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:AUTO:NOISe:
DISTance[:WAVelength]? MIN and
CALCulate[1..n][:WDM]:CHANnel:AUTO:NOISe:
DISTance[:WAVelength]? MAX queries can be
used to determine valid distance values.
Example(s) CALC:WDM:CHAN:AUTO:NOIS:TYPE POLY5
CALC:WDM:CHAN:AUTO:NOIS:DIST:WAV 40.0
NM
CALC:WDM:CHAN:AUTO:NOIS:DIST:WAV?
Returns 4.000000E-008
Notes Custom noise measurement distance is applied
only if selected noise type is POLYnomial5.
