Octave Band Analyzer

Need to see your signal's spectrum in true fractional octave bands?  SignalScope Pro enables real-time CPB (constant percentage band) spectral analysis with its Octave Analyzer.

Select either whole octave or third octave spectral analysis, and SignalScope Pro computes the spectrum with digital Butterworth filters, as recommended by ANSI standards.  The spectral values are determined using the standard time weightings employed by sound level meters, and you can even measure calibrated sound levels in octave or third octave bands.

Use the dual cursors to precisely measure time-weighted or equivalent signal levels (including current, peak, and max values) in any available frequency band, or measure the difference in signal levels between two frequencies.
