Tiivistelmä
Introduction: Electromagnetic Compatibility (EMC) means the ability of a device to function properly in its intended environment without introducing intolerable electromagnetic interference in that environment [1]. EMC education is a part of electrical and electronic engineering curriculum in many Universities. Full-Compliance EMC measurements require special measurement environment and equipment that are not available in many Universities for teaching purposes.
This paper presents alternative measurement methods for demonstrating different EMC phenomena. These methods are simple and easy to realise with basic electronics measurement equipment in a normal teaching laboratory. The presented measurements are divided according to the EMC test standards. Each presented measurement and test method has been tested. Simple digital electronics boards and Raspberry PI computer have been used as example devices. This paper is based on a Licentiate thesis made by the main author during 2015-2016 [2].
It is important to underline that these measurement methods are not comparable to standard tests but these can be used to learn and better understand different EMC phenomena and design rules to make a device EMC compliant. These measurements can also help students to better understand general electromagnetics from engineering perspective. In addition to teaching purposes, these measurement methods are suitable to be used for the EMC troubleshooting and EMC Pre-Compliance testing in prototype phase or to check the effectiveness of design changes after failed standard measurement and before a retest.
