My old colleague and good friend Tim Williams sent me the story below for inclusion in EMI Stories/Banana Skins, and I found it so interesting in so many ways that I decided to publish it as a Blog. In so very many EMC standards and other meetings on EMC, we hear that the stability of the AC mains power frequency is either ‘not an EMC issue’ or is ‘never a real EMC … [Read more...]
IQD Presents New Low Phase Noise Oscillators
One of the world’s best performing oscillators available from IQD As application requirements drive the need for greater data rates, more oscillator devices with ultra-low phase noise are required. This type of application is especially prevalent in today's connected world. Applications include fibre transceivers, gigabit Ethernet and 5G base stations. IQD is pleased to … [Read more...]
Mains Harmonic Current Emissions are Always Bad – It is Risky to Rely on the Limits or Exclusions in the Standards
Many (perhaps all) of EMC standards that are listed under the EMC Directive, that set limits for mains harmonic emissions, have exclusions (‘let-outs’) for certain types of equipment, especially: (these examples are from IEC/EN 61000-3-2 Ed.5:2018) Lighting equipment with a rated power of less than but not equal to 5W Equipment with a rated power of 75W or less, e.g. … [Read more...]
Visualize, Localize and Troubleshoot EMI Signals with Real Time Spectral Analysis

Kenneth Wyatt: Hello, and welcome to EMC Live 2016. This presentation is about visualizing, localizing and troubleshooting EMI signals with real time spectral analysis. I'm … [Read more...]
EMC Confidence Checking
I was recently working with a manufacturer of stand-alone ticket machines, who had big problems with Ethernet-related emissions. Long story short – it was the Ethernet hub they had incorporated in their machine. They had assumed that all CE-marked Ethernet hubs would be equally good for EMC, and they had several different types lying around their design department. We tested … [Read more...]
Sentinel 3 System Enhances QinetiQ’s Aircraft EMC Testing Capability
PPM Test has been working with QinetiQ Ltd to improve their EMC testing services. QinetiQ is a globally recognised leader in aircraft EMC certification testing and has been using the previous Sentinel II fibre optic link system for over 20 years. The upgrade to Sentinel 3 will be a significant enhancement to QinetiQ’s EMC testing capability. The new Sentinel 3 equipment, … [Read more...]

The Vital Role of Simulation for Virtual EMI and EMC Test Environments
Before deploying microwave and millimeter-wave devices and systems within 5G, the Internet of Things (IoT), and high-speed wireless communication, it is essential to predict their performance. This need has increased the demand for virtual test platforms through simulation software. High carrier and system bus frequencies are necessary for high-data-rate communication … [Read more...]
