WebSpurious emissions measurements. Spurious emissions are undesired radio frequency emissions outside the transmission’s frequency band. These emissions can interfere with other radio services and compromise the intended transmission’s quality. Many factors can contribute to spurious emissions in a power amplifier. Web1.2 Out-of-band emission (RR Article 1, No. 1.144) Emission on a frequency or frequencies immediately outside the necessary bandwidth which results from the modulation process, but excluding spurious emissions. 1.3 Unwanted emissions (RR Article 1, No. 1.146) Consist of spurious emissions and out-of-band emissions. 1.3bis Out-of-band domain[2]

WebIn addition to the emission limits in Table 1, there are restricted frequency ranges, or bands, defined in section 15.205, in which only spurious frequencies may be produced. That is, the fundamental frequency of an intentional radiator cannot fall within one of these restricted frequency bands even if the transmit WebDefinition Spurious emissions are unwanted emissions, emanating from the equipment under test.
