Device, method, and program for measuring signal, and recording medium
First Claim
1. A signal measuring device for measuring signals which are generated by modulating frequency-different signals that are different in frequency from each other, and are respectively output from different output terminals, comprising:
- a combiner that combines the signals that are respectively output from the different output terminals;
a demodulator that demodulates a result of combining carried out by the combiner;
a measurer that measures measured data for respective frequencies of a result of demodulation carried out by the demodulator;
a corresponding data acquirer that acquires output-terminal-corresponding data, which corresponds to the different output terminals, based on the measured data;
a characteristic deriver that derives characteristics of the different output terminals based on the output-terminal-corresponding data; and
a difference acquirer that acquires a difference in the characteristics between the different output terminals based on the characteristics derived by the characteristic deriver.

Abstract
Differences in outputs from multiple terminals are easily measured. There is provided a signal measuring device for receiving signals to be measured which are generated by modulating frequency-different signals different in frequency from each other, and are respectively output from different output terminals, including a combiner which combines the signals to be measured output from the output terminals, a quadrature demodulation unit which demodulates a result of the combining carried out by the combiner, an FFT unit which represents a result of the demodulation in the frequency domain, and a characteristic measuring unit, where the characteristic measuring unit measures data for respective frequencies of the result of the demodulation, acquires output-terminal-corresponding data, which correspond to the respective output terminals, based on the data, derives characteristics of the respective output terminals based on the output-terminal-corresponding data, and acquires a difference in the characteristics between the output terminals based on the derived result.
