Abstract:
A signal generator includes inverse characteristic calculation means for calculating an inverse characteristic of a transfer function from an inverse characteristic of a frequency characteristic of a signal based on the transmission standard, inverse Fourier transform means for calculating impulse responses of a plurality of points by performing inverse Fourier transform on the inverse characteristic of the transfer function, impulse response cutout means for cutting out the points for a predetermined number of taps from the impulse response, frequency characteristic calculation means for calculating a frequency characteristic based on values of the points for the number of taps cut out from the impulse response, and display control means for displaying on a display screen, the frequency characteristic calculated by the frequency characteristic calculation means and an ideal frequency characteristic read from an S parameter file of a device under test.
