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.

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.
