  • Signal analysis apparatus and signal analysis method
    Patent number: 11463285
    Abstract: A signal analysis apparatus includes a frequency conversion unit 10 that includes a first local oscillator 11 which outputs a first local oscillation signal SLO1 of a frequency fLO1, a first mixer 12 which generates a first spurious signal of a frequency fSP1, a first BPF 13 of a passed center frequency f0, a second local oscillator 14 which outputs a second local oscillation signal SLO2 of a frequency fLO2, and a second BPF 16 of a passed bandwidth W, and that performs frequency conversion of a measured signal SRF of a frequency fRF (center frequency fc), in which the frequency fLO1 and the frequency fLO2 are shifted using a frequency shift amount ?f that does not establish a relationship of ?W/2?|fSP1?f0±fIF2??f|?fIF2?+W/2.
