Using the Optical Spectrum Analyzer
The Markers Menus
Use Marker Search Threshold
This limits the marker search function to data points above the selected threshold level.
Marker Search Threshold Value
Selects the amplitude threshold value used for limiting the marker search function. When Marker Search Threshold is ON, a dotted line is shown on the display at the threshold level.
Noise Marker Reference Bandwidth
Sets the normalization bandwidth for the noise marker. There are two allowable settings: 1 nm and 0.1 nm.
Note
Changing this value will change the value of the noise marker by 10 dB.
Peak Search at End of Each Sweep
Finds the peak value of the trace and moves the marker to the peak at the end of each sweep. This function operates on the active marker. This function operates on normal, delta, bandwidth and noise markers.
