Product-Specific Commands—Description
DEFault allows the instrument to select a value
for the parameter.
The parameter corresponds to a
valid distance in hertz from peak to center of
noise region.
The
CALCulate[1..n][:WDM]:CHANnel:NOISe:DISTan
ce:FREQuency? MIN and
CALCulate[1..n][:WDM]:CHANnel:NOISe:DISTan
ce:FREQuency? MAX queries can be used to
determine valid distance values.
Example(s) CALC:WDM:CHAN:DEF "C_23",195.0 THZ
CALC:WDM:CHAN:SEL "C_23"
CALC:WDM:CHAN:NOIS:TYPE POLY5
CALC:WDM:CHAN:NOIS:DIST:FREQ 125.0 GHZ
CALC:WDM:CHAN:NOIS:DIST:FREQ? Returns
1.250000E+011
Notes Custom noise measurement distance is applied
only if selected noise type is POLYnomial5.
