Foreword This Candidate Harmonized European Standard (Telecommunications series) has been produced by ETSI Technical Committee Electromagnetic compatibility and Radio spectrum Matters (ERM).

19、 The present document has been produced by ETSI in response to a mandate from the European Commission issued under Council Directive 98/34/EC 8 (as amended) laying down a procedure for the provision of information in the field of technical standards and regulations. The present document is intended

20、to become a Harmonized Standard, the reference of which will be published in the Official Journal of the European Communities referencing the Council Directive on the approximation of the laws of the Member States relating to electromagnetic compatibility (“the EMC Directive“) (89/336/EEC 2 as amend

21、ed) and Directive 1999/5/EC 3 of the European Parliament and of the Council of 9 March 1999 on radio equipment and telecommunications terminal equipment and the mutual recognition of their conformity (“the R ElectroMagnetic Compatibility (EMC) standard for radio equipment and services; Part 1: Commo

Further provisions related to test conditions for broadcasting service transmitters are specif

32、ied in the present document. 4.1 General For emission and immunity tests the test modulation, test arrangements, etc., as specified in the present document, clauses 4.1 to 4.5, shall apply. For immunity tests, the output of the Tx shall be monitored as specified in the present document, clause 4.2.3

33、. 4.2 Arrangements for test signals The provisions of EN 301 489-1 1, clause 4.2 shall apply. 4.2.1 Arrangements for test signals at the input of transmitters The provisions of EN 301 489-1 1, clause 4.2.1 shall apply, with the following modifications. If the transmitter under test incorporates base

34、-band processing and/or coding equipment (e.g. a RDS encoder for a FM transmitter), then this equipment shall be active as in normal operation. The manufacturer shall provide reference encoders and the tests shall be carried out with these in operational mode. ETSI ETSI EN 301 489-11 V1.3.1 (2006-05

35、) 9 If the transmitter under test does not include integrated base-band processing and/or coding equipment, the manufacturer shall declare whether the transmitter is designed for operation with or without encoder(s). The manufacturer shall clearly state this in the product documentation. If the tran

36、smitter under test is designed for operation with externally fitted encoder(s), then it is left to the decision of the manufacturer whether the transmitter under test shall be tested with such encoder(s). Depending on the manufacturers decision, the manufacturer may have to provide reference encoder

37、s and the tests shall be carried out with these in operational mode. Any unused input port of the transmitter under test shall be terminated according to the manufacturers instructions. 4.2.2 Arrangements for test signals at the input of transposers, active deflectors, or RF power amplifiers The pro

38、visions of EN 301 489-1 1, clause 4.2.2 shall apply with the following modifications. In case of transposers and active deflectors, the wanted RF input signal, at a frequency determined from the manufacturers specification, shall be set to a level equal to the mid point of the range declared by the

39、manufacturer. In case of RF amplifiers, the wanted RF input signal at a level equal to the mid point of the range declared by the manufacturer shall be delivered from an adequate external modulator provided by the manufacturer. The modulator shall be placed outside the test environment. A broadcasti

40、ng transmission shall be established at the start of the test and maintained during the test. 4.2.3 Arrangements for test signals at the output of transmitters, transposers, active deflectors or RF power amplifiers The provisions of EN 301 489-1 1, clause 4.2.3 shall apply with the following modific

41、ations. Typical test arrangements to assess the performance of the EUT are shown in: - figure 4.1 for VHF FM transmitters; - figure 4.2 for LF, MF and HF AM transmitters; - figure 4.3 for T-DAB and DRM transmitters. NOTE: In practice it is not necessary to use all the individual instrumentation show

46、 4.3.1 Transmitter and RF power amplifier exclusion band 4.3.1.1 Transmitter and RF power amplifier exclusion band for FM The exclusion band for FM broadcasting transmitters and/or power amplifiers extends from fc - 300 kHz to fc + 300 kHz, where fc is the operating frequency. 4.3.1.2 Transmitter ex

47、clusion band for AM The exclusion band for AM broadcasting transmitters shall be 500 % of the necessary bandwidth. 4.3.1.3 Transmitter exclusion band for DRM The exclusion band for DRM broadcasting transmitters shall be 500 % of the necessary bandwidth. 4.3.1.4 Transmitter and RF power amplifier exc

48、lusion band for T-DAB The exclusion band for the transmitter and/or power amplifier extends from fc- 3 MHz to fc+ 3 MHz, where fcis the operating frequency. ETSI ETSI EN 301 489-11 V1.3.1 (2006-05) 124.3.2 Active deflector exclusion band The exclusion band for the active deflector (transmitting and

49、receiving elements) is equal to the channel centre frequency -5 % to +5 %. Special precautions shall be taken to avoid the wanted RF output of the active deflector from disturbing the signal at the RF input port. 4.3.3 Transposer exclusion bands For emission measurements, the transposer exclusion band shall comprise the exclusion band of the transmitting element of the equipment under test only. For immunity tests with continuous phenomena, the transposer exclusion bands shall comprise both the exclusion bands of the transmitting and recei
