The evaluation software provides three types of analysis - Time Domain, Frequency Domain, and Histo-
gram. The Time Domain analysis processes acquired conversions to produce a plot of conversion sample
number versus magnitude. The Frequency Domain analysis processes acquired conversions to produce
a magnitude-versus-frequency plot using the Fast-Fourier transform (results up to Fs/2 are calculated and
plotted). Also, performance parameters are also calculated and displayed. The Histogram analysis pro-
cesses acquired conversions to produce a histogram plot. Statistical noise calculations are also calculat-
ed and displayed. For more information on Histograms, refer to Application Note
Analysis”.
