BS EN 55020 is a European standard on sound and television broadcast receivers and associated equipment that discusses limits and methods of measurement to ensure the smooth functioning of equipment.
BS EN 55020 for immunity requirements applies to television broadcast receivers, sound broadcast receivers, and associated equipment intended for use in the residential, commercial, and light industrial environment.
BS EN 55020 outlines the methods of measurement and specified limits applicable to sound and television receivers and to associated equipment regarding their immunity characteristics to disturbing signals.
BS EN 55020 also applies to the immunity of outdoor units of direct to home (DTH) satellite receiving systems for individual reception.
The objective of BS EN 55020 is to define the immunity test requirements for equipment defined in the scope concerning continuous and transient, conducted and radiated disturbances including electrostatic discharges. These test requirements represent essential electromagnetic immunity requirements.
Note 1: Immunity requirements are given in the frequency range 0 Hz to 400 GHz. Radio-frequency tests outside the specified frequency bands or concerning other phenomena than given in BS EN 55020 are not required.
BS EN 55020 on immunity characteristics for sound and television broadcast receivers and associated equipment is useful for:
Sound receivers are appliances intended for the reception of sound broadcast and similar services for terrestrial, cable, and satellite transmissions. Television receivers are appliances intended for the reception of television broadcast and similar services for terrestrial, cable, and satellite transmissions. Immunity is the ability to maintain a specified performance when the equipment is subjected to disturbance (unwanted) signals of specified levels.
BS EN 55020 guideline assists you with Immunity requirements on performance criteria, antenna input connector, audio connectors, AC mains power connectors, RF voltages, and enclosure port for sound and television broadcast receivers and associated equipment.
BS EN 55020 guides on immunity measurements such as performance assessment, input immunity, RF voltage at antenna terminal, screening effectiveness, electrical transients, induced voltages, radiated fields, and electrostatic discharge for sound and television broadcast receivers and associated equipment.
This assists you to standardise the acceptable quality for sound and television broadcast receivers and associated equipment and ensuring the smooth functioning of this equipment.
