Using the Multi-Wavelength Meter
Displaying Wavelength and Power
List by WL or power modes
In the list-by-wavelength or list-by-power modes, the measurements of five laser
lines can be displayed at any one time. In list by wavelength mode, the signals are
displayed in order from shortest to longest wavelengths. The Agilent 86120B can
measure up to 100 laser lines simultaneously. Use the
and softkeys to move
the cursor through the list of signals; the list can contain up to 100 entries. Press
the SELECT key, and the display changes to peak wavelength mode with the signal
at the cursor displayed.
Annotation in the upper right corner of the display indicates whether the signals are
ordered according to wavelength (
BY WL
) or power (
BY PWR
). The cursor shows
the currently selected laser line. As you scroll through the responses, the current
position of the selection cursor is shown along the screen’s right side.
Display after “List by WL” key pressed
Also notice that power bars graphically show the relative power levels between laser
lines.
To display multiple laser lines
1 Connect the fiber-optic cable to the front-panel OPTICAL INPUT connector.
2 Press the green Preset key.
3 Press List by WL to display the laser lines from the shortest wavelength to the longest
wavelength.
4 Press List by Power to display the laser lines in order of decreasing amplitudes.
