EMC Bench Notes: Troubleshooting with RF Current Probes

Ken Wyatt explores a more advanced troubleshooting tool for assessing radiated emission issues, the RF current probe. These are most useful for measuring RF common mode harmonic currents on cables.

EMC Bench Notes: Interpreting Emissions Using a Near-Field Probe

Most engineers are familiar with near-field probes and that they are sensitive to E- or H-fields emanating from circuit boards, cables or enclosure seams. They are really the first order of business when evaluating a circuit board or system.

EMC Bench Notes: Embedded Processor Characterization and Design Review

Let's use the basic tools and spectrum analyzer setup described in the last two months and use them to characterize an actual embedded processor board based on the Arduino design.

EMC Bench Notes: How to Use Spectrum Analyzers for EMC

Spectrum analyzers are usually the tool of choice for troubleshooting CE or RE. In recent years, the cost of a basic analyzer has dropped markedly. However, the more expensive lab-quality analyzers will have advanced measurement features that may be worth considering.

EMC Bench Notes: Some Starting Tools

As a product designer, a major issue you'll face is radiated emissions. This month, we'll outline the basic tools to characterize and mitigate radiated emissions at your workbench. This summarizes the fundamental test equipment to identify sources of harmonic noise and characterize radiated emissions.
