The first U.S.-based clean room acceptable EMI/RFI portable shielded enclosure, has been completed and deployed in a class 1000 clean room at NASA’s Jet Propulsion Laboratory in Pasadena, Calif. It is now in service to test and run diagnostics on the Mars Science Laboratory Rover and other spacecraft. The new EMI test chamber is 9,375 cubic feet in size with an inside … [Read more...]
EU Issues EMC Regulations for Olympics
The Office of Communications for the European Union has made EMC-related regulations for the London 2012 Olympics. The regulations, titled the "Wireless Telegraphy (Control of Interference from Apparatus) London Olympic Games Regulations 2012," seek to avoid electromagnetic interference with wireless communications during the events. Any item that may cause EMI must operate … [Read more...]
Power Grids Collapse in India; Are Smart Grids a Solution?
India was affected by a second power failure around 1 p.m. Tuesday, July 31, as three regional power grids collapsed, affecting 600 million people. A Powergrid Corporation spokesman told AFP the north, northeastern and eastern grids are down, but in the process of being fixed. Power sharing was reportedly to blame for the collapse. The northern grid drew on the eastern grid … [Read more...]
Abracadabra the Broadband Signals Disappeared
Almost all EMC engineers these days are familiar with MIL-STD-461 and its various revisions because it has influenced the procedures in virtually all present day EMC standards. The original document and the A, B and C revisions all had requirements for measuring both broadband (BB) and narrowband (NB) emissions. When MIL-STD-461 was first released (July 31, 1967), the … [Read more...]

Are they out to get us?
I didn’t realize when I addressed the smart meter RF situation that it was turning into such an uproar. Now, on top of the RADHAZ comments, people are expressing concern about protection of privacy. It seems that a lot of people have a difficult time believing in RF hazards because they can’t smell, feel, touch, taste, etc. the lower RF energy levels and, therefore, a hazard … [Read more...]
Protecting the Earth’s Limited Resources
May marks the dawn of a new blog created by Interference Technology with emphasis on Electromagnetic Compatibility. I am honored to have been asked to serve as the blogger in this newest venture to reach out to members of the community. I have written many articles over the years and have always strived to make them purely technical, easily readable, and non commercial. This … [Read more...]
Rail Car Company Works On EMI Problem
Kawasaki, the manufacturer of a number of new train cars slated for use in Greenwich, Conn., is working to fix software code problems, which included an electromagnetic interference problem that caused cars to disrupt railway signal systems and garbled on-board public address announcements. Under the state’s contract with Kawasaki, the first eight pilot cars must log at least … [Read more...]
