This command queries the noise level in the total bandwidth.
Return values:
<Total> float
Range: -145 to 20
Increment: 0.01
*RST: -30
Example:
SOUR:AWGN:POW:NOIS:TOT?
queries the noise level in the total bandwidth.
Response: 15
the noise level in the total bandwidth is 15 dBm.
Usage: Query only
[:SOURce<hw>]:AWGN:POWer:RMODe <RMode>
This command selects the mode for setting the interfering signal.
This command is available for modes "Additive Noise" and "CW Interferer"
(SOUR:AWGN:MODE ADD|CW) and Display Mode set to RF (AWGN:DISP:MODE RF).
Parameters:
<RMode> CARRier | NOISe
CARRier
The carrier level is kept constant when the C/N value or Eb/N0
value is changed. The noise level is adjusted.
NOISe
The noise level is kept constant when the C/N value or Eb/N0
value is changed. The carrier level is adjusted.
*RST: CARRier
Example:
AWGN:MODE ADD
selects Additive Noise mode.
AWGN:DISP:MODE RF
sets the display mode to RF
AWGN:POW:RMOD NOIS
selects Reference Mode Noise. The noise level is kept constant
when the C/N value or Eb/N0 value is changed. The carrier level
is adjusted.
[:SOURce<hw>]:AWGN:POWer:SUM?
Available for modes "Additive Noise" and "CW Interferer" (SOUR:AWGN:MODE ADD|CW)
This command queries the overall level of the noise signal plus useful signal.
Return values:
<Sum> float
Range: -145 to 20
Increment: 0.01
