Threshold
Sets an absolute threshold as an additional condition for the peak search. Only peaks
that exceed the threshold are detected.
This setting is only available for spectrum waveforms. It is valid for cursor measure-
ments, spectrum measurements and peak search.

Peak excursion
Defines a minimum level value by which the waveform must drop left and right of the
local maximum to be listed as a peak. Enter a peak excursion value to omit close by
peaks and list just the highest peak.
This setting is only available for spectrum waveforms. It is valid for cursor measure-
ments, spectrum measurements and peak search.
Example:
In the figure below, 2 peaks are shown, that rise above the defined "Threshold". Peak 1
fulfills the defined "Peak excursion" value and is counted as a peak. Peak 2 does not
fulfill the defined "Peak excursion" value on the right and is not counted as a peak.
