Figure 84 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 85 on page -148 illustrates how these modes work for a three-cycle
wavelength sweep.
