Setting the Emission Wavelength/Frequency
Tunable Laser Source
35
Performing a Sweep Sequence
When it receives a rising edge, the laser starts sweeping from the start
wavelength/frequency according to the parameters you have defined in the Sweep
mode settings menu.
Then the behavior depends on the selected parameters: when the laser reaches the
stop wavelength/frequency, it pauses during the time set in the
Pause parameter,
moves back to the start position and waits for the next trigger to start the following
sweep.
When it has completed the number of cycles, the sweep stops and if the
Auto-Return
parameter is selected, the laser moves to the start position.
To stop the sweep sequence:
³
To stop the sweep sequence in progress or to disarm the laser, touch the button.
The laser stops the sequence and stays at the current wavelength/frequency position.
Triggers are not taken into account anymore.
If the
Auto-Return parameter is selected, the laser does not move to the start position.
