Foreword This Candidate Harmonized European Standard (Telecommunications series) has been produced by ETSI Technical Committee Electromagnetic compatibility and Radio spectrum Matters (ERM). 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 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 amended) 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&TTE Directive"). The present document is part 11 of a multi-part deliverable. Full details of the entire series can be found in part 1 [1].

1 Scope The present document, together with EN 301 489-1 [1], covers the assessment of transmitters, exciters, and any associated ancillary equipment dedicated for radio broadcasting services, in respect of ElectroMagnetic Compatibility (EMC). Technical specifications related to the antenna port emissions and cabinet radiation are not included in the present document. Such technical specifications are found in the relevant product standards of ETSI for the effective use of the radio spectrum.

The present document specifies the applicable test conditions, performance assessment and performance criteria for terrestrial sound broadcasting transmitters and their associated ancillary equipment. Definitions of the type of broadcast transmitters and exciters covered by the present document are given in annex B. In case of differences (for instance concerning special conditions, definitions, abbreviations) between the present document and EN 301 489-1 [1], the provisions of the present document take precedence. The environmental classification and the emission and immunity requirements used in the present document are as stated in EN 301 489-1 [1], except for any specific conditions included in the present document, under which broadcast service transmitters are typically used.

The present document may not cover those cases where a potential source of interference which is producing individually repeated transient phenomena or continuous phenomena is permanently present, e.g. a radar site in the near vicinity. In such a case it may be necessary to use special protection applied to either the source of interference or the interfered part or both. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. • References are either specific (identified by date of publication and/or edition number or version number) or non-specific. • For a specific reference, subsequent revisions do not apply. • For a non-specific reference, the latest version applies.

ETSI ETSI EN 301 489-11 V1.3.1 (2006-05) 12 4.3.2 Active deflector exclusion band The exclusion band for the active deflector (transmitting and 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 receiving elements of the equipment under test. The exclusion band for the transposer (transmitting and receiving elements) is equal to the channel centre frequency for each element -5 % to +5 %. For the receiver part of the transposer, the exclusion band takes into account the blocking effect that may occur due to the high level of the immunity test fieldstrength (10 V/m) in regard to the RF input level of that receiver part (which is usually less than 1 mV). 4.4 Narrow band responses of receivers The provisions of EN 301 489-1 [1], clause 4.4 shall apply during the immunity tests of transposers and active deflectors to continuous phenomena. 4.5 Normal test modulation For the purpose of EMC tests, the transmitter under test shall be modulated according to the normal test modulation as specified below: - FM: 1 kHz audio tone of sufficient amplitude to achieve ±50 kHz deviation. - AM: 1 kHz audio tone of sufficient amplitude to achieve 80 % modulation depth. - For T-DAB and DRM transmitters with audio encoders the audio input port should be terminated (i.e. no modulating signal). - For T-DAB transmitters without an audio encoder a datastream conforming to ETS 300 799 [9] shall be presented to the MPX input. - For DRM transmitters without an audio encoder a datastream conforming to TS 102 820 [10] shall be presented to the MPX input. The characteristics of the wanted RF and modulation test signal used shall be recorded in the test report. 5 Performance assessment 5.1 General The provisions of EN 301 489-1 [1], clause 5.1 shall apply.

In addition, the manufacturer shall, at the time of submission of the equipment for testing, declare the following information, also to be recorded in the test report, as appropriate: - the frequencies as used in the transmitter for oscillators, clocks and intermediate frequencies; SIST EN 301 489-11 V1.3.1:2006

For transmitters supplied for testing, which do 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), for inclusion in the product documentation. The manufacturer shall declare whether the EMC tests shall be performed with external encoder(s) fitted to the transmitter.

5.2 Equipment which can provide a continuous communication link as a broadcasting transmission The provisions of EN 301 489-1 [1], clause 5.2 shall apply. 5.3 Equipment which does not provide a continuous communication link as a broadcasting transmission Not applicable. 5.4 Ancillary equipment The provisions of EN 301 489-1 [1], clause 5.4 shall apply. 5.5 Equipment classification Unless specified otherwise in clauses 7.1.2 and/or 7.2.2 of the present document, broadcasting service transmitters and associated ancillary equipment in the scope of the present document shall meet the requirements for base station and ancillary equipment set out in EN 301 489-1 [1], clauses 7.8 and 9. 6 Performance criteria The provisions of EN 301 489-1 [1], clause 6 shall apply. 6.1 Performance criteria for continuous phenomena applied to transmitters (CT) The provisions of EN 301 489-1 [1], clause 6.1 shall apply with the following modifications. A broadcasting transmission link shall be established between the EUT and the monitoring equipment at the start of the test, and maintained during the test. The parameters specified in table 6.1 shall be used to assess the performance of the Tx under test for continuous phenomena. During each individual exposure in the test sequence, it shall be verified that the characteristics of the wanted output signals remain within the permitted value ranges listed in table 6.1. The performance of the Tx under test shall be assessed during the exposure with error correction activated and/or pre-emphasis and de-emphasis inserted into the transmission line, if appropriate.
