Delcross Technologies announces its new Electromagnetic Interference Toolkit (EMIT) Version 4.0 software for RF and radar systems. EMIT detects possible RF cosite interference that may occur between two or more radios. “EMIT manages installed RF system performance data, simulates intra-system RF EMI effects, and helps to mitigate EMI issues, resulting in a comprehensive … [Read more...]
EMC War Stories: Letters from Home Part 2: It’s hard for my computer to sleep when I’m doing the laundry
Candace Suriano Suriano Solutions John Suriano Nidec Automotive Motors Americas Dear John, Once again it’s a cold dry winter here and I have found that there is a great way to keep warm— by doing the laundry. I discovered something really strange, though: when I’m taking the laundry out of the dryer it sometimes wakes up the computer on the desk almost ten feet away! I knew … [Read more...]
FCC Changes Certification Process
By David A. Case NCE, NCT Senior Technical Leader Regulatory Cisco Systems IncAbstract: The FCC Authorization and Evaluation Branch has been the forefront in regards to reviewing and issuing of FCC certification. With the adoption of the Telecommunications Certified Body (TCB) program, a number of these approvals were done via TCB reviewers with FCC oversight, though the FCC … [Read more...]
Harmonic Comb Generators Are Useful Tools
By Kenneth Wyatt INTRODUCTION One tool every EMC test lab should own is a harmonic comb generator. A comb generator is simply a device that will produce a set of harmonically related CW signals whose spacing is based on a fundamental oscillator frequency. For example, if we were to start with a 10 MHz clock oscillator and feed the digital output into a coax connector, we’d … [Read more...]
Tech Tidbit: Gwyneth Paltrow has ‘Golden Halo’ in Electromagnetic Image of Aura
Gwyneth Paltrow, a well-known actress, recently had her “aura read” and posted an image of it on her blog ‘Goop.’ The picture was taken by Christina Lonsdale using a rare camera invented in 1970 for the sole purpose of capturing people’s auras. Electromagnetic fields that surround our bodies, also known as auras, are normally invisible; however, they can be illuminated with … [Read more...]

The system combines an integrated power amplifier and a signal generator. It is ideal for use in electrical meters, industrial circuit breakers and shipboard equipment. The NSG 4060 offers a range of verification accessories, an extension unit … [Read more...]
New Software Yields Faster and More Flexible Measurements
Microwave Vision Group (MVG) has launched its new MVG WaveStudio, software designed to improve Over-The-Air (OTA) measurements of wireless devices. It improves measurement capabilities and shortens testing time. This software includes three parts: a free pre-processing module, licensed software, and a free post-processing viewer. The pre-processing module allows engineers to … [Read more...]
Programmer Hacks Own Wi-Fi Using Electromagnetic Waves
Jason Cole, a programmer and Ph.D. student at Imperial College in London, created an Android app that allows users to hack their own Wi-Fi using electromagnetic waves. Many believe it’s best to avoid electromagnetic radiation; however, not all believe electromagnetic waves are bad. Electromagnetic waves carry Wi-Fi signals to all electronic devices and are the foundation of … [Read more...]
