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 Classification; Conformance approach; Notes 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) for transmitters subject to coordination. 1; Critical mask; A similar but more stringent approach based on ITU 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. NOTE: The relationship between the present document and essential requirements of article 3.2 of Directive 2014/53/EU is given in annex A.
