Programmable Noise Generators
J7000B Series
The J7000B jitter noise generator generates additive white Gaussian noise (AWGN) with a large crest factor to model “real world” random jitter. This random jitter is commonly referred to as Rj in the industry accepted jitter hierarchy model and managing Rj is critical to the performance and capability of high-speed communication busses and devices. Today’s high-speed digital circuit designers are challenged with narrow jitter tolerances to deliver high data rates with low bit error rate (BER). Designing a system that is not only compliant to industry specifications but also robust enough to handle jitter and maintain an acceptable bit error rate is a never ending challenge and only gets harder as frequency and data rate increase.
