Basic Function Commands
Vector Modulation Subsystem—N5172B/82B ([:SOURce]:IQ)

:OUTPut:IMPairments:AWGN:BANDwidth|BWIDth

[:SOURce]:IQ:OUTPut:IMPairments:AWGN:BANDwidth|BWIDth
<value>
[:SOURce]:IQ:OUTPut:IMPairments:AWGN:BANDwidth|BWIDth?
This command sets the flat noise bandwidth, which is typically set wider than
the signal bandwidth. There will be roll-off of the noise outside of this
bandwidth.
Range

:OUTPut:IMPairments:AWGN:EBNO

[:SOURce]:IQ:OUTPut:IMPairments:AWGN:EBNO <value>
[:SOURce]:IQ:OUTPut:IMPairments:AWGN:EBNO?
This command allows the signal to noise ratio to be set using the Eb/No
(energy per bit over noise power density at the receiver) form. This requires the
signal bit rate to be set properly.
(SNR)dB = (Eb/No)dB + 10log(bitRate/signalBandwidth)

:OUTPut:IMPairments:AWGN:IBWidth

[:SOURce]:IQ:OUTPut:IMPairments:AWGN:IBWidth <value>
