Peak list and markers
You can define various criteria for a peak search. The peaks are indicated in the fre-
quency diagram by markers, and the measured peak frequencies and magnitudes are
listed in the peak list. In addition, you can define a reference marker and get the peak
results as delta values to the values of the reference marker.
► To save the results, or to open the "Marker" menu directly, use the icons on the
right side of the peak list.
