Introduction A very useful tool for troubleshooting EMC issues is the near field probe. Due to its small size (compared against antennas) the most common use of these tools is to aid in detection of the source of a particular signal (emission), or as a local field-generating source (immunity), helping you to find weak spots in your device under test. There are several options … [Read more...]
DO-160 Critical Sections – Cable Bundle for Indirect Lightning
In the last article of critical DO-160 sections we talked about pin injection testing for indirect lightning. Like pin injection, cable bundle is under Section 22.0 of DO-160. However, cable bundle is a completely different beast and warrants its own discussion. For future articles we will also be discussing the following sections of DO-160 so stay tuned for more great … [Read more...]
Design for DO-160 Pin Injection for Indirect Lightning
In my first article, I gave an overview of RTCA’s DO-160 and the electrical EMC sections that it entails. In the next few articles I will be discussing the most critical EMC section of DO-160. Critical sections DO-160 Sect 16.0 - Power Input Sect 20.0 - Radio Frequency Susceptibility (Radiated and Conducted) Sect 21.0 - Emission of Radio Frequency … [Read more...]
Interview: Dr. Ralf Heinrich discusses the new IEC 61000-4-31 immunity standard
Does your product use AC mains <16A? IEC 61000-4-31 relates to the conducted immunity of electrical and electronic equipment to electromagnetic disturbances coming from intended and/or unintended broadband signal sources in the frequency range 150 kHz up to 80 MHz. In this blog post, Kenneth Wyatt, Senior Technical Editor at Interference Technology, spends some … [Read more...]
RFID Takes AIM
Radio-Frequency Identification (RFID) technology has been in use for the last 50 years. The technology is used as an identifier of a device for inventory or status tracking. It serves similar functionality as bar-coding, with continuously increasing advantages. The reduction in costs to produce the components of RFID has caused the technology to proliferate in recent … [Read more...]

About 50% of the submitted papers were rejected in the review process. Close to 600 international … [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...]
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...]
