8.5.8.4 Valley Track

Through the Valley Track analysis tool it is possible to track the position, depth, and width of
valleys in the spectrum over time. The maximum number of valleys that can be simultaneously
tracked is 2048.
When the Valley Track tool is active, the
played below the main data display area. Here, a data table shows information about the val-
leys, as well as a small toolbox with the settings that were used to find the valleys. It is also
possible to select which columns are displayed in the data table by clicking on "Select
Columns" button.
The criteria used to find the valleys are:
· Threshold: Only valleys where the local baseline has an intensity above the threshold will
be found by the search.
· Range: Limits the x-axis range over which the search for valleys is performed.
· Maximum number of valleys (found in the Settings dialog box behind the cogwheel icon):
Limits the number of valleys returned by the valley track analysis. The default value is 200
valleys; the maximum value is 2048 valleys.
· Min valley depth (dB) (found in the Settings dialog box behind the cogwheel icon): Only
valleys which have a depth of at least this value (defined by the local baseline) will be
found.
These settings also are corresponding to the "Peak Track" tab in the Basic settings dialog for
selecting default preferences, see section
When the Valley track tool is active, the Active spectrum trace is checked for valleys upon the
collection of a new spectrum from the instrument. By default, the valleys are sorted in order of
increasing x-axis location. Right-clicking in the data table brings up a contextual menu from
