Military Frequencies Interfere with Consumer Electronics

 

Interference from radio transmissions from Navy equipment in coastal neighborhoods of San Diego is suspected of causing problems for people trying to operate wireless devices to unlock cars and open garage doors. While not taking responsibility for the trouble, local Navy officials released a statement acknowledging that some military devices operate on the same frequencies as … [Read more...]

Technology Tackles RF Interference

 

Cisco Systems Inc. recently announced that its new spectrum intelligence technology tackles challenges of RF interference, making mission-critical wireless networks more reliable. Cisco claims that its CleanAir Application-Specific Integrated Circuit is the first to solve the challenge of wireless interference by combining a patented circuit in the access point with … [Read more...]

Auto Safety Bill Includes Standard for Electronic Controls

 

Broad automobile safety legislation introduced by the Senate on Tuesday would set new standards for electronic controls, stopping distance, push-button ignition systems and data recorders. The legislation follows the recalls of more than nine million Toyota vehicles worldwide since the fall, including two major recalls for problems with sticking accelerator pedals. It also … [Read more...]

ETSI Reports to Radio Spectrum Committee

 

During the European Commission Radio Spectrum Committee’s 31st meeting in Brussels, the European Telecommunications Standards Institute (ETSI) updated the group on topics including 800 MHz band, SRD, SRR, Broadband Wireless Access, ITS, Software Defined Radio and Cognitive Radio, GNSS repeaters, and ETSI work under specific mandates. The ETSI TTCN-3 User Conference 2010 will be … [Read more...]

Reinventing Compact Immunity Testers

 

In the dim and distant days of the last century, EMC emerged relatively late on the evolutionary scale. Although engineers “of a certain persuasion” were laying the foundations as far back as the early 1960s, it was not until the European Union decided on a common identification mark (CE) to be a legal requirement in December 1994 that EMC became mainstream among test … [Read more...]

Choosing the Right Chamber for Your Test Requirements

 

Martin Wiles, Vince Rodriguez, ETS-Lindgren Developments within standards community has led to new chamber validation procedures above 1 GHz and alternative test methods using FARs. INTRODUCTION Anechoic chambers are used today for performing EMC measurements according to a variety of published EMC standards. There are many different fields of application, including … [Read more...]

Surface Scan on IC Level with High Resolution

 

Measuring of near field above ICs or open DIEs with precisely positioned microprobes is a new tool for engineers to detect and solve EMI levels. Jörg Hacker, Langer EMV-Technik GmbH, Bannewitz, Germany ABSTRACT Today, engineers have less time to develop electronic circuits. The time to market is getting shorter and the requirements on the products are increasing. It means … [Read more...]
