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.
