33、 the ETSI standards approval procedure in Public Enquiry 19 and Vote 25. Every ETS prepared by ETSI is a voluntary standard. This ETS may contain text concerning type approval of the equipment to which it relates. This text should be considered only as guidance and does not make this ETS mandatory.
34、_ 3404583 O053604 T = Page 11 ETS 300 158:1992 1 Scope The scope of this European Telecommunication Standard (ETSI is to give minimum specifications for the standardisation of the technical characteristics of satellite receiving earth stations, capable of receiving audiovisual signals and associated
35、 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 converter (LNB). The output interface towards the indoor unit is defined at the LNB
36、 output connector. Consequently the coaxial cable link to the “indoor unit“, the intermediate frequency amplifier and the demodulator are not covered in this ETS. Standards for the “indoor unit“ are the responsibility of CENELEC. This ETS is applicable to earth stations which receive audiovisual pro
37、grammes in the Fixed Satellite Services (FSS) frequency ranges, from 10,70 GHz to 1 1,70 GHr and from 12,50 GHz to 12,75 GHz (Ku band). The Television Receive Only (TVROs) are classified into two different types according to the corresponding services: Type A for collective reception, in particular:
38、 - cable distribution head ends (Community Antenna Television: CATV); - community reception systems (Master Antenna Television: MATV). Type B for individual reception, .e. Direct-To-Home (DTH) equipment. A clear distinction is made, wherever applicable between specifications for Type A and for Type
39、B in the various Clauses of this ETS. The received television signals can be PAL, SECAM, NTSC or the different MAC systems, all with the associated TV sound, and possibly other audio programmes. Any other new TV systems (eng. digital) may be received in the future, provided those systems operate wit
40、h the FSS ku band. Data may be present as coded signals inside television signals. This ETS specifies: a) Requirements (indicated in Clause 5) The requirements cover mechanical, electrical safety and the interface with the indoor unit as well as some electromagnetic compatibility aspects. The test a
41、nd measurement procedures associated with the normative requirements detailed in Clause 5 of this ETS, shall be met in order to qualify compliance with this ETS. b) Recommendations (indicated in Clause 6) The recommendations are related to the quality of reception and are intended to assist manufact
42、urers harmonise equipment design and to enable equipment distributors and end-users to better determine equipment performance. Previous page is blank Page 12 _. ETS 300 158:1992 = 3404583 O053605 925 The test and measurement procedures associated with the informative recommendations detailed in Clau
43、se 6 of this ETS, are given for verification purposes only. The compliance with the recommendations will not be taken as a condition to comply with the standard for TVRO equipment. All the tests related to the requirements shall be performed and the results entered in the data sheet of the test repo
44、rt. The ability to comply with recommendations shall also be noted in the data sheet of the test report. 2 Normative references This ETS incorporates by dated or undated references, provisions from other publications. These normative references are cited at the appropriate places in the text and the
