For Custom Digital Mod signals the bit rate used for calculation of E
b
/N
0
value from C/
N value is determined by the selected standard (
SOURce:BB:DM:STANdard
) and can-
not be changed.
Parameters:
<EnRatio> float
Range:
-30 to 30
Increment: 0.001
*RST:
0
Default unit: dB
Example: AWGN:ENR 10
sets a ratio of bit energy to noise power density of 10 dB
[:SOURce<hw>]:AWGN:FREQuency:RESult?
This command queries the actual frequency of the sine in the CW Interferer mode.
The actual frequency may differ from the desired frequency, since the resolution is limited
to 0.7 Hz.
Return values:
<Result> float
Range:
-40E6 to 40E6
Increment: 0.01
*RST:
0
Example: AWGN:FREQ:RES?
queries the actual frequency of the interfering sine
Usage: Query only
[:SOURce<hw>]:AWGN:FREQuency:TARGet <Target>
This command sets the desired frequency of the sine in "CW Interferer" mode
(
AWGN:MODE CW
).
The resulting frequency may differ from the desired frequency because of the limited
frequency resolution of 0.7 Hz.
Parameters:
<Target> float
Range:
-40E6 to 40E6
Increment: 0.01
*RST:
0
Example: AWGN:FREQ:TARG 2kHz
sets a frequency of 2 kHz for the interfering sine.
[:SOURce<hw>]:AWGN:MODE <Mode>
This command selects the mode for generating the interfering signal.
