ANALYSIS
For the AQ6373/AQ6373B, replace “WDM” with “OSNR(WDM)” for all commands that
start with “WDM.”
Example)WDMANALYSIS→OSNR(WDM)ANALYSIS
The following commands are not available.
All commands that start with “EDFA-NF”
The following commands are not available on the AQ6375 if the wavenumber markers
are set.
• All commands that start with “WDM”
• All commands that start with “EDFA-NF”
• All commands that start with “FILTER”
Program Command Description Instrument models on which the
command is valid, parameter
ranges, and supported variables.
