scope:

The standard defines specifications, modeling methods and terminology for the dispersion of specified instants of repetitive and/or periodic signals in electronics, telecommunications and measurement, which is referred to as jitter and phase noise.

Purpose

The purpose of the standard is to facilitate accurate and precise communication concerning jitter and phase noise and the models for measuring them. Because of the broad applicability of such terms in the electronics industries (such as computer, telecommunication, and measurement instrumentation industries), developing unambiguous definitions and the presentation of models for their measurement is important for communication between manufacturers, users and consumers.
