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...]
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...]
Does the Number of Bypass Capacitors for a Chip Matter?
How do you decide on the size of a bypass capacitor (or capacitors) for your project? Do you need multiple capacitors to bypass a specific chip? Are multiple value capacitors important for a given use? Do you subscribe to the old Wife’s Tail about having a couple capacitors a couple orders of magnitude different in value in parallel? Here is one take on the subject for you … [Read more...]
Emissions Test Facility – OATS vs SAC?
You’ve been tasked by management to build a new, from scratch, EMC test facility. Among other items, you need to decide between an Open Area Test Site (OATS) or an RF Semi-Anechoic Chamber (SAC). How do you decide? To someone who has been there, done that, the choice is clear, but what are some factors that might sway the decision one way or the other? Design of an … [Read more...]
Classical Shielding Theory vs. Near-Field Measurements
This article addresses the fundamental concepts underlying the classical shielding theory based on Schelkunoff’s equations [1]. In order to assess the applicability of these equations, an understanding of their origin, assumptions made in their derivations, and their limitations, are needed. This tutorial article addresses each of these points. The goal is not to show the … [Read more...]
What You See With Near Field Probes
In EMI/EMC troubleshooting, near field probes (NFPs) are great tools. Let's review how to understand what you really see at the screen of your instrument with a magnetic near field probe. EMI/EMC problems (radiated and conducted emissions) are usually related with current in your circuits: high frequency currents (i.e. high di/dt currents) are responsible of radiation from … [Read more...]
