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 is part 2 of a multi-part deliverable covering the Electromagnetic compatibility and Radio

spectrum Matters (ERM); Transmitting equipment for the Terrestrial - Digital Audio Broadcasting (T-DAB) service, as

identified below:
Part 1: "Technical characteristics and test methods";
Part 2: "Harmonized EN under article 3.2 of the R&TTE Directive".

The present document has been produced by ETSI in response to a mandate from the European Commission issued

under Council Directive 98/34/EC [1] (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 Directive 1999/5/EC [2] 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").

Introduction

The present document is part of a set of standards designed to fit in a modular structure to cover all radio and

The left hand edge of the figure 1 shows the different clauses of article 3 of the R&TTE Directive [2].

For article 3.3 various horizontal boxes are shown. Dotted lines indicate that at the time of publication of the present

document essential requirements in these areas have to be adopted by the Commission. If such essential requirements

are adopted, and as far and as long as they are applicable, they will justify individual standards whose scope is likely to

be specified by function or interface type.

The vertical boxes show the standards under article 3.2 for the use of the radio spectrum by radio equipment. The

scopes of these standards are specified either by frequency (normally in the case where frequency bands are

harmonized) or by radio equipment type.

For article 3.1b the diagram shows EN 301 489, the multi-part product EMC standard for radio used under the EMC

Directive [3].

For article 3.1a the diagram shows the existing safety standards currently used under the LV Directive [4] and new

standards covering human exposure to electromagnetic fields. New standards covering acoustic safety may also be

required.

The bottom of the figure shows the relationship of the standards to radio equipment and telecommunications terminal

equipment. A particular equipment may be radio equipment, telecommunications terminal equipment or both. A radio

spectrum standard will apply if it is radio equipment. An article 3.3 standard will apply as well only if the relevant

essential requirement under the R&TTE Directive [2] is adopted by the Commission and if the equipment in question is

covered by the scope of the corresponding standard. Thus, depending on the nature of the equipment, the essential

requirements under the R&TTE Directive [2] may be covered in a set of standards.
The modularity principle has been taken because:

• it minimizes the number of standards needed. Because equipment may, in fact, have multiple interfaces and

functions it is not practicable to produce a single standard for each possible combination of functions that may

occur in an equipment;
• it provides scope for standards to be added:
- under article 3.2 when new frequency bands are agreed; or
- under article 3.3 should the Commission take the necessary decisions
without requiring alteration of standards that are already published;

• it clarifies, simplifies and promotes the usage of Harmonized Standards as the relevant means of conformity

assessment.

• EN 302 077-1 [5];

1 Scope

The present document applies to the following radio telecommunications terminal equipment types:

• Terrestrial - Digital Audio Broadcast equipment used in the sound broadcasting service.

NOTE 1: At the time the present document was drafted the following bands were allocated to T-DAB (Wiesbaden

agreement, Maastricht agreement (see bibliography)):
47 MHz to 68 MHz;
174 MHz to 240 MHz;
1 452 MHz to 1 492 MHz.

The present document is intended to cover the provisions of article 3.2 of Directive 1999/5/EC [2] (R&TTE Directive),

which states that "… radio equipment shall be so constructed that it effectively uses the spectrum allocated to

terrestrial/space radio communications and orbital resources so as to avoid harmful interference".

In addition to the present document, other ENs that specify technical requirements in respect of essential requirements

under other parts of article 3 of the R&TTE Directive [2] may apply to equipment within the scope of the present

document.

NOTE 2: A list of such ENs is included on the ETSI web site at http://www.etsi.org.

3 Definitions, symbols and abbreviations
3.1 Definitions

For the purposes of the present document, the terms and definitions given in the R&TTE Directive [2] and the following

apply:

antenna port: port of an apparatus which is designed, in normal operation, to be connected to an antenna using coaxial

cable

broadcasting service: radiocommunication service in which the transmissions are intended for direct reception by the

general public

NOTE: This service may include sound transmissions, television transmissions or other types of transmission.

cabinet radiation: radiation from an enclosure containing, equipment, excluding radiation from connected antennas or

cables

class of emission: set of characteristics of an emission, designated by standard symbols, e.g. type of modulation of the

main carrier, modulating signal, type of information to be transmitted, and also, if appropriate, any additional signal

characteristics
dBc: decibels relative to the unmodulated carrier power of the emission

NOTE: In the cases which do not have a carrier, for example in some digital modulation schemes where the

carrier is not accessible for measurement, the reference level equivalent to dBc is decibels relative to the

mean power P.

enclosure port: physical boundary of the apparatus through which electromagnetic fields may radiate or impinge

NOTE: In the case of integral antenna equipment, this port is inseparable from the antenna port.

environmental profile: the range of environmental conditions under which equipment within the scope of the present

document is required to comply with the provisions of the present document
exclusion band: band of radio frequencies where no measurements are made

harmonic: component of order greater than 1 of the Fourier series of a periodic quantity

harmonic number: integral number given by the ratio of the frequency of a harmonic to the fundamental frequency

(2 harmonic = 2 x fundamental frequency)

intermodulation products: unwanted frequencies resulting from intermodulation between carriers or harmonics of

emission, or between any oscillations generated to produce the carrier

L-band: for the purpose of these document L-band is defined as the frequency range from 1 452 MHz to 1 492 MHz

mean power: average power supplied to the antenna port by a transmitter during an interval of time sufficiently long

compared with the lowest frequency encountered in the modulation envelope taken under normal operating conditions
