[:SOURce<hw>]:AWGN:DISP:ORESults <OResults>
(requires option R&S SGT-K18, Digital Baseband Connectivity)
In additive Noise and Noise Only (SOUR:AWGN:MODE ADD|ONLY) modes and for Dis-
play Mode set to Baseband (AWGN:DISP:MODE BB), selects the display of output
results for the analog (DACIF) or the digital (BBOUT) signal path.
Parameters:
<OResults>
Example:
[:SOURce<hw>]:AWGN:ENRatio <EnRatio>
In Additive Noise mode, sets the ratio of bit energy to noise power density.
For Digital Standard signals, the bit rate used for calculation of E
value is defined with command SOUR:AWGN:BRAT.
Parameters:
<EnRatio>
Example:
Manual operation:
[:SOURce<hw>]:AWGN:FREQuency:RESult?
In CW inerferer mode, queries the actual frequency of the sine.
The actual frequency may differ from the desired frequency, since the resolution is limi-
ted to 0.7 Hz.
Return values:
<Result>
