Automatic Peak Markers
Automatic peak markers are on by default and assist with quickly identifying the frequency and amplitude of peaks in
the spectrum.
1. The Reference Marker is placed on the
highest amplitude peak. It is marked with
a red R in a triangle.
2. The automatic markers indicate
frequency a
nd amplitude.
3. Absolute re
adouts show the actual
frequency and amplitude of the
automatic markers.
4. Delta readouts s how the frequency and
amplitude
of the automatic markers
relative to the reference marker.
In the screen shot shown below, a marker has been placed on each of the obvious peaks in the display. The Reference
Marker is the highest peak. It i s marked with the red R in a triangle, and its readout is shown in red text.

Use Threshold and Excursion to define which peaks are marked.
The threshold is a minimum amplitude that a signal must cross to be a valid peak. If the threshold is lower, more peaks will
tend to qualify to have markers. If the threshold is higher, fewer peaks tend to qualify to have markers.
The excursion is how far a signal needs to fall in amplitude between marked peaks to be another valid peak. If the excursion
is low, more peaks will tend to qualify to have a ssociated markers . If the excursion is high, fewer peaks will tend to qualify to
have associated markers.
