2.8.10 Analyzing Data

The evaluation software provides three types of analysis tests: Time Domain, Frequency Domain, and

Histogram. The time domain analysis processes acquired conversions to produce a plot of magnitude ver-

sus conversion sample number. The frequency domain analysis processes acquired conversions to pro-

duce 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.

2.8.11 Histogram Information

The following is a description of the indicators associated with histogram analysis. Histograms can be plot-

ted in the Data Collection Window by setting the analysis type pull-down menu to Histogram.
