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.
