ITU-R INFORME SM.2048 SPANISH-2004 Use of the x dB bandwidth criterion for determination of spectral properties of a transmitter in the out-of-band domain
A method, used by some administrations, is described for specifying and measuring the following spectral properties of transmitters in the out-of-band (OoB) domain (§ 1.2 of Recommendation ITU-R SM.1541 refers): the bandwidth of a transmitter emission beyond which OoB emission begins, and OoB emissions as such.
