How to Perform a Manual Sweep
You can perform a manual sweep if you choose the < Manual > sweep mode
or if you press [Pause] during an automatic sweep. In a manual sweep you
choose when you want to perform each step of a stepped sweep. You can
choose to move forward or backward a wavelength or to end the sweep.
To perform a manual wavelength sweep over the range 1510 nm to
1570 nm, three times, sweeping two ways, in 1 nm steps:
1 Move to the Tunable Laser channel and press [Details].
2 Move to [
Sweep Mode ] and press Enter.
3 Move to the < Manual >, by using the cursor key, and press Enter .
