For the purposes of the present document, the following terms and definitions apply:

antenna port: port of an apparatus which is designed, in normal operation, to be connected to an antenna using coaxial

broadcasting service: radio communication service in which the transmissions are intended for direct reception by the

NOTE: This service may include sound transmissions, television transmissions or other types of transmission.

cabinet radiation: radiation from an enclosure containing, equipment, excluding radiation from connected antennas or

carrier power: average power supplied to the antenna port by a transmitter during one cycle taken under the condition

class of emission: set of characteristics of an emission, designated by standard symbols, e.g. type of modulation of the

main carrier, modulating signal, type of information to be transmitted, and also, if appropriate, any additional signal

NOTE: In the cases which do not have a carrier, for example in some digital modulation schemes where the

carrier is not accessible for measurement, the reference level equivalent to dBc is decibels relative to the

difference signal : signal (S) theoretically equal to half the difference between the left (L) and right (R) stereophonic

enclosure port: physical boundary of the apparatus through which electromagnetic fields may radiate or impinge

NOTE: In the case of integral antenna equipment, this port is inseparable from the antenna port.

environmental profile: range of environmental conditions under which equipment within the scope of EN 302 018-1 is

frequency tolerance: maximum permissible departure of the characteristic frequency of an emission from the assigned

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

harmonic number: integral number given by the ratio of the frequency of a harmonic to the fundamental frequency

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 envelope taken under normal operating conditions

MultiPleX (MPX) signal: contains all information, including the pilot tone and any supplementary signal which is
