Using the Instrument
Analyzer Operating Modes
The light is output from the optical spectrum analyzer's front panel monochro-
mator output connector. This light is a filtered (by the resolution bandwidth)
and attenuated (by the monochromator loss) light input to the front panel
monochromator input connector.
5 Press Marker Tune (Applications > Measurement Modes > Filter Mode >
Marker Tune). Turn the front panel knob to tune the preselector to any
displayed wavelength.
6 If 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.
7 Press 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 µ m
monochromator output connector into a 9 µ m fiber optic cable.
1 Connect the light source to the optical spectrum analyzer's front panel
monochromator input connector. Use a 9 µ m fiber optic cable.
2 Connect a 9 µ m fiber optic cable between the front panel monochromator
output and photodetector input connectors.
3 Press 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 screen.
4 Press Applications > Measurement Modes >
