Product-Specific Commands—Description
DEFault allows the instrument to select a value
for the <Width> parameter.
The <Width> parameter corresponds to a valid
width in hertz for the noise measurement region.
The
CALCulate[1..n][:WDM]:CHANnel:NOISe:WIDTh
:FREQuency? MIN and
CALCulate[1..n][:WDM]:CHANnel:NOISe:WIDTh
:FREQuency? MAX queries can be used to
determine valid width values.
Example(s) CALC:WDM:CHAN:DEF "ITU_22",192.1750 THZ
CALC:WDM:CHAN:SEL "ITU_22"
CALC:WDM:CHAN:NOIS:TYPE POLY5
CALC:WDM:CHAN:NOIS:WIDTh:FREQ 75.0 GHZ
CALC:WDM:CHAN:NOIS:WIDTh:FREQ? Returns
7.500000E+010
Notes Custom width for noise measurement region is
applied only if selected noise type is
POLYnomial5.
