Be Careful with Low Cost/Quality Common Mode Chokes ….
Dear readers, I have been really busy working in training and EMI troubleshooting in the past months. I am happy to be here again with a new post. This month we will see a topic from a real-world situation - very interesting - for electronic designers working in conducted emissions problems. In one of the projects I was involved with several weeks ago, a product was … [Read more...]
Review of MIL-STD-461 CS103 Intermodulation, CS104 Rejection of Undesired Signals and CS105 Cross-Modulation
Introduction Rapid technology advances in the wireless communications world make test and evaluation of Radio Frequency (RF) devices a difficult subject. It seems that by the time a new device hits the market, it has been made obsolete by the next generation. I recall hearing from a major electronics manufacturer CEO that 90% of sales happen within 90-days of market release … [Read more...]
Electrostatic Discharge (ESD) in Electro-Optic Devices
Many electronic components used in highly technological devices can be damaged or degraded by sudden electrostatic discharges, known by the term Electrostatic Discharge (ESD). Components such as transistors, diodes, laser diodes, electro-optical devices, and a variety of integrated circuits are all sensitive to electrostatic discharge. Many manufacturers are increasingly … [Read more...]
Review of MIL-STD-461 CS117 Lightning Induced Transients, Cables and Power Leads
Introduction Lightning may produce a spectacular display when viewed, but the associated electromagnetic effects (EME) has the potential (pun intended) to severely damage electrical and electronic circuits. MIL-STD-461G added a new test method to evaluate device tolerance for induced current on equipment cables or insulation breakdown from the effects of indirect lightning. … [Read more...]

Review of MIL-STD-461 CS118 – Electrostatic Discharge
Introduction MIL-STD-461G, released in December 2015, added a test for Personnel Borne Electrostatic Discharge (ESD). Prior to this release, this type of test for electronic systems and sub-systems was managed at the system level under MIL-STD-464C released in 2010. Both of these standards contain similar requirements. MIL-STD-461G provides the details on testing and … [Read more...]
Digging Deep into the RF Spectrum: New CRFS Toolkit for Forensic Spectrum Analysis
Cambridge, UK: CRFS, an RF technology company, has today launched a new software tool called RFeye DeepView. DeepView is unique in two key ways. Firstly, it allows the user to analyze the RF spectrum in precise detail, to discover signals of interest that might be intermittent or hidden in the noise. It also enables the user to analyze vast data sets with unprecedented ease and … [Read more...]
