Query onlyUsage:
[:SOURce<hw>]:AWGN:STATe <State>
This command activates or deactivates the white noise (AWGN = Averaged White Gaus-
sian Noise). The noise signal is either superimposed on the baseband signal ("Additive
Noise" mode (SOUR:AWGN:MODE ADD)) or is output as a pure noise signal ("Noise
Only" mode (SOUR:AWGN:MODE ONLY)). In addition, a sine with adjustable frequency
offset to the baseband signal can be generated as an RFI signal ("CW Interferer" mode;
SOUR:AWGN:MODE CW).

7.15.3 SOURce:BB Subsystem
This subsystem contains all commands for digital signal generation. It is divided into
several subsystems which are described separately.
OUTPut<ch>
The numeric suffix to OUTPut distinguishes between the available markers.
EXTernal<ch>
The numeric suffix to EXTernal distinguishes between the available external trigger
inputs.
