PROBLEM TO BE SOLVED: To supply a frequency analysis system with a test signal which is sent from a test signal source and expressed by a first transfer function G(w), and to obtain a second transfer function F(w), independently of the first transfer function G(w). SOLUTION: A first measurement data set is acquired, while supplying the frequency analysis system 20 with a first test signal from the test signal source 10, and a second measurement data set is acquired, while supplying the frequency analysis system 20 with a second test signal obtained by shifting the first test signal by a known frequency value. When the corresponding data of the first and second measurement data sets are compared, although it is recognized that G(w) components are identical, F(w) components are different in the first and second measurement data sets. This characteristic is utilized, and the G(w) components are canceled out, by carrying out calculations using the first and second data sets, thereby the second transfer function F(w) is calculated, independently of the first transfer function G(w).
