Product-Specific Commands—Description
DEFault allows the instrument to select a value
for the <Distance> parameter.
The <Distance> parameter corresponds to a
valid distance in hertz from peak to center of
noise region.
The
CALCulate[1..n][:WDM]:CHANnel:AUTO:NOISe:
DISTance:FREQuency? MIN and
CALCulate[1..n][:WDM]:CHANnel:AUTO:NOISe:
DISTance:FREQuency? 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:FREQ 100.0
GHZ
CALC:WDM:CHAN:AUTO:NOIS:DIST:FREQ?
Returns 1.000000E+011
Notes Custom noise measurement distance is applied
only if selected noise type is POLYnomial5.
