[:SOURce<hw>]:AWGN:POWer:NOISe <Noise>
Available for modes Additive Noise, Noise Only and CW Interferer (SOUR:AWGN:MODE
ADD|ONLY|CW).
This command sets or queries the noise level in the system bandwidth depending on the
selected modes:
●
"Additive Noise" and "CW Interferer" mode (SOUR:AWGN:MODE ADD|CW)
- "Reference Mode Carrier" (SOUR:AWGN:POW:RMOD CARR)
The command queries the noise/interferer level which is derived from the entered
C/N value. The carrier level is set with command SOUR:AWGN:POW:CARRier.
- "Reference Mode Noise" (SOUR:AWGN:POW:RMOD NOIS
The command sets the noise/interferer level. The level of the carrier signal is
derived from the entered C/N value.
●
"Noise Only" mode
