Adjusting Your Unit According to Wavelength
Adjusting Your Unit According to Wavelength
It is possible to introduce an offset in your Tunable Laser Source to correct
a wavelength deviation as measured by a reference wavelength meter.
Note: A calibrated wavelength meter is required to perform a user calibration on
your unit.
To adjust your module at a certain wavelength:
1. Turn your Tunable Laser Source on.
2. Set your Tunable Laser Source at the desired wavelength as explained
in Selecting a Wavelength on page 20.
3. Select the Settings function tab.
4. Click the User Calibration tab.
5. Connect your IQS-2600B to a calibrated wavelength meter and enter
the measured wavelength in the corresponding box.
6. Click Adjust. Your unit will verify if there is a difference between the
value you have entered and its current wavelength position. If there is a
difference, it will add an offset to compensate.
This user-performed calibration feature can help you achieve better
absolute wavelength accuracy if, for example, you feel that conditions
outside the unit may have affected the calibration.
