A method and system to process a spectrum of radio frequency (RF) signals. An analog to digital (A/D) converter is adapted to sample and digitize a spectrum of radio frequency (RF) signals. The spectrum of RF signals include a plurality of modulation techniques. The A/D converter is further adapted to sample the spectrum at a rate that is at least twice the frequency of the highest frequency signal that is contained within the spectrum. The digitized data stored in a memory device. A processor is adapted to process the digitized data.
