EN 50083-2:2012

1.1GeneralStandards of the EN 50083 and EN 60728 series deal with cable networks including equipment and associated methods of measurement for headend reception, processing and distribution of television signals, sound signals and their associated data signals and for processing, interfacing and transmitting all kinds of signals for interactive services using all applicable transmission media.This includes•CATV-networks ),•MATV-networks and SMATV-networks,•individual receiving networksand all kinds of equipment, systems and installations installed in such networks.The extent of this standardisation work is from the antennas and/or special signal source inputs to the headend or other interface points to the network up to the terminal input.The standardisation of any user terminals (i.e., tuners, receivers, decoders, multimedia terminals, etc.) as well as of any coaxial, balanced and optical cables and accessories thereof is excluded.1.2Specific scope of EN 50083 2This European Standard•applies to the radiation characteristics and immunity to electromagnetic disturbance of EM active equipment (active and passive equipment) for the reception, processing and distribution of television, sound and interactive multimedia signals as dealt with in the following parts of EN 50083 or EN 60728 series:–EN 60728-3"Active wideband equipment for cable networks";–EN 60728-4"Passive wideband equipment for coaxial cable networks";–EN 60728-5"Headend equipment";–EN 60728-6"Optical equipment";•covers the following frequency ranges:disturbance voltage injected into the mains150 kHz to 30 MHz;radiation from active equipment 5 MHz to 25 GHz;immunity of active equipment150 kHz to 25 GHz );screening effectiveness of passive equipment5 MHz to 3,5 GHz (25 GHz) );•specifies requirements for maximum allowed radiation, minimum immunity and minimum screening effectiveness;•describes test methods for conformance testing.
