is used to define the lowest frequency at which a
calibration kit standard can be used during measurement
calibration. In waveguide, this must be the lower cutoff
frequency of the standard, so that the analyzer can
calculate dispersive effects correctly (see

the trace for a particular value or bandwidth.
calculates and displays the mean, standard deviation, and
peak-to-peak values of the section of the displayed trace
between the active marker and the delta reference marker.
If there is no delta reference, the statistics are calculated
for the entire trace. A convenient use of this feature is to
find the peak-to-peak value of passband ripple without
searching separately for the maximum and minimum
values.
The statistics are absolute values: the delta marker here
serves to define the span. For polar and Smith chart
formats the statistics are calculated using the first value
of the complex pair (magnitude, real part, resistance, or
conductance).
