Description

Runs a min / max calculation on the collected data set and then plots sample data

value vs. sample number.

Runs a histogram calculation on the collected data set and then plots sample occur-

rence vs. sample value. Only valid for noise data since sine wave data varies over

too many codes to plot as a histogram.

Runs an FFT on the collected data set and then plots frequency magnitude vs. fre-

quency. Statistics are calculated using the largest frequency magnitude bin as a full-

scale signal reference.

Runs an FFT on the collected data set and then plots frequency magnitude vs. fre-

quency. Statistics are calculated using a simulated full-scale signal as a full-scale sig-

nal reference.

Runs an FFT on the collected data set and then plots phase vs. frequency. Limited

usefulness for real collected data since noise has random phase.
