IEC 61000-4-3: 2006’s frequency escalation Jason Smith and Pat Malloy, AR RF/Microwave Instrumentation Souderton, PA An increasing number of new and proposed EMC standards are pushing the upper frequency test limits higher into the microwave spectrum. The latest EMC standard released, IEC 61000-4-3: 2006, is no exception. The upper frequency test limit has been increased from … [Read more...]
Updates on the New Release of IEC 61000-4-3 Edition 3
Continuous efforts are needed to maintain a consistently repeatable test Jason Smith, AR Worldwide Souderton, PA The IEC 61000-4-3 standard on radiated electromagnetic field immunity has long been used in order to satisfy one key criterion of the European Union’s requirements for obtaining the CE mark. It is usually used in conjunction with a specific product test standard … [Read more...]

CISPR 15, ed. 7.2 (2009-01) is entitled “Limits and methods of measurement of radio disturbance characteristics of lighting and similar equipment.” This standard applies to the emission (radiated and conducted) of radio-frequency disturbances from all lighting equipment with a primary function of generating and/or distributing light intended for illumination purposes, and … [Read more...]
AWR Acquires Simulation Software Firm
California-based AWR, well-known designer of electronic design software, has acquired a Wisconsin firm that develops RF and microwave simulation software. Simulation Technology and Applied Research (STAAR) of Mequon, WI is now a wholly-owned subsidiary of AWR. Financial terms of the deal were not disclosed. STAAR will remain in the same location, where it develops 3D … [Read more...]
Raytheon Climate Sensor Passes EM Testing
A sensor developed by Raytheon Company to increase understanding of how aerosols affect climate has demonstrated in testing that it would neither emit nor be impacted by interference from any electromagnetic impulses it might encounter in space. Raytheon’s Aerosol Polarimetry Sensor also completed vibration testing successfully. Next, the sensor will undergo a final test … [Read more...]
Proposed Federal Legislation Would Foil Felons’ Cell Phone Use
U.S. Senator Kay Bailey Hutchinson (R-TX) at left and U.S. Representative Kevin Brady (R-TX) have introduced legislation, the Safe Prisons Communications Act of 2009. The legislation would allow the Director of the Federal Bureau of Prisons, a state Governor, or a Governor’s designee (depending on whether the facility is federally or state operated) to submit a petition to the … [Read more...]
Multilayer Ceramic Capacitors Available in ESD-Resistant Version
The new E-series of multilayer capacitors from EPCOS is based on X7R material to create highly rugged and durable components. They are characterized as highly resistant to ESD pulses. With low capacitance values down to 1 nF, the E-series offers protection from EMI up to 300 MHz. With such low capacitance, these devices can also be used to implement ESD-resistant low-pass … [Read more...]
