³ Start range (nm or THz): indicates the starting range of the

channel list.

³ Stop range (nm or Thz): indicates the ending range of the

channel list.

³ Channel center wavelength/frequency: indicates the 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.

³ Channel distance (nm or GHz): indicates distance between the

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.

³ Channel width (nm or GHz): indicates the limit inside which the

power values will be considered in the channel. Integrated power

is calculated on channel width.

³ Name prefix: Adds prefix to the channel names.
