Electromagnetic compatibility of raspberry PI development platform in near and far-field

Abstract

Nowadays, electromagnetic compatibility constitutes a serious problem for the design and operation of electronic and electrical components, devices or systems. The reason is that this physical phenomenon can affect the correct operation of all these facilities. It can cause the errors or failures leading to fatal consequences. Raspberry Pi 2 development platform which is becoming increasingly popular includes among influenced facilities. Many of scientist equipment is based on this platform because of low cost, relatively simple development and implementation. However, Raspberry Pi represents the fascinating device regarding electromagnetic compatibility. Therefore, it contains many potential sources of electromagnetic interference. A great number of things that can be realized by Raspberry should be able to resist to the electromagnetic disturbance which is also one of work outputs. The experiments with the device under test are performed using unique rooms, namely semi-anechoic chamber and gigahertz transverse electromagnetic chamber. Test chambers offer a practically perfect solution for electromagnetic compatibility because they are insulated from exterior sources of noise. Raspberry Pi is tested in near and far-field, and the results will help in the design recommendations to eliminate the interference level regarding electromagnetic compatibility. Currently, only several research publications are dedicated to electromagnetic compatibility of the development platform. It was the reason why the authors decided to create a paper provides information about this research field. The primary purpose of the paper reported here is to analyses the level of the electromagnetic interference and susceptibility in a near and far-field. © 2018 Electromagnetics Academy.
