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:AUTO:NOISe:
WIDTh:FREQuency? MIN and
CALCulate[1..n][:WDM]:CHANnel:AUTO:NOISe:
WIDTh:FREQuency? MAX queries can be used
to determine valid width values.
Example(s) CALC:WDM:CHAN:AUTO:NOIS:TYPE POLY5
CALC:WDM:CHAN:AUTO:NOIS:WIDTh:FREQ
100.0 GHZ
CALC:WDM:CHAN:AUTO:NOIS:WIDTh:FREQ?
Returns 1.000000E+011
Notes Custom width for noise measurement region is
applied only if selected noise type is
POLYnomial5.
