501 Operating Manual 1407.6062.32 ─ 08
Parameters:
<Mode> CN | SN | EN
CN|SN
available for mode Additive Noise (
SOUR:AWGN:MODE ADD
).
The noise level is set on the basis of the value entered for the
carrier/noise or signal/noise ratio (
AWGN:CNR|SNR
).
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 level 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 level is set on the basis of the value entered for the car-
rier/noise ratio (
AWGN:CNR
).
[:SOURce<hw>]:AWGN:POWer:NOISe <Noise>
Available for modes Additive Noise, Noise Only and CW Interferer (
SOUR:AWGN:MODE
ADD|ONLY|CW
).
This command sets or queries the noise level in the system bandwidth depending on the
selected modes:
●
"Additive Noise" and "CW Interferer" mode (
SOUR:AWGN:MODE ADD|CW
)
– "Reference Mode Carrier" (
SOUR:AWGN:POW:RMOD CARR
)
The command queries the noise/interferer level which is derived from the entered
C/N value. The carrier level is set with command
SOUR:AWGN:POW:CARRier
.
– "Reference Mode Noise" (
SOUR:AWGN:POW:RMOD NOIS
The command sets the noise/interferer level. The level of the carrier signal is
derived from the entered C/N value.
●
"Noise Only" mode
The command sets the noise level.
Parameters:
<Noise> float
Default unit: dBm
Example: SOUR:AWGN:POW:NOIS?
queries the noise level in the system bandwidth.
Response:
10
the noise level in the system bandwidth is 10 dBm.
[:SOURce<hw>]:AWGN:POWer:NOISe:TOTal?
Available for modes Additive Noise and Noise Only (
SOUR:AWGN:MODE ADD|ONLY
)
SOURce Subsystem
