(3)Equivalent Isotropic Radiated Power(EIRP): the product of the power supplied to the antenna and its(absolute or omni-directional)gain relative to an omni-directional antenna in a given direction.ġ8. (2)Effective Radiated Power(ERP): The product of the power supplied to the antenna and its gain relative to a half-wave dipole in a given direction. (1)Output Power: Peak envelope power measured at the output terminals of the transmitter. Transmission Power: the radio frequency power generated by an amateur radio station, measured in one of the following methods: Peak Envelope Power: 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.ġ7. Transmitter: Any type of device that is capable of converting electrical energy to electromagnetic energy, including external RF amplifiers, which may be required.ġ6. External RF Power Amplifier Kit: A package of electronic parts, which, when self-assembled pursuant to the user's manual, is an external RF power amplifier, even if additional parts are required to complete assembly.ġ5. External RF Power Amplifier: A device capable of increasing power output when used in conjunction with, but not an integral part of, a transmitter.ġ4. Antenna Structure: A generic term for a radio wave radiation system, its supporting structure and attachments.ġ3. Suppressed Carrier Single-Sideband Emission: A single-sideband emission in which the carrier is virtually suppressed and not intended to be used for demodulation.ġ2. Reduced Carrier Single-Sideband Emission: A single-sideband emission in which the degree of carrier suppression enables the carrier to be reconstituted and to be used for demodulation.ġ1. Single-sideband Emission: An amplitude modulated emission with one sideband only.ġ0. Occupied Bandwidth: The width of a frequency band such that, below its lower and above its upper frequency limits, the mean power emitted is attenuated to at least 26 dB below the total mean power of a given emission, including the frequency bandwidth within which the tolerated transmitter frequency shift and Doppler frequency shift occurs.ĩ. Spurious Emission: Radiation or frequencies outside the necessary bandwidth of a transmission, including those generated by harmonic transmission, parasitic transmission, inter-modulation and frequency conversion, the level of which may be reduced without affecting the information being transmitted, but excluding those out-of-band transmissions.Ĩ.
