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.

For the purposes of the present document, the terms given in Directive 2014/53/EU [i.2] and the following apply:

adjacent channel leakage ratio: ratio of the wanted mean power of the DVB-T/T2 signal to the unwanted mean power

antenna port: port of an apparatus intended to be connected to an antenna using coaxial cable or coaxial line; typically

carrier power: mean power supplied to the antenna port by a transmitter with COFDM

channel bandwidth: frequency band of defined width (as a multiple of the carrier grid) for operation on adjacent

composite approach: measurement method whereby the power amplifier emissions are measured separately to the

frequency response of subsequent frequency selective components and the overall emissions of the transmitter are

co-sited: DVB-T/T2 transmitters which are located at the same physical site so minimizing the effects of adjacent

digital signal: discretely timed signal in which information is represented by a finite number of well-defined discrete

digital television: television in which all information is represented by a digital signal

environmental profile: range of environmental conditions under which equipment is expected to operate within the

harmonic: component of order greater than 1 of the Fourier series of a periodic quantity

high power transmitter: transmitter whose output power is greater than or equal to 25 W

NOTE: This category of transmitter also includes medium power category of transmitters as defined in ITU-R.

intermodulation products: unwanted frequencies resulting from intermodulation between carriers or harmonics of

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

moding: operation of a coaxial component in unwanted waveguide modes (e.g. Transverse Electric (TE) or Transverse

Magnetic (TM)) resulting in anomalous behaviour from that associated with the intended Transverse Electromagnetic

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

OOB emissions: unwanted emissions which fall at frequencies separated from the centre frequency of the wanted

output power: conducted power delivered by a transmitter under specified conditions of operation

receiver bandwidth: bandwidth used for victim service ACLR measurements, i.e. 7,6 MHz for 8 MHz DVB-T,

6,7 MHz for 7 MHz DVB-T, 7,8 MHz for 8 MHz DVB-T2, 6,8 MHz for 7 MHz DVB-T2 and 9 MHz for LTE

spurious domain emissions: unwanted emissions at frequencies separated by more than 250 % of the channel

For the purposes of the present document, the abbreviations given in ETSI EN 300 744 [i.5], ETSI EN 302 755 [i.6] and

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 essential parameters and corresponding technical requirements aiming to meet the requirements of article 3.2 of

Directive 2014/53/EU [i.2] are shown in table 4.1. To fulfil this essential parameter the compliance with all the

Both spurious emission limits and OOB limits are defined in terms of output power at the antenna port.

The boundary between spurious domain emissions and out-of-band emissions is shown in figure 4.1.

Spurious emissions are unwanted emissions at frequencies separated by more than 250 % of the channel bandwidth
