CISPR 16-4-2:2011+A1:2014: Specification for Radio Disturbance and Immunity Measuring Apparatus and Methods – Part 4-2: Uncertainties, Statistics and Limit Modeling – Measurement Instrumentation Uncertainty
From the International Electrotechnical Commission webstore: "CISPR 16-4-2:2011+A1:2014 is a basic EMC publication. It specifies the method of applying Measurement Instrumentation Uncertainty (MIU) when determining compliance with CISPR disturbance limits. The material is also relevant to any EMC test when interpretation of the results and conclusions reached will be impacted … [Read more...]
Near-Field Probes for EMC Analysis of Electronics Modules, Components and IC Pins
Langer EMV-Technik GmbH has released new SX near-field probes with a frequency range up to 10 GHz enable EMC analysis of interference emitted by electronic boards, components and IC pins with high internal frequencies. High clock rates of 2 GHz, says the company, may result in fifth order harmonics of up to 10 GHz. These harmonics are coupled out by RF sources on the board … [Read more...]

Dutch Cable Companies Blame 4G for TV Interference
Cable companies in the Netherlands are claiming 4G wireless networks may be affecting their television broadcast signals. Certain frequencies used by the fourth generation mobile network technology are also employed by television broadcasters to deliver content over cable, the Netherlands Broadcasting Foundation (NOS) said this week. There have been complaints in some cities … [Read more...]
Better Magnetic Spin Wave Control for Electronic Devices
Researchers have developed a method for creating and controlling quick-moving waves in magnetic fields they say could improve communication and information processing in computer chips and other electronic devices. Created by scientists in the Department of Physics at New York University, the new technique relies on “spin waves,” waves that move in magnetic materials similar … [Read more...]

According to the company, the new HOZOX absorption technology incorporates a unique magnetic-conductive dual-layer design to … [Read more...]
To EMP or Not to EMP… Is That the Question?
So what are our thoughts on the threat of an electromagnetic pulse event (God forbid) causing some sort of catastrophic damage to our telecommunications, power, and whatever other kind of electronic infrastructure that might be out there? I know, I know…it depends who you talk to! Being in the EMC business, I’d like to believe that I understand the fundamental issue (danger) … [Read more...]
