How to Perform a Sweep?
There are three sweep modes:
• Stepped - which dwells at wavelengths that are separated by a certain
step size,
• Continuous - which sweeps continually at the speed you set, and
• Manual - which you can run each step manually.
You cannot turn the laser off by pressing the Active hardkey on the
Tunable Laser front panel, while a wavelength sweep is running.
You can press Stop Sweep and, then, press the Active hardkey on the
Tunable Laser front panel, to turn off the laser.
