:NOISe:POWer:CONTrol[:MODE]
Supported N5172B/82B with Option 403
[:SOURce]:RADio:MTONe:ARB:NOISe:POWer:CONTrol[:MODE] TOTal|CARRier|NOISe
[:SOURce]:RADio:MTONe:ARB:NOISe:POWer:CONTrol[:MODE]?
This command sets the power control to one of the three following modes:
Total This is the default mode where the total power and C/N are independent variables
and the carrier power and total noise power are dependent variables set by the
total power, C/N and the rest of the noise settings. The carrier power and total
noise power will change as any noise parameter is adjusted to keep the total
power and the C/N at their last specified values.
Carrier In this mode the carrier power and C/N are independent variables and the total
power and total noise power are dependent variables set by the carrier power,
C/N and the rest of the noise settings. The total power and total noise power will
change as any noise parameter is adjusted to keep the carrier power and the C/N
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.

:NOISe:POWer:NOISe:CHANnel?
Supported N5172B/82B with Option 403
[:SOURce]:RADio:MTONe:ARB:NOISe:POWer:NOISe:CHANnel?
The query returns the current noise power across the carrier bandwidth in dBm.
:NOISe:POWer:NOISe:TOTal
Supported N5172B/82B with Option 403
[:SOURce]:RADio:MTONe:ARB:NOISe:POWer:NOISe:TOTal <totalNoisePowerInDbm>
[:SOURce]:RADio:MTONe:ARB: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.
