SKA: an EMC Engineer's Perspective
SKA RFI and EMC Testing South Africa

Howard retains a strong interest in improving the EMC community as a whole, particularly in South Africa. Having played a large part in the EMC aspects of the Square Kilometre Array, you can read about his perspective on the science and some elements of improving the radio-quietness of the Karoo site click the image.

EMI Characterisation by Drone
 

The video above shows the work of Dr Hardie Pienaar and his legendary drone flights required to characterise the KAPB and berm shielding properties.

Technical Notes

Anritsu Noise Floor

Spectrum Analyzer operation noise floor

Plotting both the swept Spectrum Analyzer (SA) and Real Time Spectrum Analyzer (RTSA) data on the same set of axes result in the exhibition of some unusual characteristics. One of these characteristics is a discrepancy in the noise floor. To understand our investigation and see our explanation, click the image .

EMC hardening mechanisms

Modern spectrum analyzers are filled with sophisticated features, including high-speed processors performing several hundred thousand FFTs per second. However, they face one significant drawback: self-generated electromagnetic interference (EMI). In this technical note we present an EMC Cabinet to improve everyday measurements.

Video Technical Notes

Seeing EMC With Different Eyes

This video technical note aims to simplify the apparently complex field of EMC and electromagnetics in general. Many practitioners and students follow rules and standards in this field. This has several weaknesses. Pictures and illustrations are used here to aid visualization and understanding. We hope this helps!

Coupled Loop Experiment Highlighting Common EMC Problems

Loop experiment, demonstrating electromagnetic coupling. This is done through a coupled loop (twin flex) experiment, which provides an explanation of electric and magnetic field coupling. This EMC illustration is used to provoke thinking concerning your system configurations.
