with this document have to be withdrawn (dop) 2012-12-21 (dow) 2013-06-21 This document supersedes EN 50083-2:2006 EN 50083-2:2012 includes the following significant technical changes with respect to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: .Frequency extensions 1.1 The upper frequency limit of conventional cable network equipment was extended from 862 MHz to 000 MHz due to market demands st 1.2 The first intermediate frequency range (1 IF range) for satellite signal transmission was extended to cover now frequencies from 950 MHz up to 500 MHz 1.3 The methods of measurement and the EMC requirements in the overlapping frequency range from 950 MHz to 000 MHz were allocated in relation to the upper frequency limit, 000 MHz, respectively the lower frequency limit, 950 MHz, of the relevant equipment under test New EMC environment in the 800 MHz band 2.1 The European Commission 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 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 broadband 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, only 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 implementation of new networks Indoor antennas The methods of measurement for all kinds of indoor antennas were combined in the new 4.9 BS EN 50083-2:2012 Licensed copy: Vocational Trading Council, Vocational Training Council, Version correct as of 31/08/2012 01:14, (c) The British Standards Institution 2012 EN

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 1) • 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 radiation from active equipment immunity of active equipment screening effectiveness of passive equipment 150 kHz to 30 MHz; MHz to 25 GHz; 2) 150 kHz to 25 GHz ; MHz to 3,5 GHz 3) (25 GHz) ; 1) 'CATV-networks' encompasses the HFC networks used nowadays to provide telecommunications services, voice, data, audio and video both broadcast and narrowcast 2) For „Inband immunity of active equipment“ and „Out-of-band immunity of active equipment, no requirements apply at present for the frequency range 3,5 GHz to 25 GHz Methods of measurement and limits are investigated for inclusion in a future amendment or revised edition 3) For "Screening effectiveness of passive equipment", no requirements apply at present for the frequency range 3,5 GHz to 25 GHz

effectiveness; • describes test methods for conformance testing No measurement needs to be performed at frequencies where no requirement is specified Due to the fact that cable networks, the former cabled distribution systems for television and sound signals are more and more used for interactive services, these networks may incorporate also equipment that carry besides the cable network equipment ports also one or more telecom signal port(s) This equipment shall be named as "multimedia network equipment" The EMC behaviour of cable network equipment, telecommunication network equipment and multimedia network equipment may be described by the following port structure (Table 1): Table - Port structure of different network equipment Port name Cable network equipment Telecommunication network equipment Multimedia network equipment Enclosure X X X Earth X X X AC/DC power supply X X X Control (e.g alarm) X X X Antenna input port X X RF network port X X Telecom signal port X X Table shows that cable network equipment and telecommunication network equipment have four common ports and, respectively, two and one individual ports Multimedia network equipment carry besides the common ports an antenna input port and/or a RF network port as well as a telecom signal port The electromagnetic compatibility requirements for "telecommunication network equipment only" are standardised in ETSI EN 300 386 (mainly) and in ETSI EN 301 489-4, those for "cable network equipment only" are given in this EN 50083-2 Equipment for multimedia networks of the above-mentioned type has to work under the same EMC conditions as equipment that is falling under the cable network and the telecommunication network EMCstandards Due to the fact, that this equipment has to work in close proximity, e.g in the same operating room, the EMC environmental conditions for all three types of equipment are the same This means that multimedia network equipment has to fulfil the EMC requirements of one of the above mentioned standards and in addition the EMC requirements, laid down in the other EMC standard, for the additional port, by which it is connected to the other network By this procedure it is ensured that multimedia network equipment fulfils the EMC conditions of one of the above mentioned networks and will neither disturb the respective other system nor will be disturbed by the respective other system via the connecting port Coaxial cables for cable networks not fall under the scope of this standard; reference is made to EN 50117 series Coaxial cable assemblies for radio and TV receivers (receiver leads) not fall under the scope of this standard; reference is made to EN 60966 series Requirements for the electromagnetic compatibility of

for equipment with an upper frequency limit ≤ 000 MHz b Applicable for equipment with a lower frequency limit ≥ 950 MHz For passive equipment an immunity level of 120 dB(µV/m) in the frequency range 790 MHz to 862 MHz can only be realised by using class A equipment NOTE For the specification of the limit values for the screening effectiveness it is assumed, that the average interfering field strength at the passive equipment will be 106 dB(µV/m) Assuming a coupling factor of about 11 dB (at 175 MHz) and an average signal level in cable networks of 70 dB(µV), a screening effectiveness of 85 dB is necessary to achieve an RF carrier-to-interference signal ratio of 60 dB (analogue modulation of the wanted signal) NOTE For the higher interfering field strength up to 120 dB(µV/m) in the 790 MHz to 862 MHz frequency range due to wireless services the calculation is as follows: 120 dB(µV/m) minus a coupling factor of about 25 dB (at 800 MHz) and a screening effectiveness of 75 dB for Class A equipment results in a signal level of the unwanted signal of 20 dB(µV) Taking into account a minimum RF signalto-interference signal ratio of 35 dB for digitally modulated signals this will lead to a wanted signal level of 55 dB(µV), which is comparable to the average wanted signal value defined for active equipment in 4.4.3.2 NOTE The potential for the existence of high external field strengths (especially in the frequency range 790 MHz to 862 MHz due to broadband wireless services) means that the use of Class B equipment may not provide the protection necessary for future proofing of the network Therefore only Class A equipment should be used in the planning and implementation of new networks NOTE The external immunity of a deployed cable network may deviate from the external immunity of the equipment as a result of building attenuation, signal levels or installation quality, etc BS EN 50083-2:2012 Licensed copy: Vocational Trading Council, Vocational Training Council,
