The intergovernmental coordinating body for European state telecommunications and postal organizations has concluded that wireless devices and satellite radars cannot successfully coexist in the same part of radio spectrum, the head of the body’s technical committee announced Jan. 28. Space News reports the European Conference of Postal and Telecommunications Administrations … [Read more...]
IEC TS 62153-4-1:2014(E): Metallic Communication Cable Test Methods – Part 4-1: EMC – Introduction to Electromagnetic Screening Measurements
From the International Electrotechnical Commission webstore: "IEC TS 62153-4-1:2014(E) deals with screening measurements. Screening (or shielding) is one basic way of achieving electromagnetic compatibility (EMC). However, a confusingly large number of methods and concepts are available to test for the screening quality of cables and related components, and for defining their … [Read more...]
Electromagnetic Simulation Suite for PCB Design Delivers End-to-End SI Analysis
Simulation technology developer ANSYS has released a new electromagnetic simulation suite for the design of high-speed printed circuit boards (PCB) and integrated circuit (IC) packages. Powered by its hybrid, full-wave finite element electromagnetic solver engine, the new SIwave suite—emcompassing SIwave-DC, SIwave-PI and Slwave—delivers a complete signal integrity analysis … [Read more...]
Current Sensors Detect Electrical Faults in Tricky Environments
Researchers at the Hong Kong Polytechnic University have developed an electrical current sensor designed to power itself with harvested energy while monitoring electrical equipment. Similar to a thermometer that measures temperature, the 1-milimeter-thick smart sensors are made from rare earth multiferroics with giant magnetoelectric properties and are capable of recognizing … [Read more...]
They’re Everywhere, They’re Everywhere – Part II
In part one of this post, I noted that there are three primary EMC coupling problems that are associated with the green wire safety ground: 1. The green wire conducted noise current modulates the signal and shows up as a differential voltage change across the load.2. The green wire forms a pick-up loop and acts like a magnetic field antenna.3. The green wire loop acts as a … [Read more...]
Rugged Gigahertz Probe for RF and Power Integrity Testing
PacketMicro has expanded its HSProbeTM product family for printed-circuit board testing with a 12-GHz probe. Equipped with rugged BeCu probe tips, the new 12-GHz probe is ideal for RF and power-integrity testing that requires direct probing on top of circuit components or test pads on an uneven surface. "Constant shrinking size of circuit components makes soldering … [Read more...]
High Power Filter Modules Offer Easy System Integration
The Schaffner Group, a provider of EMC and power quality solutions, has announced its ECOsine passive harmonic filters are now available as open frame modules with extended power rating up to 400 kW/50 Hz and 500 HP/60 Hz. According to the company, the new modular filter concept specifically targets the requirements of integrators and the challenges of fitting a large amount … [Read more...]
‘Superlens’ Could Lift Restrictions on Wireless Charging
Scientists at Duke University have developed a new method of transmitting power wirelessly over much greater distances than previously achieved, bringing us closer to the possibility of a society where mobile electronic devices can be charged virtually anytime, anywhere. While the idea of wirelessly transferring power to an electronic device is not a new concept, experimental … [Read more...]
They’re Everywhere, They’re Everywhere – Part I
Read Part II here.I just finished rearranging my office. It all started with buying a new MS Windows 8 computer (that’s a story all on its own) followed closely by the failure of my printer to feed paper. So I bought a new printer, which is about two times bigger than my old one, and it wouldn’t fit in the previous location. So I moved my little flat screen TV into the old … [Read more...]
Signal and Spectrum Analyzer Features 500 MHz Bandwidth
Rohde & Schwarz has announced the availability of the new R&S FSW-B500 hardware option for all analyzers of the R&S FSW family, enabling measurements in a frequency range up to 67 GHz for applications including research and development, radar and satellite and testing of wireless connections such as WLAN or Beyond 4G (5G). According to the company, the large … [Read more...]
