7.2 Additive White Gaussian Noise (AWGN) - Noise Gen-
erator
This section introduces the concept of the AWGN generator and describes the settings
for generation of noise, sine wave interferer and adding noise to the generated signal.
The AWGN requires option R&S SGT-K62.

7.2.1 About the AWGN Generator

The R&S SGT allows you to superimpose noise on the generated signal. The built-in
internal noise generator generates an AWGN signal (Additive White Gaussian Noise)
with selectable bandwidth and adds it to the digital baseband signal. The main charac-
teristic of this kind of noise signal is the Gaussian distribution of the noise power den-
sity and uniform frequency distribution.
AWGN modes
The AWGN generator generates signal in one of the following different modes:
●
"Additive Noise": the generated noise signal superimposes the interference-free
useful signal
