Noise:cnformat; Noise:ebno - Agilent Technologies N5171B Command Reference Manual

This command sets the carrier to noise ratio 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. For more information, refer to :NOISe:CBWidth.
Example
:RAD:ARB:NOIS:CN 50DB
The preceding example sets the carrier to noise ratio to 50 dB.
