Using the Optical Spectrum Analyzer
The Markers Menus
Next Pit Right
Places the marker on the next pit located at a longer wavelength than the current marker wavelength position. This next pit must meet the pit 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 right will begin from that point.
Active Marker....
Turns a particular marker ON or OFF. Turning a marker OFF will turn off any marker function that was on for that particular marker. When the marker is turned ON again, all the marker functions for that marker will be off.
Note
For addition information on setting the peak and pit excursion criteria, see “Peak Excursion ” and “Pit Excursion” on page

3Press the More Marker Functions.... softkey.
4Press the Noise Marker softkey.
5Toggle the noise marker ON or OFF.
The noise marker measures the spectral power density at the position of the active marker. The measurement is referenced to a 0.1 nm or 1 nm resolution bandwidth. The reference bandwidth used to normalize the noise is selected on the Marker setup panel. See “To change the default marker settings” on page
