The 3580A Spectrum Analyzer is a low frequency, high performance analyzer. Its 1Hz bandwidth allows the user to examine noise and extraneous signal content close in to a signal of interest. The 3580A features an adaptive sweep which allows the user to set a threshold above which only the spectra of interest are observed. Digital storage is another important feature which enhances the display for slowly swept low frequency signals.
