"This European Telecommunication Standard (ETS) gives the minimum technical characteristics specifications of satellite earth stations@ capable of receiving audio-visual signals and distributed data. The equipment considered in this ETS@ is confined to the ""outdoor unit"" that consists of the antenna with the feed and the low-noise amplifier with its associated down-converter@ referred to as Low-Noise Block (LNB) converter. The output interface towards the indoor unit is defined at the LNB output connector. Consequently the coaxial cable link to the ""indoor unit""@ the Intermediate Frequency (IF) amplifier and the demodulator are not covered by this ETS. This ETS is applicable to earth stations which receive audio-visual signals and distributed data in the Fixed Satellite Service (FSS) frequency bands (10@70 GHz to 11@70 GHz and 12@50 GHz to 12@75 GHz) and in the Broadcast Satellite Service (BSS) frequency band (11@70 GHz to 12@50 GHz) from geostationary satellites. The earth station may be capable of receiving from a single or from two/more orbital locations by means of either: - motorized antenna; or - LNB which allows the reflector or feed to be re-pointed along the orbital arc; or - fixed reflector with a multiple-feed system whereby each feed is pointed towards a different position on the orbital arc. This is referred to as ""multiple-feed"" in this ETS. TeleVision Receive-Only (TVRO) earth stations are classified in two different types according to the corresponding services: Type A for collective reception@ in particular: - cable distribution head-ends: Community Antenna TeleVision (CATV); - community reception systems: Master Antenna TeleVision (MATV). Type B for individual reception@ i.e. Direct-To-Home (DTH) equipment. This ETS makes clear distinction@ wherever applicable@ between Type A and Type B equipment specification. The received television signals can be analogue or digital@ all with the associated TV sound@ and possibly other audio programmes. EMC specifications are contained in EN 50083-2 [2]@ EN 55013 [7] and EN 55020 [6]. Safety specifications are contained in EN 50083-1 [1] and in clause 5 of this ETS. This ETS deals with two types of specifications: a) specifications made: - to protect other users of the frequency spectrum (both satellite and terrestrial) from unacceptable interference; - for structural safety; - for lightning protection; - for protection from harmful interference. b) specifications: - related to the quality of reception; - to assist manufacturers to harmonize equipment design; - to enable equipment distributors and end-users to better determine equipment performance. NOTE: These specifications apply if required by the manufacturer."
