• Average value.
• Root-mean-square (RMS) value.

Note
• If you wish to view the statistical calculations on data at different cursor positions, reposition
the cursors. If you proceed in this way it is not necessary to close the Statistics window.
• The Statistics window displays the statistics of the group in the active window, regardless if
a waveform is displayed or not.
• The size of the Statistics window can’t be altered. Use the scrawl bar to view other channel
results.
• If no cursors are being used, statistics from the first to last channel will be displayed.
