University’s Light Rail Yields Potential Electromagnetic Interference to Expensive Lab Equipment

 

A University of Minnesota light rail reportedly causes electromagnetic radiation and vibrations, which could disturb university research in chemistry and medical departments, the Minnesota Daily reported. For more than a year, Metro Transit and the Metropolitan Council have attempted to reduce the electromagnetic disturbances from the Green Line Light Rail. The University of … [Read more...]

Real-time Spectrum Analyzer Measures Frequencies up to 27 GHz

 

Berkeley Nucleonics Corporation introduces its new Model RTSA7500 – a real-time spectrum analyzer that can measure up to 27 GHz. The spectrum analyzer is cost-effective and powerful; it costs less than $14,000 and can measure frequency ranges from 100 kHz to 8 GHz, 18 GHz, or 27 GHz. “The Model RTSA7500 has all the standard features of a spectrum analyzer such as frequency … [Read more...]

Dual Band Amplifier Produces Continuous Power from 400 W to 800 W

 

MILMEGA, part of AMETEK Compliance Test Solutions group, debuted its new dual band amplifier, the AS0104-800/400, to run automotive radar pulse tests. It reduces testing time and is also easy to set up and operate, according to the company. The amplifier produces continuous wave power  from 400 W to 800 W in frequency ranges from 1 GHz to 4 GHz. “AS0104-800/400 has been … [Read more...]

Automatic SAR Measurement Robot Debuts at IMS 2015

 

This week at the IEEE International Microwave Symposium (IMS), ART-Fi will showcase the “SARborg,” an automatic SAR measurement robot. The SARborg saves time, improves accuracy and repeatability, and is precise with its measurements. “We call it the SARborg, because it’s a robot that runs through batteries of SAR tests completely hands-free. We have essentially roboticized the … [Read more...]

Scientists Concerned with Electronic Device Radiation File Appeal to UN

 

Scientists from 39 different nations are concerned about electromagnetic fields (EMFs) and radiation from mobile phones, tablets, laptops and other electronic devices. A group of 199 scientists have filed an appeal, titled “International EMF Scientist Appeal,” with the United Nations and World Health Organization (WHO) and have requested the organizations adopt more protective … [Read more...]

FCC’s Plan to Revitalize AM Radio Concerns Listeners

 

On May 15, iHeartMedia met with the FCC Media Bureau to discuss the current plan to revitalize AM Radio and to discuss an ex parte letter describing possible changes to AM radio stations. The plan in place will reduce skywave interference protection which make it easier for AM radio stations to operate and give users more flexibility. Jeff Littlejohn of EVP/Engineering and … [Read more...]

Navy Conducts First On-board Testing of Electromagnetic Catapult

 

The U.S. Navy fired the first on-board catapult shots using the Electromagnetic Aircraft Launch System (EMALS) on the Gerald R. Ford CVN 78. The EMALS uses bursts of electromagnetic energy to launch planes into the air more efficiently. The EMALS offers increased reliability and efficiency, higher-launch energy capacity, more accurate speed control, and a smoother acceleration … [Read more...]

Anti-jamming Technology Effective in Protecting Satellites from Interference

 

Boeing Engineers have tested an anti-jamming technology for satellites that shields signals from interference and have proven the technology is capable of operating both on the ground and in a satellite-based networking hubs. The test was completed under a contract for the U.S. Air Force Space and Missile Systems Center and was supervised by the U.S. Government. It was … [Read more...]
