 -0400

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.
