Electromagnetic compatibility and Radio spectrum Matters (ERM); ElectroMagnetic Compatibility (EMC) standard for radio equipment and services; Part 11: Specific conditions for terrestrial sound broadcasting service transmitters
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 A. 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.

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 transmitter 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 manufacturer's decision, the manufacturer may have to provide reference encoders 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 manufacturer's instructions. 4.2.2 Arrangements for test signals at the input of transposers, active deflectors, or RF power amplifiers The provisions 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 manufacturer's specification, shall be set to a level equal to the mid point of the range declared by the 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 broadcasting 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 modifications.

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
ETSI ETSI EN 301 489-11 V1.3.1 (2006-05) 13 - the bandwidth of the IF filter, or the bandwidth of the RF filter if no IF signal processing is used; - for RF amplifiers, the nominal level of the wanted RF input signal to be used for the EMC tests. 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.
