■ • Value of a [NF (S-ASE)/NF (Total)]
Select an NF calculation mode between NF (S-ASE) and NF (TOTAL).
a = 0: NF (S-ASE)
= 1: NF (Total)
• Value of b [Method]
Select an NF measurement method.
b = 0: NF measurement made without using a spectrum division method
= 1: NF measurement made using a spectrum division method
= 2: NF measurement made using a polarization nullification method.
= 3: NF measurement made using a pulse method
= 4: WDM measurement
• Value of c [Gauss/Mean]
Select a fitting method used for obtaining an ASE level (P ASE).
c = 0: Gauss fitting
= 1: Mean
• Value of d [Fitting span]
Specify a span, which represents the shortest and longest wavelengths subject to
the fitting carried out to obtain an ASE level (P ASE), with the signal light cen-
tered.
The unit is nm. Input a value down to the second decimal place.
Data range: 0.10 nm ≤ d ≤ 100.00 nm
• Value of e [Masked Span]
Specify a span, which represents the wavelength range (near the signal light)
where fitting is carried out to obtain an ASE level (P ASE), with the signal light
centered.
Fitting is carried out in the d-specified range excluding the e-specified range.
The unit is always nm. Input a value down to the second decimal place.
Data range: 0.10 nm ≤ d ≤ 100.00 nm
Note:
If the d- and e-specified wavelength area for fitting exceeds the measure-
ment range, the wavelength data in this area is excluded from fitting.
