Places the marker on the next highest peak from the current marker ampli- tude. This next highest peak must meet the peak excursion and threshold cri- teria. If the specified marker is OFF, it will be turned ON, placed at the center wavelength, and the search for the next maximum will begin from that point.
Next Peak Left
Places the marker on the next peak located at a shorter wavelength than the current marker wavelength position. This next peak must meet the peak excursion and threshold criteria. If the specified marker is OFF, it will be turned ON, placed at the center wavelength, and the search to the left will begin from that point.
