Note that when you apply one of the notch filters, measurement results for these
frequency ranges are not displayed. The result is a gap in the trace in these ranges
where markers do not work.
On both sides of the filter, an additional "Exclusion Band" is added. The width of
the exclusion band is 1
% of the lower and upper bandwidth of the notch filter (thus
it has a different width on both sides of the filter). The edges of the exclusion band
are indicated by two vertical lines in the diagram.
An orange arrow in the diagram represents the path you have selected.
For more information, see Chapter 10.7.1.3, "Using the Preselector" , on page 172.
