Manual operation: See "Noise Power (System Bandwidth) / Interferer Power"
on page 299
[:SOURce<hw>]:AWGN:POWer:NOISe:TOTal?
In Additive Noise and CW Interferer (
SOUR:AWGN:MODE ADD|CW
) modes, queries the
noise power in the total bandwidth.
Tip: Use the command
[:SOURce<hw>]:AWGN:DISP:ORESults
to define the ana-
log or digital signal path before.
Return values:
<Total> float
Range:
-145 to 20
Increment: 0.01
*RST:
-30
Example: SOURce:AWGN:POWer:NOISe:TOTal?
queries the noise power in the total bandwidth.
Response:
15
the noise power in the total bandwidth is 15 dBm.
Usage: Query only
Manual operation: See "Noise Power (Total Bandwidth) - AWGN" on page 300
[:SOURce<hw>]:AWGN:POWer:RMODe <RMode>
In Additive Noise and CW Interferer (
SOUR:AWGN:MODE ADD|CW
) modes and Display
Mode set to RF (
AWGN:DISP:MODE RF
), selects the mode for setting the interfering
signal.
Parameters:
<RMode> CARRier | NOISe
CARRier
The carrier power is kept constant when the C/N value or Eb/N0
value is changed. The noise power is adjusted.
NOISe
The noise power is kept constant when the C/N value or Eb/N0
value is changed. The carrier power is adjusted.
*RST:
CARRier
Example: SOURce:AWGN:MODE ADD
selects Additive Noise mode.
SOURce:AWGN:DISP:MODE RF
sets the display mode to RF
SOURce:AWGN:POWer:RMODe NOISe
selects Reference Mode Noise. The noise power is kept con-
stant when the C/N value or Eb/N0 value is changed. The carrier
power is adjusted.
Manual operation: See "Reference Mode - AWGN" on page 297
