1 Scope
The present document specifies technical characteristics and methods of measurements for digital terrestrial television
transmitters as defined in table 1.1 and in table 1.2. The power classification (table 1.1) and emission classification
(table 1.2) are combined to define a transmitter category. For example, power classification H and emission
classification 0 denote a high power transmitter (category H0) whose OOB emissions comply with a non-critical mask.
Table 1.1: Transmitter power classification
Power Class Description Notes
H High power transmitter Transmitter with an output power ≥ 25 W operating in the
VHF band (174 MHz to 230 MHz) or UHF band (470 MHz to
694 MHz).
L Low power transmitter Transmitter with an output power < 25 W operating in the
VHF band (174 MHz to 230 MHz) or UHF band (470 MHz to
694 MHz).
Table 1.2: Transmitter emission classification
Emission
Conformance approach Notes
Classification
0 Non-critical mask For high power transmitters, the mask defines the level of
the OOB emissions relative to the channel power (dBc). For
low power transmitters the mask defines the absolute power
limit of the OOB emissions (dBm). The former approach is
mandated by RRC-06 (non-critical case) [i.4] for transmitters
subject to coordination.
1 Critical mask A similar but more stringent approach based on ITU RRC-06
(sensitive case) [i.4].
2 Non-critical ACLR A set of ACLR limits defining permitted relative emission
levels into adjacent channels.
3 Critical ACLR A set of more stringent ACLR limits defining permitted
relative emission levels into adjacent channels.
NOTE: The relationship between the present document and essential requirements of article 3.2 of Directive
2014/53/EU [i.2] is given in annex A.

1 Scope
The present document specifies technical characteristics and methods of measurements for digital terrestrial television
transmitters as defined in table 1.1 and in table 1.2. The power classification (table 1.1) and emission classification
(table 1.2) are combined to define a transmitter category. For example, power classification H and emission
classification 0 denote a high power transmitter (category H0) whose OOB emissions comply with a non-critical mask.
Table 1.1: Transmitter power classification
Power Class Description Notes
H High power transmitter Transmitter with an output power ≥ 25 W operating in the
VHF band (174 MHz to 230 MHz) or UHF band (470 MHz to
694 MHz).
L Low power transmitter Transmitter with an output power < 25 W operating in the
VHF band (174 MHz to 230 MHz) or UHF band (470 MHz to
694 MHz).
Table 1.2: Transmitter emission classification
Emission
Conformance approach Notes
Classification
0 Non-critical mask For high power transmitters, the mask defines the level of
the OOB emissions relative to the channel power (dBc). For
low power transmitters the mask defines the absolute power
limit of the OOB emissions (dBm). The former approach is
mandated by RRC-06 (non-critical case) [i.4] for transmitters
subject to coordination.
1 Critical mask A similar but more stringent approach based on ITU RRC-06
(sensitive case) [i.4].
2 Non-critical ACLR A set of ACLR limits defining permitted relative emission
levels into adjacent channels.
3 Critical ACLR A set of more stringent ACLR limits defining permitted
relative emission levels into adjacent channels.
NOTE: The relationship between the present document and essential requirements of article 3.2 of Directive
2014/53/EU [i.2] is given in annex A.

1 Scope
The present document specifies technical characteristics and methods of measurements for digital terrestrial television
transmitters as defined in table 1.1 and in table 1.2. The power classification (table 1.1) and emission classification
(table 1.2) are combined to define a transmitter category. For example, power classification H and emission
classification 0 denote a high power transmitter (category H0) whose OOB emissions comply with a non-critical mask.
Table 1.1: Transmitter power classification
Power Class Description Notes
H High power transmitter Transmitter with an output power ≥ 25 W operating in the
VHF band (174 MHz to 230 MHz) or UHF band (470 MHz to
694 MHz).
L Low power transmitter Transmitter with an output power < 25 W operating in the

1 Scope
The present document specifies technical characteristics and methods of measurements for digital terrestrial television
transmitters as defined in table 1.1 and in table 1.2. The power classification (table 1.1) and emission classification
(table 1.2) are combined to define a transmitter category. For example, power classification H and emission
classification 0 denote a high power transmitter (category H0) whose OOB emissions comply with a non-critical mask.
Table 1.1: Transmitter power classification
Power Class Description Notes
H High power transmitter Transmitter with an output power ≥ 25 W operating in the
VHF band (174 MHz to 230 MHz) or UHF band (470 MHz to
694 MHz).
L Low power transmitter Transmitter with an output power < 25 W operating in the
VHF band (174 MHz to 230 MHz) or UHF band (470 MHz to
694 MHz).
Table 1.2: Transmitter emission classification
Emission
Conformance approach Notes
Classification
0 Non-critical mask For high power transmitters, the mask defines the level of
the OOB emissions relative to the channel power (dBc). For
low power transmitters the mask defines the absolute power
limit of the OOB emissions (dBm). The former approach is
mandated by RRC-06 (non-critical case) [i.4] for transmitters
subject to coordination.
1 Critical mask A similar but more stringent approach based on ITU RRC-06
(sensitive case) [i.4].
2 Non-critical ACLR A set of ACLR limits defining permitted relative emission
levels into adjacent channels.
3 Critical ACLR A set of more stringent ACLR limits defining permitted
relative emission levels into adjacent channels.
NOTE: The relationship between the present document and essential requirements of article 3.2 of Directive
2014/53/EU [i.2] is given in annex A.

1 Scope
The present document specifies technical characteristics and methods of measurements for digital terrestrial television
transmitters as defined in table 1.1 and in table 1.2. The power classification (table 1.1) and emission classification
(table 1.2) are combined to define a transmitter category. For example, power classification H and emission
classification 0 denote a high power transmitter (category H0) whose OOB emissions comply with a non-critical mask.
Table 1.1: Transmitter power classification
Power Class Description Notes
H High power transmitter Transmitter with an output power ≥ 25 W operating in the
VHF band (174 MHz to 230 MHz) or UHF band (470 MHz to
694 MHz).
L Low power transmitter Transmitter with an output power < 25 W operating in the
VHF band (174 MHz to 230 MHz) or UHF band (470 MHz to
694 MHz).
Table 1.2: Transmitter emission classification
Emission
Conformance approach Notes
Classification
0 Non-critical mask For high power transmitters, the mask defines the level of
the OOB emissions relative to the channel power (dBc). For
low power transmitters the mask defines the absolute power
limit of the OOB emissions (dBm). The former approach is
mandated by RRC-06 (non-critical case) [i.4] for transmitters
subject to coordination.
1 Critical mask A similar but more stringent approach based on ITU RRC-06
(sensitive case) [i.4].
2 Non-critical ACLR A set of ACLR limits defining permitted relative emission
levels into adjacent channels.
3 Critical ACLR A set of more stringent ACLR limits defining permitted
relative emission levels into adjacent channels.
NOTE: The relationship between the present document and essential requirements of article 3.2 of Directive
2014/53/EU [i.2] is given in annex A.
