and stochastic noise
Jitter and noise cause misalignment of edges and levels, resulting in data errors.
Noise is by its nature unpredictable because it can have many different causes, from
signal interference caused by sudden voltage changes, to distortions introduced during
transmission.
It is important to be able to simulate noise-based malfunctions, for example, to identify
the additive noise produced by receiving systems—it is cheaper to lower the noise figure
than to increase the transmitter power! The Keysight 81150A and the Keysight 81160A
Pulse Function Arbitrary Noise Generators let you control the quality of the noise, to test
different cases, and according to various specifications.
White Gaussian noise is a good approximation to many real-world situations, and creates
mathematically traceable models, with statistical independent values. The Keysight
81150A and the Keysight 81160A Pulse Function Arbitrary Noise Generators provide
deterministic white Gaussian noise, with a signal repetition of 20 days or 26 days respec-
tively. You can decide on any arbitrary distribution, and trigger the noise to start when
you need it.
