Spectral Jitter
Spectral Jitter - Concepts
The Spectral Jitter measurement allows you to analyze the jitter inherent in the
output signals of your device under test (DUT) as a function of the frequency. This
measurement can be used for investigation of the behavior of the DUT, for example
to identify crosstalk effects.
Spectral Jitter Analysis
The Spectral Jitter measurement provides a method for investigating the spectrum
of the jitter, i.e. its power distribution over frequency.
Deterministic jitter can be caused by repetitive data patterns. It can also be caused
by internal or external periodic effects.
