Abstract
The time required for analyzing a modulation accuracy of a modulated signal is reduced. A signal analyzing device which analyzes a signal to be measured including multiple frames each of which includes a preamble and a data symbol, includes frame acquisition units which acquire the frame from the signal to be measured, a symbol demodulation unit which demodulates the acquired frame according to symbol demodulation, and a modulation accuracy deriving unit which derives a modulation accuracy based on an output from the symbol demodulation unit, where the frame acquisition unit considers a position displaced by an integer multiple of the length of the frame from a start frame positioned at a start of the signal to be measured as a position of a subsequent frame positioned after the start frame, and acquires the subsequent frame.
