WebSpurious emission search with spectrum analyzers is an essential measurement in the design, verification and production of RF and microwave devices. Manufactures of all kinds of RF and microwave transmitters such as radars, satellite up- and down-converters need to ensure that their equipment spurious emissions are within the specified limits.

In radio communication, a spurious emission is any component of a radiated radio frequency signal the complete suppression of which would not impair the integrity of the modulation type or the information being transmitted. A radiated signal outside of a transmitter's assigned channel is an example of a spurious emission.
