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:
Mode
Selects the mode for generating the interfering signal.
"Additive Noise"
The AWGN noise signal with selectable system bandwidth is added
to the baseband signal.
"Noise Only"
The pure AWGN noise signal with selectable system bandwidth is
modulated to the carrier. The connection to the baseband is interrup-
ted.
"CW Interferer" A sine with a defined frequency offset is added to the baseband sig-
nal. The calculation of E

ratio is omitted.
Remote command:
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:
Minimum Noise/System Bandwidth Ratio
Available only for "Mode > Additive Noise" or "Mode > Noise Only".
