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 114
•
[
Repeat mode
], see
“How to Set the Repeat Mode” on page 113
.

.
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
].
