Product-Specific Commands—Description
DEFault allows the instrument to select a value
for the <Center> parameter.
The <Center> parameter corresponds to a valid
channel center wavelength in meter.
The
CALCulate[1..n][:WDM]:CHANnel:CENTer[:WAV
elength]? MIN and
CALCulate[1..n][:WDM]:CHANnel:CENTer[:WAV
elength]? MAX queries can be used to determine
valid channel center wavelength range.
Example(s) CALC:WDM:CHAN:DEF "CWDM_7",1450.0 NM
CALC:WDM:CHAN:SEL "CWDM_7"
CALC:WDM:CHAN:CENT:WAV? Returns
1.45000E-006
CALC:WDM:CHAN:CENT:WAV 1445.0 NM
CALC:WDM:CHAN:CENT:WAV? Returns
1.44500E-006
