[:SOURce<hw>]:AWGN:BRATe <Brate>
This command sets the bit rate which is used for calculation of bit energy to noise power
ratio from carrier/noise ratio for Digital Standard signals
For "Custom Digital Mod" signals, the bit rate which is used for calculation can be queried
with this command.
Valid units are bps, kbps and mabps as well as b/s, kb/s and mab/s.
Parameters:
float
400 bps to 250E6 bps
0.001 bps
100 kbps
<Brate>
Range:
Increment:
*RST:
AWGN:BRAT?
queries the bit rate which is used for calculation of the Eb/N0 value
from the C/N value.
Example:
[:SOURce<hw>]:AWGN:BWIDth <Bwidth>
This command sets the system bandwidth. The noise signal at the level which corre-
sponds to the specified carrier/noise ratio is generated in the bandwidth specified here.
This command is available for modes Additive Noise and Noise Only (SOUR:AWGN:MODE
ADD|ONLY).
Parameters:
float
0.1 kHz
3.84 MHz
<Bwidth>
Increment:
*RST:
AWGN:BWID 10 MHz
sets a system bandwidth of 10 MHz.
Example:
