3. The terms adopted herein are defined as follows:
3.1 Spurious emission: Emission on a frequency or frequencies which are outside the necessary bandwidth and the level of which may be reduced without affecting the corresponding transmission. Spurious emissions include harmonic emissions, parasitic emissions, intermodulation products and frequency conversion products, but exclude out-of-band emissions.
3.2 Out-of-band emission: Emission on a frequency or frequencies immediately outside the necessary bandwidth that results from the modulation process, but excludes spurious emissions.
3.3 Unwanted emission: Spurious emission and out-of-band emission.
3.4 Frequency tolerance: The maximum permissible departure from the center frequency of the frequency band occupied by an emission from the assigned frequency or from the characteristic frequency of an emission from the reference frequency.
3.5 Peak envelope power (PEP): The average power supplied to the antenna transmission line by a transmitter during one radio frequency cycle at the crest of the modulation envelope taken under normal operating conditions.
3.6 Output power: Peak envelope power measured at the output terminals of the transmitter.
3.7 Equivalent isotropically radiated power (EIRP): The output power when a signal is concentrated into a smaller area by the Antenna. The EIRP can take into account the losses in transmission line, connectors and includes the gain of the antenna.
