³ Channel name: indicates the name of the channel as defined in the
channel list.
³ Center wavelength/frequency: indicates the spectral center-of-mass
for the peak in that channel.
³ Wavelength/Frequency deviation: indicates the difference between
the channel center wavelength/frequency and the measured signal
center wavelength/frequency.
³ Signal power: indicates the signal power for the selected channel
(excludes noise).
³ OSNR: is the Optical Signal to Noise Ratio, given by Signal power
(according to the current calculation method, in dBm) minus Noise
(according to the current calculation method, in dBm).
³ Noise: indicates the level of the noise for the selected channel.
