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: radiocommunication 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.
cabinet radiation: radiation from an enclosure containing, equipment, excluding radiation from connected antennas or
cables
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
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.
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 302 077-1 is
required to comply with the provisions of EN 302 077-1
exclusion band: band of radio frequencies where no measurements are made
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 x fundamental frequency)
intermodulation products: unwanted frequencies resulting from intermodulation between carriers or harmonics of
emission, or between any oscillations generated to produce the carrier
L-band: for the purpose of these document L-band is defined as the frequency range from 1 452 MHz to 1 492 MHz
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
necessary bandwidth: for a given class of emission, the width of the frequency band which is sufficient to ensure the
transmission of information at the rate and with the quality required under specified conditions
out-of-band emissions: emission on a frequency or frequencies immediately outside the necessary bandwidth which
results from the modulation process, but excluding spurious emissions
rated output power: power that the transmitter or transposer shall deliver at its output under specified conditions of
operation
reference bandwidth: bandwidth in which the emission level is specified

RMS power: the apparent power of an AC power that is calculated by multiplying root-mean-square (rms) current by
the root mean square voltage
NOTE 1: In a purely resistive circuit this is held to be the equivalent heating effect of a DC power and can be
deemed to be true power. In a circuit that consists of reactance as well as resistance the apparent power is
greater than the true power (the vector difference between true power and apparent power is called
reactive power).
True Power = Vrms x (Irms ∆ cos Ø)
Where Δ cos Ø is the phase difference between voltage and current introduced by the reactance of the
load.
NOTE 2: From the above definition it becomes clear that unless any measuring system can be completely devoid of
reactance then the measured power cannot be considered to be RMS power. It therefore becomes apparent
that this parameter would be difficult to measure with any degree of accuracy at RF frequencies.
spurious emissions: emissions on a frequency or frequencies which are outside the necessary bandwidth and the level
of which may be reduced without affecting the corresponding transmission of information. Spurious emissions include
harmonic emissions, parasitic emissions, intermodulation products and frequency conversion products but exclude out
of band emissions.
unwanted emissions: consist of spurious emissions and out-of-band emissions
