EMC Bench Notes

EMC Bench Notes: Troubleshooting with a Nearby Antenna

While many designers attempt to perform radiated emissions troubleshooting at an outdoor site or in a semi-anechoic chamber using a third-party test lab facility, I've found a much more efficient method is to perform this using a nearby antenna right on your own work bench.

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.
