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 documents directly associated with the present document:
• EN 301 489-14 [5].

1 Scope
The present document applies to transmitting equipment for the analogue television broadcasting service.
The types of equipment covered by the present document are as follows:
• Television transmitter equipment for analogue television broadcasting service, with 7 MHz and 8 MHz RF
channel bandwidths, operating in the CEPT frequency bands. These frequencies are currently within the
television Bands I, III, IV and V.
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: A list of such ENs is included on the web site http://www.newapproach.org.

3 Definitions, symbols and abbreviations
3.1 Definitions
For the purposes of the present document, the following terms and definitions apply:
antenna port: port of an apparatus which is designed, in normal operation, to be connected to an antenna using coaxial
cable
analogue signal: signal in which the characteristic quantity representing information may at any instant assume any
value within a continuous interval
analogue television: television in which picture information is represented by an analogue signal
NOTE: Sound information can be represented by an analogue and/or digital signal
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
carrier power: average power supplied to the antenna port by a transmitter during one radio frequency cycle taken
under the condition of no modulation
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.
digital signal: discretely timed signal in which information is represented by a finite number of well defined discrete
values that its characteristic quantities may take in time
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: range of environmental conditions under which equipment within the scope of EN 302 297 is
required to comply with the provisions of EN 302 297
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
EXAMPLE: (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

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 taken under normal operating conditions
NOTE: For analogue television transmissions, the mean power level is defined with a specified video signal
modulation. This video signal has to be chosen in such a way that the maximum mean power level (e.g. at
the video signal blanking level for PAL) is provided to the antenna transmission line.
necessary bandwidth: for a given class of emission, the width of the frequency band which is sufficient to ensure the
transmission of information at the rate and with the quality required under specified conditions
out-of-band emissions: emission on a frequency or frequencies immediately outside the necessary bandwidth which
results from the modulation process, but excluding spurious emissions

specified conditions of operation
reference bandwidth: bandwidth in which the emission level is specified
spurious emissions: emission on a frequency or frequencies which are outside the necessary bandwidth and the level of
which may be reduced without affecting the corresponding transmission of information Spurious emissions include
harmonic emissions, parasitic emissions, intermodulation products and frequency conversion products but exclude
out-of-band emissions
television transmitter: used in EN 302 297 to refer to that equipment with a video input and one or more audio inputs
and a combined vision and sound radio frequency output
unwanted emissions: consist of spurious emissions and out-of-band emissions
letterbox operation: transmission of a picture format with an aspect ratio greater than 1,33, in such a way that empty
