Figure 27 The Parameters for a Stepped Wavelength Sweep
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].
• Select Oneway, if you want to start every sweep cycle at [λ Start] and to
end every sweep cycle at [λ Stop].
Figure 28 illustrates how these modes work for a three-cycle wavelength
sweep.
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 71.
