Tunable Laser Source 29
5 Setting Sweep Parameters
Your Tunable Laser Source allows you to perform automatic wavelength
scans according to user-defined parameters. You can perform a
continuous sweep (the source will make one or several continuous
passes), or you can perform a step-by-step sweep (the signal wavelength
changes according to preset increments or steps).
Setting the Start and End Wavelengths
The wavelength scans and their lengths (or duration) depend on the start
and end wavelengths you set.
To set the wavelengths for your scans:
1. Click the Settings function tab.
2. Select the Sweep tab.
3. Enter the desired values in the appropriate boxes.
Note: The start and end wavelengths of the sweep can be set in ascending or
descending order, with a minimum value of 1.0 nm. The sweep will be
performed accordingly.
