2.8.1.10 Analyzing Data
The evaluation software provides three types of analysis tests: Time Domain, Frequency Domain, and Histo-
gram. The Time Domain analysis processes acquire conversions to produce a plot of magnitude versus con-
version sample number. The Frequency Domain analysis processes acquired conversions to produce a plot
of magnitude versus frequency using the Fast-Fourier transform (results up to Fs/2 are calculated and plotted).
Also statistical noise calculations are calculated and displayed. The histogram analysis processes acquired
conversions to produce a histogram plot. Statistical noise calculations are also calculated and displayed.
