Calculate the Statistics of the Measurement Data
This function calculates the mean, standard deviation, and peak-to-peak values of the section
of the displayed trace between the active marker and the delta reference. If there is no delta
reference, the analyzer calculates the statistics for the entire trace.

deviation, and peak-to-peak values of the section of the measurement data between the
active marker and the delta reference marker.
An application for this feature is to
fmd
the peak-to-peak value of
passband
ripple without
searching separately for the maximum and minimum values.
If you are viewing a measurement in the polar or Smith Chart format, the analyzer
calculates the statistics using the
first
value of the complex pair (magnitude, real part,
resistance, or conductance).
