Computes the power spectral density in the specified bandwidth and writes the results in Trace F. The target trace is a single trace selected from Traces A to E. You can set the bandwidth in the range from 0.1 nm to 10 nm in 0.1 nm steps. The trace display at the side of the data area shows "PWR/NBW @". Marker Functions > Marker functions can be used to easily measure wavelength differences and level differences, and to search for peak wavelengths, peak levels, and spectrum widths. There are markers, line markers, and advanced markers. Markers A total of 1025 markers (one moving marker and 1024 fixed markers) are provided. Moving markers can be moved to an arbitrary wavelength using the rotary knob, arrow keys, or numeric key pad. You can also drag the markers with the mouse. Moving markers can be moved over a waveform to display the marker values (wavelength and level value) in the data area. If a moving marker is fixed in an arbitrary position, it changes to a fixed marker. Fixed markers are markers fixed to a number on which the moving marker was set. Fixed markers are assigned marker numbers in order starting from 001. You can enter an arbitrary number using the rotary knob, arrow keys, or numeric key pad. A number up to 1024 can be set. When multiple fixed markers are set, it is possible to display wavelength differences and level differences between a given marker and adjacent markers.
