channel width in meter.
The
CALCulate[1..n][:WDM]:CHANnel:AUTO:WIDTh[
:WAVelength]? MIN and
CALCulate[1..n][:WDM]:CHANnel:AUTO:WIDTh[
:WAVelength]? MAX queries can be used to
determine valid channel wavelength width.
Example(s) CALC:WDM:CHAN:AUTO:WIDT:WAV 12.5 NM
CALC:WDM:CHAN:AUTO:WIDT:WAV? Returns
1.250000E-008
