[:SOURce<hw>]:AWGN:POWer:MODE <Mode>
In Additive Noise (
SOUR:AWGN:MODE ADD
) mode, selects the mode for setting the
noise power.
Parameters:
<Mode> CN | SN | EN
CN|SN
The noise power is set on the basis of the value entered for the
carrier/noise or signal/noise ratio
(
SOURce:AWGN:CNRatio|SNRatio
).
Whether a selection of C/N or S/N is enabled, depends on the
selected Display Mode (
AWGN:DISP:MODE BB|RF
)
EN
The noise power is set on the basis of the value entered for the
ratio of bit energy to noise power density (
AWGN:ENR
).
*RST: CN|SN
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 297
[: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.
