Analyzer Operating Modes
The light is output from the optical spectrum anal yzer ’s front panel monochro-
mator output connector. This light is a filtered (by the res o lution bandwidth)
and attenuated (by the monochromator loss) light input to the front panel
monochromator input connector.
5Press Marker Tune (Applications > Measurement Modes > Filter Mode >
Marker Tune). Turn the front panel knob to tu ne the preselector to any
displayed wavelength.
6If the input light changes, or if you change the span of the optical spectrum
analyzer, press Take Sweep to update the displayed trace with valid waveform
data.
7Press Previous Menu to return to normal optical spectrum analyzer
operation.
To use a single mode output cable
This procedure ensures the best launching of the output light from the 50 µm
monochromator output connector into a 9 µm fiber optic cable.
1Connect the light source to the optical spectrum analyzer’s front panel
monochromator input connector. Use a 9 µm fiber optic cable.
2Connect a 9 µm fiber optic cable between the front panel monochromator
output and photodetector input connectors.
3Press Auto Meas. After the routine has ended, check that the display shows the
wavelength range of interest. Adjust if necessary. The light response to be
preselected should be displayed on the scr een.
