Statistics

The Statistics control displays calculated statistics for the selected analysis channel. For multichannel
data captures, only one channel of calculated statistics are displayed at a time and is selected using the
Statistics channel control.

Errors that affect statistical calculations will cause the Plot Error control to appear. Information about er-
rors on specific channels can be accessed by enabling the plot of the channel using the Plot Enable con-
trol and then accessing the Plot Error controls.

3.4.3

Plot Enable

The Plot Enable control selects which channels are plotted for the current analysis. Multichannel plots are
overlay plots with the highest number channel displayed as the top most plot. Only channels enabled by
the Plot Enable control will report analysis error codes. Information about error codes can be accessed
through the Plot Error controls.
