The evaluation software provides three types of analysis - time domain, frequency domain, and histogram.
The time domain analysis processes acquired conversions to produce a plot of conversion sample num-
ber 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 test
processes acquired conversions to produce a histogram plot. Statistical noise calculations are also calcu-
lated and displayed.
