31、CLC/TC 209 “Cable networks for television signals, sound signals and interactive services“. The following dates are fixed: latest date by which this document has to be implemented at national level by publication of an identical national standard or by endorsement (dop) 2012-12-21 latest date by whi

32、ch the national standards conflicting with this document have to be withdrawn (dow) 2013-06-21 This document supersedes EN 50083-2:2006. EN 50083-2:2012 includes the following significant technical changes with respect to EN 50083-2:2006: 1. .Frequency extensions 1.1. The upper frequency limit of co

33、nventional cable network equipment was extended from 862 MHz to 1 000 MHz due to market demands. 1.2. The first intermediate frequency range (1stIF range) for satellite signal transmission was extended to cover now frequencies from 950 MHz up to 3 500 MHz. 1.3. The methods of measurement and the EMC

34、 requirements in the overlapping frequency range from 950 MHz to 1 000 MHz were allocated in relation to the upper frequency limit, 1 000 MHz, respectively the lower frequency limit, 950 MHz, of the relevant equipment under test. 2. New EMC environment in the 800 MHz band 2.1. The European Commissio

35、n has requested CENELEC and ETSI to draft immunity requirements for equipment, to protect against disturbance from the new wireless service in the 790-862 MHz band. 2.2. A CENELEC/ETSI Joint Working Group “Digital Dividend” was formed to describe the new EMC environment and to advise on appropriate

36、test methods and limits. 2.3. EN 50083-2 is the standard specifying immunity requirements for active and passive cable network equipment. 2.4. The method of measurement and the requirements for in-band immunity were extended taking into account this new EMC environment due to the allocation of broad

37、band wireless services in the frequency band 790 MHz to 862 MHz. As a consequence, the limits of in-band immunity were specified for analogue and additionally for digital signals in this frequency range. 2.5. Consequently it is recommended, that, where cable networks and wireless networks coexist, o

38、nly the transmission of digitally modulated signals should be used in the frequency range 790 MHz to 862 MHz. 2.6. For passive equipment, Class A and Class B specifications were kept in the standard but a note was added recommending that only Class A equipment should be used in the planning and impl

39、ementation of new networks. 3. Indoor antennas The methods of measurement for all kinds of indoor antennas were combined in the new 4.9.

44、easurement 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 1),

45、 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

46、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 radia
