If you increase the span around a center wavelength beyond one of the end
wavelength limits, the center wavelength will change to a value that will allow
the span to increase. For example, if the center wavelength is set to 1680 nm
and you increase the span to 100 nm, the center wavelength changes to 1650
nm in order to be able to accommodate the 100 nm span.

Start WL
Sets the start wavelength. The center wavelength and span are adjusted so
that:

Use the knob, step keys, or numeric keys to enter the desired value.
If the instrument is in zero span, this command sets the center wavelength to
the value specified.
The default setting for start wavelength is 600 nm.
