between input and output.
Sets the start wavelength for the scan.
Sets the stop wavelength for the scan.
Sets the peak excursion value. This is the amount of
amplitude that trace must raise and fall to be
considered as a peak. Lower values lead to more
signals being discerned, but if the peak excursion is set
too low, peaks in the noise floor may be discerned as
signals.
Sets the peak threshold value. Power levels below this
threshold are not considered for peak search.
Selects the offset value to measure the noise floor. This
value is used in the OSNR calculation.
