Enable
Enables/disables AWGN insertion via the fading module.
Remote command:
CONFigure:EVDO:SIGN<i>:FADing:AWGN:ENABle
Min. Noise/System Bandwidth Ratio
Sets the minimum value of noise bandwith to system bandwidth ratio.
Remote command:
CONFigure:EVDO:SIGN<i>:FADing:AWGN:BWIDth:RATio
Noise Bandwidth
Total level of the AWGN interferer within the channel bandwidth (the spectral density
covering the receive band and 5 MHz outside the band).
The properties of the AWGN interferer comply with the requirements of 3GPP2
C.S0032, section 6.4.4 (e.g. minimum bandwidth 1.8 MHz, flatness less than ±1 dB,
frequency resolution 1 kHz, output range -20 dBm to -95 dBm).
Remote command:
CONFigure:EVDO:SIGN<i>:FADing:AWGN:BWIDth:NOISe?
Effective Signal Bandwidth
Displays the efective bandwidth of forward link.
Signal/Noise Ratio
Displays the signal to noise ratio resulting from the configured AWGN level and the
base level of the forward link signal generator.
