597Operating Manual 1176.8016.02 ─ 17
Example:
AWGN:DISP:MODE RF
sets the display mode to RF
SOUR:AWGN:POW:MODE CN
the noise power is set on the basis of the value entered for the
carrier/noise ratio (AWGN:CNR).
Manual operation: See "Set Power via - AWGN " on page 311
[:SOURce<hw>]:AWGN:POWer:NOISe <Noise>
Sets or queries the noise power in the system bandwidth depending on the selected
mode:
●
SOUR:AWGN:MODE ADD|CW
–
SOUR:AWGN:POW:RMOD CARR
Queries the noise/interferer power which is derived from the entered C/N value.
Use the command SOURce:AWGN:POWer:CARRier to set the carrier power.
–
SOUR:AWGN:POW:RMOD NOIS
Sets the noise/interferer power. The power of the carrier signal is derived from
the selected C/N value.
●
"Noise Only" mode
The command sets the noise power.
Parameters:
<Noise> float
Increment: 0.01
Default unit: dBm
Example:
SOURce:AWGN:POWer:NOISe?
queries the noise power in the system bandwidth.
Response: 10
the noise power in the system bandwidth is 10 dBm.
Manual operation: See " Noise Power (System Bandwidth) / Interferer Power "
on page 314
[: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.
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.
