ABSTRACT:
A phase measurement device measures an output of an amplifier when an input signal having input frequency components is fed to the amplifier, and includes multipliers for orthogonally transforming the output of the amplifier a phase acquisition section for acquiring phases θ1and θ2of the input frequency components in the output of the multipliers, and θ3and θ4(third distortion), and θ5and θ6(fifth distortion) of the distortion components, a match time/phase measurement section for measuring a match time point Δt when θ1and θ2match each other and a distortion component phase measurement section for measuring phases θ3to θ6at the match time point Δt. The phase acquisition section acquires at least one of θ1and θ2, and θ3and θ5(with the frequencies higher than those of θ1and θ2) or θ4and θ6(with the frequencies lower than those of θ1and θ2).
