This article describes one of the most valuable tools in the EMC engineer's “bag of tricks” – the high-frequency current probe. Current probes are invaluable for measuring high-frequency common-mode (or “antenna”) currents flowing on wires or cables. Experience has proven that poorly terminated (bonded or filtered) cables are the no. 1 cause for radiated emissions failures at a … [Read more...]

Compact Storage Chokes for High Currents
TDK-EPC, manufacturer of electronic components, modules and systems, has extended their range of ERU power inductors with the new EPCOS ERU 20 series. They are differentiated "by a particularly high current capability." At inductance values "of between 1.0 and 35.0 µH, the ERU 20 chokes possess a current capability of between 9.3 and 50.0 A. Their DC resistance values range … [Read more...]
Space Telescope Explores New Energy Extremes
NASA’s Fermi Gamma-ray Space Telescope team plans to expand the telescope’s range into the uncharted electromagnetic range, after the telescope’s more than three years in space. The Large Area Telescope (LAT) “scans the sky every three hours, continually deepening its portrait of the sky in gamma rays, the most energetic form of light.” Most visible light is between two and … [Read more...]
Fliers Refusing to Turn Off Electronics, Study Shows
Despite being warned for decades, fliers are refusing to turn off electronic devices during takeoff and landing. USA Today’s investigation included reviewing “more than 25 papers by electronics experts; presentations; papers, and advisories by government aviation officials in the USA, Canada, and the United Kingdom and Europe” and they surveyed “more than 900 frequent fliers” … [Read more...]
New Airport Body Scanner Software Increases False Alarms
France and Germany have decided to forgo the millimeter-wave scanners because of false alarms triggered by folds in clothing, buttons and even sweat. In Germany, the false positive rate was 54 percent, meaning that every other person who went through the scanner had to undergo at least a limited pat-down that found nothing. For the millimeter-wave machines, a complicating … [Read more...]
F.A.A. Approves iPad use in Cockpits
The Federal Aviation Administration approved the use of iPads instead of paper flight manuals for pilots in the cockpit on American Airlines flights. Passengers, however, are still required to shut down anything with the slightest electronic pulse from the moment a plane leaves the gate until it reaches an altitude of 10,000 feet.The 1.5-pound iPad will replace about 35 pounds … [Read more...]
Navy Tests Electromagnetic Aircraft Launch System
The Navy recently launched F-35C test aircraft CF-3 with its new electromagnetic aircraft launch system (EMALS).Testing the F-35C on EMALS provided an early opportunity to evaluate technical risks and began the process to integrate the carrier variant Joint Strike Fighter with the future carrier fleet aircraft launching system.This summer, the F-35C test team completed more … [Read more...]
iPhone Combusts on Australian Flight
A Regional Express passenger’s Apple iPhone started emitting a significant amount of dense smoke, accompanied by a red glow after landing. The Flight Attendant carried out recovery actions immediately and the red glow was extinguished successfully. The matter was reported to the Australian Transport Safety Bureau as well as the Civil Aviation Safety Authority for investigation … [Read more...]
