• Value of λ fwhm
λ fwhm indicates the center wavelength obtained through the RMS analysis (k =
2.35).
The unit is always nm. A value is output down to the third decimal place.
When analysis is impossible, –1 is output.
• Value of λ ndb
λ ndb indicates the center wavelength obtained through the threshold analysis
(ndB).
The unit is always nm. A value is output down to the third decimal place.
When analysis is impossible, –1 is output.
• Value of FWHM
FWHM indicates the half-magnitude full width obtained through the RMS analy-
sis (k = 2.35)
The unit is always nm. A value is output down to the third decimal place.
When analysis is impossible, –1 is output.
• Value of BWndb
BWndb indicates the wave width obtained through the threshold analysis (ndB).
The unit is always nm. A value is output down to the third decimal place.
When analysis is impossible, –1 is output.
• Value of λ p
λ p indicates a peak wavelength.
The unit is always nm. A value is output down to the third decimal place.
When analysis is impossible, –1 is output.
• Value of Lp
Lp indicates a peak level.
The unit is dBm. A value is output down to the second decimal place.
When analysis is impossible, –999.99 is output.
• Value of PKdens
PKdens indicates a peak power per mm.
The unit is always dBm. A value is output down to the second decimal place.
When analysis is impossible, –999.99 is output.
• Value of POW
POW indicates a power integration value.
The unit is always dBm. A value is output down to the second decimal place.
When analysis is impossible, –999.99 is output.
