Test Select
The Test Select control sets the type of analysis to be run on the collected data set.
Control
Description
Time Domain
Runs a min / max calculation on the collected data set and then plots sample data
value vs. sample number.
Histogram
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 varys over too
many codes to plot as a histogram.
Signal FFT
Runs an FFT on the collected data set and then plots frequency magnitude vs. fre-
quency. Statistics are calculated using the largest frequency bin as a full-scale signal
reference.
Noise FFT
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.
