The COSA-4055 modules provide a Drift measurement application to
perform multiple measurements and display the recorded results in a
graphical format (trace) over the time.
This can be used to monitor the drift of power and wavelength of optical
systems or components. This is important to measure the drift of non
temperature stabilized transmitter in CWDM networks.
NOTE
A Drift measurement can only be done at predefined wavelengths or
frequencies, for this reason a reference Grid needs to be defined and
the Channel Detection parameter is set to Grid.
