Summary:
BS EN 55022 describes information technology equipment, radio disturbance characteristics and limits and methods of measurement. The procedures for measurements of signal levels are limited to the frequency range 9 kHz to 400 GHz for class A and B equipment. This standard’s goals are to establish uniform requirements for radio disturbance levels of equipment and to standardize operation conditions and interpretation of results. This document also seeks to fix limits of disturbance and describe measurement methods. This is achieved by explaining limits and methods of measurement of conducted common mode disturbances at telecommunication ports and by providing data and diagrams of mains and signal cables. This standard also gives instructions for wanted differential signals. It also provides test configurations and test sites for various information technology equipment including mains cords and table top equipment.
