Performing a Sweep Sequence
Performing a Sweep Sequence
The
SWEEP
mode enables you to make the laser perform a continuous sweep over a
defined wavelength or frequency range: starting from the start wavelength, the laser
continuously sweep until it has reached the stop wavelength, according to the parameters
(speed, pause, cycles) you have set.
You can start the sweep manually or with a trigger signal.
Configuring the Continuous Sweep
The Sweep mode settings menu enables you to define all parameters requested for the
sweep sequence.
