Flat Noise Bandwidth

AWGN Setup

This feature allows you to add AWGN (Additive White Gaussian Noise) to a waveform.

Requires 2024.0801 license version.

Enabled

Enables /disables the AWGN feature.

SCPI Command	[SOURce]:RADio:AWU:WAVeform:IMPairment:AWGN:STATe ON|OFF|1|0 [SOURce]:RADio:AWU:WAVeform:IMPairment:AWGN:STATe?
Preset	OFF

Carrier to Noise Ratio

Set the power boost level of the carrier.

Available only when the AWGN Setup > Enabled checkbox is selected.

Carrier Bandwidth

Sets the bandwidth of the applied waveform. As this setting is used to calculate the correct noise power, ensure that this value is the correct bandwidth of applied waveform.

Available only when the AWGN Setup > Enabled checkbox is selected.

SCPI Command	[:SOURce]:RADio:AWU:WAVeform:IMPairment:AWGN:CBWidth <real> [:SOURce]:RADio:AWU:WAVeform:IMPairment:AWGN:CBWidth?
Couplings	Only applied when AWGN is enabled. When waveform is imported, the max value for Carrier bandwidth is sample rate of waveform/1.25.
Preset	40 MHz
State Saved	Yes
Min	1 Hz
Max	1 GHz
Resolution	1

Flat Noise Bandwidth

Sets the bandwidth of noise added to the signal. This setting is used to calculate the correct noise power.

Available only when the AWGN Setup > Enabled checkbox is selected.

SCPI Command	[:SOURce]:RADio:AWU:WAVeform:IMPairment:AWGN:FNBWidth <real> [:SOURce]:RADio:AWU:WAVeform:IMPairment:AWGN:FNBWidth?
Couplings	Only applied when AWGN is enabled. When waveform is imported, the maximum value for Flat Noise Bandwidth is sample rate of waveform/1.25.
Preset	40 MHz
State Saved	Yes
Min	1 Hz
Max	1 GHz
