Most magazines like to review the top ten most viewed articles this time of year and Interference Technology is no different. We think our readers and authors are awesome and enjoy highlighting some of the most popular articles to date. So, here we go: What is differential and common mode current, by Ron Brewer. Unwanted conductive and radiative emissions can be … [Read more...]
Review of MIL-STD 461 CE106 Conducted Emissions, Antenna Port
Introduction Let’s take on the challenging evaluation of detection and measurement of antenna port emissions – the unintentional emissions that creep through the device circuitry and are presented to the world through an intentional wireless connection. We are NOT going into an in-depth study of antennas and we are NOT exploring what the unintentional signals may reveal. … [Read more...]
THE FINAL COUNTDOWN: EN 60601-1-2 fourth edition
We are getting closer and closer: at the end of this year the new version of the standard concerning EMC tests and measurements on medical electrical equipment will become reality… yes, the old one will be superseded. This change will influence (actually is already doing that) the whole approach to the EMC testing of these devices… on both sides! On one side, the EMC … [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...]
Overview of the DO-160 Standard
In aerospace, there is one standard that always seems to be popping up, DO-160. Aircraft suppliers are often complying with aviation authorities’ regulations by testing their product to DO-160. DO-160 is a standard that was published by the industry group Radio Technical Commission for Aeronautics known as RTCA. RTCA is not a government regulation, however the FAA, EASA and … [Read more...]
Automotive EMC
Introduction The rapid development of the automotive industry and the trend towards autonomous vehicles and ADAS systems continue to drive the need for more sophisticated EMC design and test scenarios for the automotive industry. Vehicle platforms become increasingly much more complex with electronic devices that need a reliable function without impacting security or … [Read more...]
UNECE Regulation 10: Electronic Sub-Assembly with Immunity Related Functionality
In this special guest-installment for the series of blogs on UNECE Regulation 10, Revision 5, Amendment 1 (8 October 2016), written by Elite Electronic Engineering’s Automotive Test Group Team Leader Stan Dolecki, we will look at electronic sub-assemblies with immunity related functionality. Electronic sub-assemblies (ESA) utilized in the European Union require conformity … [Read more...]
The Übersystem, Automotive Ethernet: An Interview with Stephen Jackson
With larger bandwidth, lower latency, and lighter weight, this is the Übersystem; it’s the OPEN (One-Pair Ether-Net) Alliance Ethernet for automotive, aerospace and more! On June 12th, 2018 I talked to Stephen Jackson (Steve) of Keysight’s Ixia Solutions Group about why Automotive Ethernet is the best solution for Advanced Driver Assistance Systems, ADAS, power train, body … [Read more...]
Identifying and Locating Radio Frequency Interference (RFI)
Introduction With the plethora of wireless devices, increasing broadcast, communications, and other RF sources all competing for radio spectrum, the chances of radio frequency interference (RFI) will only increase. This article explains how to identify, characterize, and locate typical interfering sources. CATEGORIES OF INTERFERENCE There are two broad … [Read more...]
