Peak value
TRACE B waveform
Measurement resolution used in the analysis algorithm (e.g. EDFA-NF)
If the RES BW parameter is set to
“MEASURED,” the resolution
bandwidth is determined from the
TRACE B waveform.
If the RES BW parameter is set to “CAL
DATA,” the resolution bandwidth stored
in the AQ6380 is used.

Resolution Calibration
Not executed or cleared
The analysis algorithm other than EDFA-NF uses the value stored in the AQ6380.
For details on the RES BW parameters, see appendix 5, “Parameters,” in
IM AQ6380-01EN.
3 dB
Clearing the Resolution Calibration Value
The calibration table of equivalent noise bandwidth is cleared. After clearing, the 3 dB width
resolution bandwidth is used in the analysis algorithm calculations.
Use this function when you need to align with existing analysis data.
