SCPI Command Reference
430 FTB-5240S/S-P/BP
Product-Specific Commands—Description
DEFault allows the instrument to select a value
for the parameter.
The parameter corresponds to a
valid distance in meter from peak to center of
noise region.
The
CALCulate[1..n][:WDM]:CHANnel:NOISe:DISTan
ce[:WAVelength]? MIN and
CALCulate[1..n][:WDM]:CHANnel:NOISe:DISTan
ce[:WAVelength]? MAX queries can be used to
determine valid distance values.
Example(s) CALC:WDM:CHAN:DEF "CWDM_3",1410.0 NM
CALC:WDM:CHAN:SEL "CWDM_3"
CALC:WDM:CHAN:NOIS:TYPE POLY5
CALC:WDM:CHAN:NOIS:DIST:WAV 40.0 NM
CALC:WDM:CHAN:NOIS:DIST:WAV? Returns
4.000000E-008
Notes Custom noise measurement distance is applied
only if selected noise type is POLYnomial5.
