Remote Control Commands
SOURce:AWGN Subsystem
Return values:
Example:
Usage:
float
Range: -145 to 20
Increment: 0.01
*RST: 0
SOURce:AWGN:POWer:SUM:PEP?
queries the peak envelope power of the overall signal.
Query only
Manual operation: See "Carrier + Noise PEP / Signal + Noise PEP (Total Bandwidth) /
Carrier + Interferer PEP / Signal + Interferer PEP" on page 127
[:SOURce]:AWGN:SLENgth
This command is available for mode Noise Only (SOUR:AWGN:MODE ONLY).
Sets the sequence length of the signal in samples.
The sequence length depends on the configured instrument. If the configured instrument
is changed, the value range of this parameter is changed as well.
Parameters:
Example:
integer
Range: 128 to 1073741824
Increment: 1
AWGN:MODE ONLY
activates the generation of a pure noise.
AWGN:STAT ON
switches on the generation of a pure noise.
AWGN:SLEN 1024
sets the sequence legth.
Manual operation: See "Sequence Length" on page 123
[:SOURce]:AWGN:SRATe
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.
Parameters:
Example:
float
Range: 400 to 250E6 bps
Increment: 0.001
*RST: 40E6
Default unit: Valid units are bps, kbps and Mbps.
AWGN:BRAT?
queries the bit rate which is used for calculation of the Eb/N0 value
from the C/N value.
