:NOISe:MUX

[:SOURce]:RADio[1]:MTONe:ARB:NOISe:MUX SUM|CARRier|NOISe
[:SOURce]:RADio[1]:MTONe:ARB:NOISe:MUX?
This command enables diagnostic control of additive noise, such that only the noise, only the carrier,
or the sum of both the noise and the carrier are output from the internal baseband generator. With
the ALC off, this feature enables direct measurement of just the carrier or the noise contributions to
the total power. The system will still behave as if both the noise and the carrier are present on the
output when it comes to determining the Auto Modulation Attenuation and the RMS level for RMS
Power Search.
Example
:RAD:MTON:ARB:NOIS:MUX CARR
The preceding example enables the direct measurement of the carrier contribution to the total power.

:NOISe:POWer:CARRier
Supported N5172B/82B with Option 403
[:SOURce]:RADio:MTONe:ARB:NOISe:POWer:CARRier <carrierPower>
[:SOURce]:RADio:MTONe:ARB:NOISe:POWer:CARRier?
This command sets the current carrier power level if noise is on.
In the CARRier control mode, the total power will be adjusted to achieve the specified carrier power
and the carrier power level will be maintained regardless of changes to the other noise parameters. A
change to the total power will change the carrier power setting appropriately to maintain the C/N
ratio.
In the TOTal control mode, this will adjust the total power once for the specified carrier power level,
after which the carrier power could change if any noise parameters are adjusted or the total power
is adjusted.
In the NOISe control mode, this will adjust the total noise power once for the specified carrier power
level, after which the carrier power could change if any noise parameters are adjusted or the total
noise power is adjusted. See also :NOISe:POWer:CONTrol[:MODE] and :NOISe:POWer:NOISe:TOTal
commands.
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).
