The Counter is now set to make statistics based on 20 measurements.
In this case, the displayed standard deviation value is computed on all measurements
of the 10 MHz signal since no limits were set.
Computing Stats on Filtered Data Only
A special feature of the Counter allows you to use the upper and lower limits to filter
data before statistical processing or computation as shown in Figure 1-4.
