Digitalni prizemni TV-oddajniki - Harmonizirani standard, ki zajema bistvene zahteve člena 3.2 direktive 2014/53/EU
Ta dokument določa tehnične lastnosti in merilne metode za digitalne prizemne TV-oddajnike, kot so opredeljeni v preglednicah 1.1 in 1.2. Razvrstitev izhodne moči (preglednica 1.1) in razvrstitev emisij (preglednica 1.2) sta združeni in določata kategorijo oddajnika. Na primer razvrstitev moči H in emisij 0 označuje močan oddajnik (kategorija H0), katerega emisije OOB so v skladu z nekritično masko.

SIST EN 302 296 V2.1.1:2017
ETSI ETSI EN 302 296 V2.1.1 (2017-06) 6 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 output 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 denotes 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 Classification Conformance approach Notes 0 Non critical mask For high power transmitters, the mask defines the level of the OOB relative to the channel power (dBc). For low power transmitters the mask defines the absolute power limit of the OOB (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 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.

To fulfil this essential parameter the compliance with all the corresponding technical requirements in table 4.1 shall be verified. Table 4.1: Cross references Essential parameter Corresponding technical requirements Conducted emissions at the antenna port
4.2.2 Spurious emissions 4.2.3 Out-of-band emissions (OOB)
Both spurious emission limits and OOB limits are defined in terms of conducted power at the antenna port. The boundary between spurious domain emissions and out-of-band emissions is shown in figure 4.1.
Figure 4.1: Definition of out-of-band and Spurious Domains 4.2.2 Spurious emissions 4.2.2.1 Definition Spurious emissions are unwanted emissions at frequencies separated by more than 250 % of the channel bandwidth from the centre of the occupied spectrum. These include harmonic emissions, parasitic emissions, intermodulation products and frequency conversion products but exclude out-of-band emissions. For the purposes of the present document spurious emissions are emissions at frequencies outside the frequency range
f0 ± 17,5 MHz for 7 MHz channels, f0 ± 20 MHz for 8 MHz channels, where f0 is the centre frequency of the channel, irrespective of the number of carriers employed.

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 output 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 denotes 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 relative to the channel power (dBc). For low power
transmitters the mask defines the absolute power limit of the
OOB (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 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.
The present document covers the essential requirements of article 3.2 of Directive 2014/53/EU [i.2] under the
conditions identified in annex A.

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

The technical requirements of the present document apply under the environmental profile for operation of the
equipment, which shall be declared by the manufacturer. The equipment shall comply with all the technical
requirements of the present document which are identified as applicable in annex A at all times when operating within
the boundary limits of the declared operational environmental profile.
4.2 Conformance requirements
4.2.1 Introduction
The essential parameters and corresponding technical requirements aiming to meet the requirements of article 3.2 of

Spurious emissions are unwanted emissions at frequencies separated by more than 250 % of the channel bandwidth
from the centre of the occupied spectrum. These include harmonic emissions, parasitic emissions, intermodulation

Foreword
This draft Harmonised European Standard (EN) has been produced by ETSI Technical Committee Electromagnetic

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.3] 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.2].
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

Introduction
The present document has been produced to update the existing standard in line with the requirements of article 3.2 of
Directive 2014/53/EU [i.2].

1 Scope
The present document applies to categories of digital terrestrial television transmitter defined according to table 1.1 and
table 1.2. The output 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 denotes 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 ≥ 25W 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 < 25W 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 relative to the channel power (dBc). For low power
transmitters the mask defines the absolute power limit of the
OOB (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 RRC-06
(sensitive case).
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.
The present document contains requirements to demonstrate that radio equipment both effectively uses and supports the
efficient use of radio spectrum in order to avoid harmful interference.
