1 Scope
The present document specifies technical characteristics and methods of measurements for transmitting equipment for
broadcast sound services using the Digital Audio Broadcast (DAB) modulation system operating in VHF band III
(174 MHz to 240 MHz).
DAB transmissions are licensed by national administrations. The Final Acts of the CEPT T-DAB Planning Meeting
Constanţa, 2007 (WI95revCO07) [i.2] and the Final Acts of the Regional Radiocommunication Conference for planning
of the digital terrestrial broadcasting service in parts of Regions 1 and 3, in the frequency bands 174 MHz to 230 MHz
and 470 MHz to 862 MHz (RRC-06) [i.3] provide spectrum masks for Out-of-Band emissions under different
conditions. These requirements are represented by four transmission cases in the present document, see table 0. The
license conditions set by the national administration stipulate which transmission case (Out-of-Band spectrum mask)
applies.
Table 0: Transmission cases
Case Description Identification in Identification in RRC-06
WI95revCO07
1 Applicable to DAB transmissions operating in areas 1: critical 2: sensitive
critical for adjacent channel DAB to DAB interference,
and in any case when it is necessary to protect other
services operating on adjacent frequencies on a primary
basis
2 Applicable to DAB transmissions when no other case 2: non-critical 1: non-critical
applies
3 Applicable to DAB transmitters in exceptional Critical case considering
circumstances to protect safety services protection of distress
and safety frequencies
4 Applicable to DAB transmissions operating on a 3: sensitive in certain
case-by-case basis in certain areas areas where channel 12D
is in use

NOTE: The relationship between the present document and essential requirements of article 3.2 of
Directive 2014/53/EU [i.1] is given in annex A.

1 Scope
The present document specifies technical characteristics and methods of measurements for transmitting equipment for
broadcast sound services using the Digital Audio Broadcast (DAB) modulation system operating in VHF band III
(174 MHz to 240 MHz).
DAB transmissions are licensed by national administrations. The Final Acts of the CEPT T-DAB Planning Meeting
Constanţa, 2007 (WI95revCO07) [i.2] and the Final Acts of the Regional Radiocommunication Conference for planning
of the digital terrestrial broadcasting service in parts of Regions 1 and 3, in the frequency bands 174 MHz to 230 MHz
and 470 MHz to 862 MHz (RRC-06) [i.3] provide spectrum masks for Out-of-Band emissions under different
conditions. These requirements are represented by four transmission cases in the present document, see table 0. The
license conditions set by the national administration stipulate which transmission case (Out-of-Band spectrum mask)
applies.
Table 0: Transmission cases
Case Description Identification in Identification in RRC-06
WI95revCO07
1 Applicable to DAB transmissions operating in areas 1: critical 2: sensitive
critical for adjacent channel DAB to DAB interference,
and in any case when it is necessary to protect other
services operating on adjacent frequencies on a primary
basis
2 Applicable to DAB transmissions when no other case 2: non-critical 1: non-critical
applies
3 Applicable to DAB transmitters in exceptional Critical case considering
circumstances to protect safety services protection of distress
and safety frequencies
4 Applicable to DAB transmissions operating on a 3: sensitive in certain
case-by-case basis in certain areas areas where channel 12D
is in use

NOTE: The relationship between the present document and essential requirements of article 3.2 of
Directive 2014/53/EU [i.1] is given in annex A.

Foreword
This draft Harmonised European Standard (EN) has been produced by ETSI Technical Committee Electromagnetic
compatibility and Radio spectrum Matters (ERM), and is now submitted for the combined Public Enquiry and Vote
phase of the ETSI standards EN Approval Procedure.
The present document has been prepared under the Commission's standardisation request C(2015) 5376 final [i.4] to
provide one voluntary means of conforming to the essential requirements of Directive 2014/53/EU on the harmonisation
of the laws of the Member States relating to the making available on the market of radio equipment and repealing
Directive 1999/5/EC [i.1].
Once the present document is cited in the Official Journal of the European Union under that Directive, compliance with
the normative clauses of the present document given in table A.1 confers, within the limits of the scope of the present
document, a presumption of conformity with the corresponding essential requirements of that Directive, and associated
EFTA regulations.

Proposed national transposition dates
Date of latest announcement of this EN (doa): 3 months after ETSI publication
Date of latest publication of new National Standard
or endorsement of this EN (dop/e): 6 months after doa
Date of withdrawal of any conflicting National Standard (dow): 18 months after doa

1 Scope
The present document specifies technical characteristics and methods of measurements for transmitting equipment for
broadcast sound services using the Digital Audio Broadcast (DAB) modulation system operating in VHF band III
(174 MHz to 240 MHz).
DAB transmissions are licensed by national administrations. The Final Acts of the CEPT T-DAB Planning Meeting
Constanţa, 2007 (WI95revCO07) [i.2] and the Final Acts of the Regional Radiocommunication Conference for planning
of the digital terrestrial broadcasting service in parts of Regions 1 and 3, in the frequency bands 174 MHz to 230 MHz
and 470 MHz to 862 MHz (RRC-06) [i.3] provide spectrum masks for Out-of-Band emissions under different
conditions. These requirements are represented by four transmission cases in the present document, see table 0. The
license conditions set by the national administration stipulate which transmission case (Out-of-Band spectrum mask)
applies.
Table 0: Transmission cases
Case Description Identification in Identification in RRC-
WI95revCO07 06
1 Applicable to DAB transmissions operating in areas critical 1: critical 2: sensitive
for adjacent channel DAB to DAB interference, and in any
case when it is necessary to protect other services
operating on adjacent frequencies on a primary basis
2 Applicable to DAB transmissions when no other case 2: non-critical 1: non-critical
applies
3 Applicable to DAB transmitters in exceptional Critical case considering
circumstances to protect safety services protection of distress and
safety frequencies
4 Applicable to DAB transmissions operating on a case-by- 3: sensitive in certain
case basis in certain areas areas where channel
12D is in use

NOTE: The relationship between the present document and essential requirements of article 3.2 of
Directive 2014/53/EU [i.1] is given in annex A.
