3 Definitions, symbols and abbreviations
3.1 Definitions
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
cable
broadcasting service: radio communication service in which the transmissions are intended for direct reception by the
general public
NOTE: This service may include sound transmissions, television transmissions or other types of transmission.
channel L: left hand channel of a stereophonic signal
channel R: right hand channel of a stereophonic signal
cabinet radiation: radiation from an enclosure containing, equipment, excluding radiation from connected antennas or
cables
carrier power: average power supplied to the antenna port by a transmitter during one cycle taken under the condition
of no modulation
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
characteristics
composite: See "Multiplex (MPX) signal".
dBc: decibels relative to the unmodulated carrier power of the emission
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
mean power P.
difference signal : signal (S) theoretically equal to half the difference between the left (L) and right (R) stereophonic
signals. S = (L - R) / 2
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
required to comply with the provisions of EN 302 018-1
exclusion band: band of radio frequencies where no measurements are made
frequency tolerance: maximum permissible departure of the characteristic frequency of an emission from the assigned
frequency
6
NOTE: The frequency tolerance is expressed in parts per 10 or in Hz.
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
nd
(2 harmonic = 2 × 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
