[:SOURce<hw>]:AWGN:BWIDth:RATio <Ratio>
In Additive Noise and Noise Only (SOUR:AWGN:MODE ADD|ONLY) modes, sets the
ratio of minimum real noise bandwidth to system bandwidth.
The overall bandwidth is calculated as follows and may not exceed the total bandwidth
specified in the data sheet:
Overall Bandwidth = System BW x Min Noise/System BW Ratio
Parameters:
<Ratio>
Example:
Manual operation:
[:SOURce<hw>]:AWGN:CNRatio <CnRatio>
In Additive Noise and CW Interferer (SOUR:AWGN:MODE ADD|CW) mode, sets the car-
rier/interferer ratio. The value range depends on the selected AWGN mode.
Parameters:
<CnRatio>
Example:
Manual operation:
[:SOURce<hw>]:AWGN:DISP:MODE <Mode>
Selects the display mode to Bseband or RF.
Parameters:
<Mode>
