Page 87 FFT Mode • P.S.D. (Power Spectrum Density) The "Power Spectrum Density" refers to the power spectrum per unit frequency. The result of FFT analysis is an integral value of the power spectrum that is distributed along a bandwidth (the width of the frequency resolution) that is determined by the selected frequency for FFT analysis (the Frequency setting) and the selected number of points to be analyzed (the Counts setting).
Page 88 – The Phase value is identical to that of Phase Value of the Cross Spectrum setting shown in the preceding table. – In the WR300's FFT mode, the CH.A and CH.B parameters correspond to X(i) and Y(i), respectively. • Coherence (Coherence function)
