Omfang

This standard - applies to the radiation characteristics and immunity to electromagnetic disturbances of active and passive equipment for the reception, processing and distribution of television and sound signals, as dealt with in the following parts of EN 50083 "Cabled distribution systems for television and sound signals" and with the extent from the headend respectively from the interface point to a signal source up to the system outlet or the terminal input, where no system outlet exists: - EN 50083-3: "Active coaxial wideband distribution equipment" - EN 50083-4: "Passive coaxial wideband distribution equipment" - EN 50083-5: "Headend equipment" - EN 50083-6: "Optical equipment" - covers the following frequency ranges: Disturbance voltage injected into the mains 9 kHz to 30 MHz Radiation from active equipment (5 MHz)* 30 MHz to 25 GHz Immunity of active equipment 150 kHz to 25 GHz Screening effectiveness of passive equipment (5 MHz)* 30 MHz to 1,75 GHz (25GHz)* - specifies requirements for maximum allowed radiation, minimum immunity and minimum screening effectiveness; - describes test methods for conformance testing. Coaxial cables for cabled distribution systems do not fall under the scope of this standard. Reference is made to the European Standard series EN 50117 "Coaxial cables used in cabled distribution networks". The standardization in the field of "Electromagnetic compatibility" for any user terminals (i.e. tuners, receivers, decoders, multimedia terminals etc.) is excluded from this standard. For this kind of equipment the European Standards EN 55013 and EN 55020:1994 apply. * For frequency limits given in brackets the values and/or methods of measurement in this standard are under consideration.
