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.
