How to Set the Wavelength Sweep

The Sweep Parameters
These are the parameters for the wavelength sweep:
• [λ Start], the wavelength at which the sweep begins,
• [λ Stop], the wavelength at which the sweep ends,
• [Step], the size of the change in the wavelength for each step of a stepped
sweep,
• [Cycles], the number of times the sweep is repeated,
• [Dwell], the amount of time spent at the wavelength during each step, for a
stepped sweep
• [Vsweep], the speed of a continuous sweep,
• [Sweep mode], see "How to Perform a Sweep" on page 137,
• [Repeat mode], see "How to Set the Repeat Mode" on page 135.
For a <Continuous> sweep, [Step] sets the wavelength interval between
output triggers, if you have set <Output Trigger Mode> to <Step Finished>,
see "How to Use Output Triggering" on page 152.

How to Set the Repeat Mode
The [Repeat Mode] determines how the instrument performs a multi-cycle
sweep.
• Select <Twoway>, if you want to start every odd sweep cycle at [λ Start] and to
start each even sweep cycle at [λ Stop].
