IEEE Talk - EMC Scan Technologies

RSVP Link: EMC Scan Technologies : vTools Events | vTools IEEE EMC Scan Technologies Near field scanning is a widely known and well received method for component, module and system EMC characterization. One specific emission scan technology, called the NF EMI scan, is the most common scan technology, but the immunity scan is relatively less known and less widely used. Three immunity and two emission scan technologies will be presented: ESD Scan, RF Immunity Scan, Current Spreading (CSP) and Phase Measurement Scan. ESD scan is a very effective scan technique to debug or pre-screen components or modules that are more likely to cause problems (specially soft failures) before they are integrated to a system. Its main goal is localizing weak spots or traces causing ESD gun test failures with a well-controlled disturbance source. RF Immunity Scan is very similar to ESD scan in concept, but it is a narrow-band scan while the ESD scan is a wide-band. Most currents injected by an ESD gun follow the intended path by design, but a small amount causing system upset can flow through an…
