Absolute mode: the frequency or the wavelength
of the selected channel in [THz] or in [nm]
Relative mode: the frequency or wavelength
difference to the reference channel
Grid: Offset shows deviation from Grid wave-
length in [GHz] or in [nm]
Permanent: Spacing shows spacing between the
channels in [THz] or in [nm]
Absolute mode: the level of the channel in [dBm[
Relative mode: the difference level to the refer-
ence channel in dB
