Determining Semi-Anechoic Chamber Resonance as a Source of Radiated Emission Measurement Variation Between Chambers and Comparing to OATS Measurements
INTRODUCTION This article describes the lack of an acceptable correlation between anechoic chamber and open field test site radiated emission measurements, which were described in reference 1 in 2000, as well as a lack of correlation between chambers. It was found that emission measurements, which were over the limits in one facility, would pass in another. The lack of a … [Read more...]

EMC Radiated Emission Measurements at 1/3/5/10/30 Meters
INTRODUCTION There are two principal types of emission measurements in the world of electromagnetic compatibility, conducted emission and radiated emission. The conducted emission measurements are either a voltage-capacitive tap type of measurement (typically on a power line) or they are a current-clamp type of measurement (typically on a signal line). Radiated emission … [Read more...]
Resilience is Key to the Connected and Autonomous Revolution
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...]
