• The Min Code, Max Code, and Mean Code indicators display the minimum, maximum and average
value of the captured data set.
• The Code Spread column shows the peak-to-peak spread of the codes in the data set.
• The Sigma indicator displays standard deviation of the data set. This value is equivalent to the RMS
noise of the signal when analyzing a dc data set.
