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. Press Sweep. You will be in the START 
 menu.
2. Press ENTER. The Edit marker starts blinking in the lower part of the
display.
3. Turn the selection dial clockwise or counterclockwise until the desired
wavelength is displayed.
4. Press ENTER. You can select a wavelength at a resolution of 0.001 nm.
5. To exit the Sweep menu, press Sweep.
OR
Turn the dial clockwise or counterclockwise until EXIT is displayed,
then press ENTER.
