at their last specified values.
Total Noise In this mode the total noise power and C/N are independent variables and the
total power and carrier power are dependent variables set by the total noise
power, C/N and the rest of the noise settings. The total power and carrier power
will change as any noise parameter is adjusted to keep the total noise power and
the C/N at their last specified values.

The query returns the current noise power across the carrier bandwidth in dBm.
:NOISe:POWer:NOISe:TOTal
Supported N5172B/82B with Option 431 and 403
[:SOURce]:RADio:CUSTom:NOISe:POWer:NOISe:TOTal <totalNoisePowerInDbm>
[:SOURce]:RADio:CUSTom:NOISe:POWer:NOISe:TOTal?
This command sets the current total noise power level if noise is on.
In the NOISe control mode, the total power will be adjusted to achieve the specified total noise
power and the total noise power level will be maintained regardless of changes to the other noise
parameters. A change to the total power will change the total noise power setting appropriately to
maintain the C/N ratio.
In the TOTal control mode, this will adjust the total power once for the specified total noise power
level, after which the total noise power could change if any noise parameters are adjusted or the
total power is adjusted.
In the CARRier control mode, this will adjust the carrier power once for the specified total noise
power level, after which the total noise power could change if any noise parameters are adjusted or
the carrier power is adjusted. See also :NOISe:POWer:CONTrol[:MODE] command.
Range The range varies based on the bounds of the total power that results from the
noise settings.
Default The appropriate value given the current total power and the current Carrier to
Noise (C/N).
