14、(ETSI). This European Telecommunication Standard (EIS) has been prepared by the Radio Equipment and Systems (RES) Technical Committee of the European Telecommunications Standards Institute (ETSI) and the European Broadcasting Union (EBU)/ETSI Joint Technical Committee (JTC) in response to European C
15、ommission mandate BC-T-353. This ETS, together with ETS 300 384, is intended to become a harmonized standard, the reference of which is intended to be published in the Official Journal of the European Communities referencing Council Directive 89/336/EEC (EMC Directive). The technical characteristics
16、 which are relevant to the EMC Directive are listed in annex A. Although all technical specifications that apply to the radiocommunications product on a “mandatory“ basis to have it placed on the market and brought into use are included in this ETS and ETS 300 384, not all technical specifications h
17、ave a similar status: - compliance with the technical specifications, as referenced to the EMC Directive, allow the affixation of the CE mark and the free circulation of the radiocommunications product; - the technical specifications referenced in the ERC Decision are for type approval purposes as p
18、ari of the licensing provisions for bringing the equipment into use. This latter subset of the technical specifications, although contained in the ETSs, is not harmonized under the terms of the EMC Directive, with the exception of those specifically referenced to the EMC Directive. Other standards c
19、over radio communications equipment not listed in the scope. Transposition dates Date of adoption: Date of latest announcement of this ETS (doa): 21 February 1997 30 June 1997 Date of latest publication of new National Standard or endorsement of this ETS (dop/e): 31 December 1997 Date of withdrawal

21、he assessment of VHF FM sound broadcasting transmitters and ancillary equipment in respect of ElectroMagnetic Compatibility (EMC). Technical specifications related to the antenna port are not included in this ETS. Such technical specifications are found in the related product standards for the effec
22、tive use of the radio spectrum. This ETS specifies the applicable EMC tests, test methods, the limits and the minimum performance criteria for VHF FM sound broadcasting transmitters operating in the frequency range 87,5 MHz to 108 MHz, and any associated ancillary equipment. The EMC requirements hav
23、e been selected to ensure an adequate level of compatibility for apparatus at broadcast transmitter site environments. The levels however do not cover extreme cases that may occur in any location but with a low probability of occurrence. This ETS may not cover those cases where a potential source of
24、 interference that is producing individually repeated transient phenomena or a continuous phenomenon is permanently present, e.g. a radar or broadcast transmitter on the same site or in the near vicinity. In such a case it may be necessary to use special protection applied to either the source of in
25、terference, or the interfered part, or both. Compliance of radio equipment to the requirements of this ETS does not signify compliance with the requirement related to the use of the equipment (licensing requirements). Compliance to this ETS does not signify compliance to any safety requirement. Howe
26、ver, it is the responsibility of the assessor of the equipment that any observation regarding the equipment becoming dangerous or unsafe as a result of the application of the tests of this ETS, should be recorded in the test repod. 2 Normative references This standard incorporates, by dated or undat
27、ed reference, provisions from other publications. These normative references are cited at the appropriate places in the text and relate to the publications listed hereafter.

36、ancillary equipment: Equipment (apparatus), used with a VHF FM sound broadcasting Transmitter , is considered as an ancillary equipment (apparatus) if: - the equipment is intended for use in conjunction with a VHF FM sound broadcasting Transmitter to provide additional operational and/or control fea
37、tures to the radio equipment (e.9. to extend control to another position or location); and - the equipment cannot be used on a stand alone basis to provide user functions independently of a VHF FM sound broadcasting Transmitter; and - the VHF FM sound broadcasting Transmitter to which it is connecte
38、d, is capable of providing some intended operation such as transmitting without the ancillary equipment (.e. it is not a sub-unit of the main equipment essential to the main equipment basic functions). dBqps: absolute weighted voltage level measured according to ITU-R Recommendation 468-4 4 in sound
39、-programme transmission. manufacturer: The legal entity responsible for placing the product on the market. port: A particular interface of the specified equipment (apparatus) with the external electromagnetic environment. switching range: The maximum frequency over which the VHF FM sound broadcastin
40、g Transmitter can be operated without change of components or re-alignment. VHF FM Sound Broadcasting Transmitter (VHF/FM Tx): An active device that, when connected to an antenna, radiates a Frequency Modulated (FM) signal in the frequency band 87,5 MHz to 108 MHz. A VHF/FM Tx is intended to be used
41、 at a fixed location and therefore is defined as a fixed equipment. A VHF/FM Tx includes the following categories of equipment: - a) transmitter: a VHF/FM Tx which consists a base-band fed FM modulator, (exciter), optionally followed by stages of Radio Frequency (RF) amplification. The baseband inpu
42、t may take the form of audio, multiplex, or a digitally-coded signal; Page 9 ETS 300 447: March 1997 a VHF/FM Tx which receives an input signal off-air, and re-broadcasts the same signal on a different frequency; a VHF/FM Tx which receives an input signal off-air, and re-broadcasts the same signal o
43、n the same frequency; a VHF/FM Tx which comprises an amplifier declared by the manufacturer to be capable of being connected to a radiating antenna system.

45、smitter Very High Frequency General test conditions Test conditions The eaubment shall be tested under normal te t conditi ns c ntained in the relevant product and basic standa;ds or in the information accompanying the equipment, which are within the manufacturers declared range of humidity, tempera
46、ture and supply voltage. The test conditions shall be in accordance with IEC 244-1 3 unless otherwise stated, and shall be recorded in the test report. The test configuration shall be as close to normal intended use as possible and shall be recorded in the test report. For immunity tests, the output
47、 of the VHF/FM Tx shall be monitored as specified in this ETS, subclauses 4.2, 4.3,4.4, 4.5 and 4.6 shall apply and the conditions shall be as follows: - the VHF/FM Tx shall be operated at its declared normal maximum output power modulated with a suitable test signal (see subclause 4.2); - for trans
48、posers, RF power amplifiers and active deflectors the wanted RF input signal shall be coupled to the RF input port. 4.2 Arrangements for test signals at the input of the VHWFM Tx Any unused baseband input ports shall be terminated according to the manufacturers instructions. For the purpose of these
49、 tests, no audio modulation is applied to the VHF/FM Tx (quiet channel). If a VHF/FM Tx incorporates baseband processing and/or coding equipment (e.g. stereo encoder, limiter, Radio Data System (ROS) encoder), this equipment shall be active as in normal operation. In the case of transposers and active deflectors, the wanted RF input signal shall be set to a level of -27 dBm, and at a frequency determined from the manufacturers specifications. In the case of RF power amplifiers, the input shall be delivered from an external exciter provided by the man
