 Channel center wavelength/frequency: spectral center-of-mass for

the peak in that channel.

Note: When using the custom channel center wavelength option, the first channel

will be centered at the Start Range, and the list will be created using

channel distance and channel width.

 Channel distance (nm or GHz): distance between channels. The

value of channel distance will be set depending on the selection

made for the channel center wavelength option. The channel

distance box will be enabled only when the channel center

wavelength option is set to custom.

 Channel width (nm or GHz): limit inside which the power values

will be considered in the channel. Integrated power is calculated

on channel width.

 Name prefix: adds a prefix to the channel names.
