Note
If coherence control is enabled, and the uncal power level
cannot be exceeded for the full wavelength range chosen, the
wavelength range is reduced as necessary.

Example
Set the instrument to sweep the range 1495nm to 1555nm,
three times, in 1nm steps, stopping for half a second at
each wavelength, at the highest power level available at all
wavelengths.
