Marker Functions - Agilent Technologies 86038B User Manual

Excursion Sets the peak or pit excursion value for the marker
search functions. It is used to determine which spectral features
are classified as peaks or pits. To be classified , each trace peak
or pit must rise, and then fall by at least the excursion value.
Setting the value too high will result in failure to include the
smaller responses. Setting the value too low will cause all
spectral features to be chosen.

Marker Search Shortcut accesses the Marker Search panel.
