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";

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.
Other document directly associated with the present document:
• EN 302 077-1 [5];
• EN 301 489-11 [6].

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
nd
(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
