R&S SGT100A
State
Activates/deactivates the generation of an AWGN signal. The interferer (AWGN or CW
interferer, depending on the selected mode) is generated after the generator is activa-
ted.
Remote command:
[:SOURce<hw>]:AWGN:STATe
Mode
Selects the mode for generating the interfering signal.
"Additive Noise"
"Noise Only"
"CW Interferer" A sine with a defined frequency offset is added to the baseband sig-
Remote command:
[:SOURce<hw>]:AWGN:MODE
System Bandwidth
Available only for "Mode > Additive Noise" or "Mode > Noise Only".
Sets the RF bandwidth to which the set carrier/noise ratio relates.
Within this frequency range, the signal is superimposed with a noise signal which level
corresponds exactly to the set C/N or S/N ratio.
Remote command:
[:SOURce<hw>]:AWGN:BWIDth
Minimum Noise/System Bandwidth Ratio
Available only for "Mode > Additive Noise" or "Mode > Noise Only".
