16A continuous sweep can end in two ways:
a when the sweep is completed, or
b when you press [Stop].
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.
4 Perform step 4 to step 13 on page 137 to set the sweep parameters.
5 Press the [Active] hardkey on the front panel of your Tunable Laser module to
enable the optical output.
How to Perform a Wavelength Sweep
start wavelength must be smaller than stop wavelength
the total time of the sweep is too small
the total time of the sweep is too large
the trigger frequency (calculated from sweep speed divided by
sweep step) is too large
step size too small
the number of triggers exceeds the allowed limit
The only allowed modulation source with the lambda logging
function is coherence control.
lambda logging only works "Step Finished" output trigger
configuration
lambda logging can only be done in continuous sweep mode
the step size must be a multiple of the smallest possible step size
