INTRODUCTION Connected and autonomous vehicles have long been hailed as the answer to safe transport. Around 1.25 million people die in road traffic accidents worldwide each year according to E&T– and driver error accounts for over 90 per cent of those deaths[1]. In theory, the removal of the driver as the lead decision maker for vehicle control should reduce this number, … [Read more...]

Book Review: Foundations of Electromagnetic Compatibility (Adamczyk)
OK, this is not a book for the faint-hearted. Bogdan Adamczyk is a professor of engineering and the founder of the EMC Center at Grand Valley State University in Grand Rapids, MI. As such his recent book, Foundations of Electromagnetic Compatibility with Practical Applications (Wiley 2017, ISBN 978-1-119-12078-0) is crammed with derivations of basic electromagnetic … [Read more...]
Troubleshooting Radiated Immunity for Medical Products – Case Study
Introduction Companies making medical products have much more stringent requirements now that the new IEC 60601-1-2 (Edition 4) became effective June 17, 2017. One of the many changes included increased radiated immunity requirements in several specific wireless and communications bands (Table 1). Highlights of all the changes are included in Interference Technology’s free … [Read more...]
New Solid State Broadband E-field Sources Introduced
AR recently introduced a set of new solid state broadband E-field sources with integrated horn antennas designed to replace traveling wave tube (TWT) amplifiers for immunity testing. The new E-filed sources are controlled by a master controller. There are two frequency ranges; 18 to 26.5 GHz and 26.5 to 40 GHz. Two field levels are available; 20 V/m and 50 V/m (both measured at … [Read more...]

18 GHz Real-Time Measurement for Full Compliance Testing with High Precision
Emissions measurements of the electrical field strength in the frequency range of 1 GHz to 40 GHz are carried out in an anechoic chamber or at an open area test site. Usually these measurements are very time-consuming as the points of maximum radiation have to be found over all angular positions of the device under test (DUT) as well as over all antenna heights. DUTs with … [Read more...]
