EN 50083-2:2012 includes the following significant technical ch
30、anges with respect to EN 50083-2:2006: 1. .Frequency extensions 1.1. The upper frequency limit of conventional 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 extende
31、d to cover now frequencies from 950 MHz up to 3 500 MHz. 1.3. The methods of measurement and the EMC 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 r
32、elevant equipment under test. 2. 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 G
33、roup “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-ban
34、d 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 ran
35、ge. 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 b
36、ut a note was added recommending that only Class A equipment should be used in the planning and implementation of new networks. 3. Indoor antennas The methods of measurement for all kinds of indoor antennas were combined in the new 4.9. BS EN 50083-2:2012+A1:2015EN 50083-2:2012+A1:2015 5 BS EN 50083

Foreword to amendment A1BS EN 50083-2:2012 7 EN 50083-2:2012 1 Scope 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 dis
43、tribution 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), MATV-networks and SMATV-networks, individual receiv
44、ing 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
45、 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
46、 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
47、 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
48、equipment 150 kHz to 25 GHz 2); screening effectiveness of passive equipment 5 MHz to 3,5 GHz (25 GHz) 3); 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 eq
49、uipment“ 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 requir
