Using the Optical Spectrum Analyzer

The Markers Menus

To set the delta marker function

1Place the marker to be used as a reference on the desired trace and at the desired wavelength.

2Press the front-panel Markers key.

3Press the More Marker Functions.... softkey.

4Press the Delta Marker softkey.

To fix the position of the reference marker and activate the delta marker, tog- gle the delta marker ON. Use the front-panel knob or keypad to move the delta marker to the desired location. If the delta function is turned ON and no marker is active, Marker #1 will be turned ON, placed at the center wavelength, and the delta function will be turned ON.

To calculate the total power under a trace

1Press the front-panel Markers key.

2Press the More Marker Functions.... softkey.

3Use the Trace Integ softkey to turn trace integration on.

Only one total power calculation can be turned on at a time. For example, if a total power calculation is being performed on trace A, turning a total power calculation for trace B ON will turn the calculation for trace A OFF.

To set the wavelength line markers

1Press the front-panel Markers key.

2Press the More Marker Functions.... softkey.

3Press the Line Marker Menu.... softkey.

4Press the Wavelength Marker 1 or Wavelength Marker 2 softkey.

5Position the line markers using the knob, step keys, or numeric entry pad.

Line markers let you perform sweeps, searches and integrations over a reduced section of the selected wavelength range. Wavelength Marker 1 is always to the left of Wavelength Marker 2.
