Using the Multi-Wavelength Meter
Displaying Wavelength and Power
Peak WL mode
When Peak WL is pressed, the display shows the largest amplitude line in the spec-
trum. This is the peak wavelength mode. The word PEAK is shown on the screen. If
multiple laser lines are present at the input, the number of lines located will be
shown along the right side of the screen.
Display after "Peak WL" key pressed
In addition to the digital readouts, there is a power bar. It provides a convenient ana-
log "meter movement" for tuning laser power.
Although the Peak WL mode shows one signal at a time, softkeys are provided that
allow you to scroll through and display all the measured laser lines. You can scroll
through the list according to the wavelengths or powers measured. The signals are
displayed in order from shortest to longest wavelengths. The Agilent 86120B can
measure up to 100 laser lines simultaneously.
To display peak wavelength and power
1 Connect the fiber-optic cable to the front-panel OPTICAL INPUT connector.
