Cable networks for television signals, sound signals and interactive services - Part 2: Electromagnetic compatibility for equipment

1.1 General Standards 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 networks and 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. 1.2 Specific scope of EN 50083 2 This 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 mains 150 kHz to 30 MHz; radiation from active equipment 5 MHz to 25 GHz; immunity of active equipment 150 kHz to 25 GHz ); screening effectiveness of passive equipment 5 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.

Kabelska omrežja za televizijske signale, zvokovne signale in interaktivne storitve - 2. del: Elektromagnetna združljivost opreme

Standardi skupine EN 50083 in EN 60728 obravnavajo kabelska omrežja, vključno z opremo in povezanimi metodami za merjenje sprejema glavne sprejemne postaje, obdelavo in distribucijo televizijskih in zvočnih signalov in z njimi povezanih podatkovnih signalov ter za obdelavo, povezovanje in oddajanje vseh vrst signalov za interaktivne storitve prek vseh primernih prenosnih medijev. To zajema • omrežja kabelske televizije (CATV) 1), • omrežja MATV in SMATV, • posamezna sprejemna omrežja in vse vrste opreme, sistemov in naprav, nameščenih v teh omrežjih. To standardizacijsko delo zajema antene in/ali posebne vhode virov signalov v glavno sprejemno postajo ali druge vmesniške točke omrežja do vhodnega terminala. Standardizacija katerih koli uporabniških terminalov (tj. uglaševalnikov, sprejemnikov, kodirnikov, večpredstavnostnih terminalov itd.) in katerih koli povezanih koaksialnih, simetričnih in optičnih kablov ter opreme je izključena.

NACIONALNI PREDGOVOR
Standard EN 50083-2:2012 je pripravil tehnični odbor Evropskega komiteja za standardizacijo v
elektrotehniki CENELEC/TC 209 Kabelske razdelilne naprave, katerega tajništvo je v pristojnosti DKE.

Slovenski standard SIST EN 50083-2:2012 je prevod evropskega standarda EN 50083-2:2012. V
primeru spora glede besedila slovenskega prevoda v tem standardu je odločilen izvirni evropski
standard v angleškem jeziku. Slovensko izdajo standarda je pripravil tehnični odbor SIST/TC AVM
Avdio, video in večpredstavitveni sistemi ter njihova oprema.
