Amp-P
This driver sets parameters for optical AMP measurement.
Input parameters:
Parameter [cluster]...................... Set the following cluster elements.
(When no value is input, the previous setting is used.)
1. NF Select (no change) .......... Select an NF calculation mode between NF (S-ASE) and NF (Total).
2. Method (no change) ............. Select an NF measurement method.
1: NF measurement made without using a spectrum division method
2: NF measurement made using a spectrum division method
3: NF measurement using a polarization nullification method
4: NF measurement made using a pulse method
5: WDM measurement
3. ASE Fitting (no change)....... Select a fitting method used for obtaining an ASE level.
1: Gauss fitting
2: Mean
4. Fitting Span (nm) (no change) .. Set a span subject to the fitting carried out to obtain an ASE level.
5. Masked Span (nm) (no change)
.............................................. Set a span excluded from the fitting carried out to obtain an ASE level.
6. Pin Loss (dB) (no change).... Set the difference between the level of the signal light input to the optical ampli-
fier and the level of the signal light input to the optical spectrum analyzer.
7. .............................................. Set the difference between the actual level of the optical amplifier output signal
and the level of the optical amplifier output signal input to the optical spectrum
analyzer.
8. NF Cal (no change) .............. Set a calibration value used for NF calculation.
9. O.BPF Lvl Cal (dB) (no change)
.............................................. Set the difference in level between the pass and block ranges of the optical band
pass filter inserted between the optical amplifier and the optical spectrum ana-
lyzer.
10. O.BPF BW (nm) (no change) .. Set an effective optical filter width used for NF (total) calculation.
11. Pol Loss (dB) (no change).... Set a level loss at the polarization control nullifying stage used for polarization
nullification.
