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...]
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...]
D.L.S. Streamlines RFID Testing for FDA EMC Compliance Requirements on Medical Devices
The FDA has established compliance criteria for electromagnetic compatibility that now includes protection against exposure to RFID devices. This recent requirement is related to potential risks due to the increase of RFID equipped devices to a level that the FDA has determined warrants inclusion on current FDA applications. AIM 7351731, an FDA recognized standard for the … [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...]
R&S®AdVISE Visual Inspection Software
A new way to eliminate human inattention R&S®AdVISE is a video-based monitoring/advisory system for use in an EMC test environment. This video detection system is designed to automate the process of visually detecting failures of a device under test (DUT) during immunity testing, eliminating human inattention and saving test time. The system is not limited to an EMC … [Read more...]

Review of MIL-STD 461 CS114– Conducted Susceptibility, Bulk Cable Injection
Introduction This article discusses CS114, including the updates contained in MIL-STD-461 revision “G”, the current revision and the associated nuances that lead to test errors. The fundamental idea behind CS114 testing is to simulate currents induced into cabling from electromagnetic (EM) fields from high level emissions, intentional or unintentional. This test allows an … [Read more...]
