Measuring Wavelength and Power

Peak WL mode

When Peak WL is pressed, the display shows the largest amplitude line in the spectrum. 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. In peak wavelength mode, the Agilent 86120C can measure up to 200 laser lines simultaneously.

In addition to the digital readouts, there is a power bar. It provides a convenient analog “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 wave- lengths or powers measured.

To display peak wavelength and power

1Connect the fiber- optic cable to the front- panel OPTICAL INPUT connector.

2To display the peak wavelength and power, do one of the following:

•Press the green Preset key.

•Press Peak WL.
