(May 1, 2016) The electromagnetic spectrum is a valuable, but crowded, asset and the Army’s demand for spectrum has increased dramatically. To complicate matters, today’s operating environment is the most challenging and diverse the Army has ever known. Though primarily based in the continental United States, the Army is expected to respond rapidly to threats and to … [Read more...]
Military Tests Autonomous Ship Designed to Cross Oceans
(May 2, 2016) The military has starting testing the world's largest autonomous surface vessel — a self-driving, 132-foot ship designed to travel across oceans without a single crew member. The Sea Hunter, developed by DARPA, could potentially revolutionize the shipping industry, if tests prove successful. During the testing phase, the ship will have human operators as a safety … [Read more...]

How to Select the Right EMC Standard for Your Product
Many companies developing products find it difficult to determine the appropriate EMC standard to comply with. The IEC (International Electrotechnical Commission) has developed a web page that explains EMC and offers a tabbed selection method for determining the right standard that applies to your product family. You can then go to their web store and purchase downloadable … [Read more...]
How the IEC is Organized for EMC
International EMC standards can be confusing to the newcomer. The IEC has posted a chart as to how the various standards organizations are organized. The first level of organization is the committees, such as TC77, CISPR, and various product committees. These committees have liaisons with associated standards organizations, such as ISO, ITU, CENELEC, and many others. Many of … [Read more...]
New 1GHz Optically Isolated Differential Measurement System
Tektronix recently announced the highest bandwidth optically-isolated differential probing system at APEC 2016. The system offers complete galvanic isolation between the measured system and oscilloscope. The system will accurately measure high bandwidth differential signals in the presence of large common-mode voltages. It will also offer immunity to external interference and … [Read more...]
New Filters for Asynchronous Motor Control
TDK recently announced a new line of filters designed expressly to filter the frequency converters for asynchronous motor controllers. High frequency noise emissions from these frequency converters has become more of an issue as older motor technology is replaced with the newer variable speed - variable frequency motor controller systems. The EMI from these can cause … [Read more...]
