SPECTRUM ANALYZER SCREEN

SPECTRUM Analyzer screen is used to visualize the spectral analysis of the input signal.

Spectral components of the selected signal are determined on the base of Fast Fourier Transform.

Possible signal Sources are MPX, Left and Right. Possible Window Functions are Rectangle,

Bartlett, Blackman, Hamming, Hanning, Kaiser, Flat-top.

User-defined frequency from the spectrum can be selected by moving vertical marker along the

horizontal scale. Values at the cross-point will be shown at top right corner of the graph.
