Overview

SIST EN 301 489-14 V1.2.1:2004 establishes the electromagnetic compatibility (EMC) requirements specific to analogue and digital terrestrial TV broadcasting service transmitters. As part of a multi-part series aimed at harmonizing EMC standards for radio equipment and services, this standard outlines necessary test conditions, performance criteria, and applicability for transmitters, exciters, and associated ancillary equipment used in terrestrial television broadcasting. Its primary purpose is to ensure that such broadcasting equipment operates without causing or being susceptible to electromagnetic interference, thereby safeguarding the reliability and quality of TV broadcast services.

Key Topics

• EMC Requirements: The standard defines the minimum levels of electromagnetic emissions and immunity for analogue and digital terrestrial TV transmitters, including arrangements for testing with both integrated and external encoding equipment.
• Test Conditions: It specifies detailed test setups for both analogue and digital transmitters, including procedures for signal injection, monitoring, and the handling of unique broadcasting components such as transposers and active deflectors.
• Performance Assessment: The standard lays out requirements for assessing equipment performance during exposure to continuous and transient electromagnetic phenomena, ensuring consistent broadcast quality.
• Special Conditions: Specific EMC emission and immunity criteria are tailored to the broadcast environment, including considerations for high-power equipment, AC and DC power inputs, and RF port emissions.
• Compliance Procedures: Equipment under test must establish and maintain a broadcasting transmission link during EMC tests, with various measured parameters required to remain within permitted ranges, and procedures for the assessment of control functions and data integrity after testing.

Applications

SIST EN 301 489-14 V1.2.1:2004 is crucial for:

• Manufacturers of TV broadcasting transmitters and ancillary equipment to ensure their products meet European EMC regulations.
• Testing Laboratories performing conformity assessments on radio transmission equipment for terrestrial TV.
• Broadcasters and System Integrators establishing or upgrading terrestrial TV transmission networks, ensuring interference-free operation alongside other radio services.
• Regulatory Compliance: Satisfying legal requirements for CE marking under the EMC Directive and Radio Equipment Directive.
• Product Development: Guiding the design and documentation processes for new broadcasting equipment to minimize expenses related to post-production compliance modifications.

The standard applies to a range of broadcasting service equipment, including:

• Analogue TV transmitters and associated devices (active deflectors, transposers)
• Digital TV (T-DVB) transmitters and related RF amplification and modulation systems
• Broadcasting devices operating in the frequency ranges of 174 MHz to 230 MHz and 470 MHz to 860 MHz

By adhering to this standard, stakeholders can ensure high-quality, interference-free TV broadcast delivery, essential for public service broadcasting and commercial TV operators.

Related Standards

Organizations and professionals involved in EMC compliance for broadcasting equipment should also reference the following related standards and documents:

• EN 301 489-1: General requirements for electromagnetic compatibility and radio spectrum matters for radio equipment and services
• EN 55011: Limits and methods of measurement of radio disturbance characteristics for ISM (Industrial, Scientific and Medical) equipment
• EN 300 744: Digital Video Broadcasting (DVB) – Framing structure, channel coding, and modulation for digital terrestrial TV
• EN 61000-4-3: EMC immunity testing for radiated, radio-frequency, electromagnetic fields
• ITU-R BT.500: Methodology for subjective assessment of the quality of television pictures

These standards provide a comprehensive framework for EMC testing, emissions control, and product conformity for manufacturers and technical service providers in the broadcasting industry.

1 Scope The present document, together with EN 301 489-1 [1], covers the assessment of analogue and digital transmitters, exciters, and any associated ancillary equipment dedicated for television 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 analogue and digital terrestrial television 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 a 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.
