574 Operating Manual 1403.7458.32 ─ 14
Example: AWGN:CNR 10
sets a carrier/noise ratio of 10 dB.
Manual operation: See "Carrier/Noise Ratio / Signal/Noise Ratio" on page 298
[:SOURce<hw>]:AWGN:DISP:MODE <Mode>
Selects the display mode to Bseband or RF.
Parameters:
<Mode> RF | BB
*RST:
RF
Example: AWGN:DISP:MODE RF

Manual operation: See "Display Mode - AWGN" on page 296
[:SOURce<hw>]:AWGN:DISP:ORESults <OResults>
(requires option R&S SMJ-B18, Baseband Digital I/Q Out)
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> ANALog | DIGital
*RST:
ANALog
Example: SOURce:AWGN:MODE ONLY
activates the generation of a pure noise for path A.
SOURce:AWGN:DISP:MODE BB
sets the display mode
SOURce:AWGN:DISP:ORESults DIGital
displays the output results of the digital signal of path A.
Manual operation: See "Display Output Results For - AWGN" on page 296
[:SOURce<hw>]:AWGN:ENRatio <EnRatio>
In Additive Noise mode, sets the ratio of bit energy to noise power density.
Depending on the selected reference mode either the noise power (
AWGN:POW:RMOD
NOISe
) or the carrier power (
AWGN:POW:RMOD CARRier
) is adjusted to the set E
b
/N
0
ratio.
●
AWGN:POW:RMOD CARRier
the noise power is adjusted to the set E
b
/N
0
ratio and the carrier power is kept con-
stant.
