Standards of EN 50083 series deal with cable networks for television signals, sound signals and interactive services including equipment, systems and installations -- for headend-reception, processing and distribution of television and 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. All kinds of network like -- CATV-networks -- MATV-networks and SMATV-networks -- individual receiving networks and all kinds of equipment, systems and installations such as networks, are within this scope. The extent of these standardisation work is from the antennas, special signal source inputs to the headend or other interface points to the network up to the system outlet or the terminal input, where no system outlet exists. The standardisation of any user terminals (i.e. tuners, receivers, decoders, multimedia terminals (etc.) as well as of any coaxial and optical cables and accessories therefor is excluded. Specific scope of this part 8 This standard applies to the radiation characteristics and immunity to electromagnetic disturbance of cable networks for television signals, sound signals and interactive services and covers the frequency range 0,15 MHz to 3,0 GHz. This standard specifies EMC performance requirements and lays down the methods of measurement. Cable networks beyond the system outlets (e.g. the receiver lead, in simplest terms) which begin at the system outlet and end at the subscriber's terminal equipment shall comply with these recommondations provided that no other specific provisions apply. Requirements for the electromagnatic compatibility of receiver leads are laid down in EN 60966-2-4, EN 60966-2-5 and EN 60966-2-6.
