In-band spurious emission
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. Web1.6 Unwanted emissions Consist of spurious emissions and out-of-band emissions (RR Article 1, No. 140). For DRRS an example of a typical scenario is reported in Fig. 2. 1.7 Out-of-band emission Emission on a frequency or frequencies immediately outside the necessary bandwidth which results from the modulation process, but excluding spurious ...

A radiated signal outside of a transmitter's assigned channel is an example of a spurious emission. Spurious emissions can include harmonic emissions, intermodulation products and frequency conversion products.
