In-band spurious emission
WebIn 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. How is spurious emissions measured? Spurious emissions are measured at the base station RF output port. WebGuidance is provided for in-band, out-of-band, and spurious emission measurements.
