Claim:
1. A system configured to process an electrical signal, comprising: an analog to digital converter (ADC) configured to digitize the electrical signal to produce a stream of digitized data in the time domain, wherein the stream has an original frequency spectrum, wherein the ADC provides the stream to N signal paths N signal paths (N>1) each configured to down-convert and filter the stream to produce N streams of digitized data in the time domain, wherein the N streams have N frequency spectra, respectively, and the N frequency spectra cover N different portions of the frequency spectrum, respectively; N different real-time spectrum analyzer (RTSA) engines configured to process the N streams to produce N RTSA outputs by performing a Fourier transform on each of the streams; and identifying overlapping frequency bins between different streams among the N streams; a display configured, to display the N RTSA outputs concurrently on a single RTSA display, wherein an alignment of the different streams within the RTSA display is determined according to the overlapping frequency bins.
