Source
Real-Time AWGN
Allows you to enable or disable adding real-time AWGN to the carrier modulated by the waveform
currently being played by the dual ARB.

Remote Command
:SOURce:RADio:ARB:NOISe[:STATe] ON|OFF|1|0
:SOURce:RADio:ARB:NOISe[:STATe]?
Example
:SOUR:RAD:ARB:NOIS OFF
Dependencies
When a new waveform is selected for playback the settings contained within the associated
waveform header file are applied to the ARB. The AWGN state is one of the values stored within the
header file. If the newly selected waveform file has an associated header file, the AWGN state is
updated with the value from the header file. The AWGN state will remain unchanged if the newly
selected waveform does not have an associated header file.
Couplings
If this setting is On and
ARB State is On,
RF Power will
be adjusted to the value to maintain the AWGN power relationship defined by
Power Control Mode and other noise settings
Preset

Carrier To Noise Ratio
Allows you to specify the carrier to noise ratio (C/N) in dB. The carrier power is defined as the total
modulated signal power without noise power added. The noise power is applied over the specified
bandwidth of the carrier signal.

Remote Command
:SOURce:RADio:ARB:NOISe:CN <ampl>
:SOURce:RADio:ARB:NOISe:CN?
Example
:SOUR:RAD:ARB:NOIS:CN 0.00 dB
Dependencies
When a new waveform is selected for playback the settings contained within the associated
waveform header file are applied to the ARB. The AWGN C/N ratio is one of the values stored within
the header file. If the newly selected waveform file has an associated header file, the AWGN C/N
ratio is updated with the value from the header file. The AWGN C/N ratio will remain unchanged if
the newly selected waveform does not have an associated header file.
