ABSTRACT:
Apparatus for eliminating spurious spectral components from a spectral analyzer output signal. An input signal is mixed with two separate local oscillator frequencies separated by a frequency offset value to produce two intermediate-frequency signals, which are processed in spectral analyzers. The outputs of the analyzers are then compared to identify and eliminate any components that do not differ in frequency by the offset value.
