2.8.1.9 Collecting Data Sets
To collect a sample data set:
1. In the Data Collection window, click the Config button to bring up the Configuration window and view

4. Once the data has been collected, it can be analyzed, printed, or saved to disk.
2.8.1.10 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.
