The LeCroy SDA II analysis package contains two methods for estimating total jitter and for breaking down jitter into random and deterministic components. This document describes the methods in non-mathematical language. Understanding SDA ll TECHNICAL BRIEF
Jitter Calculation Methods
Introduction
Dr. Alan Blankman
March, 2012 LeCroy’s SDA II Serial Data Analysis Package includes revised jitter
Rev 2 calculation methods and enhancements to the SDA user interface and
feature set.
Summary In SDA II, the jitter calculation methods now include the Spectral Method,
The LeCroy SDA II analysis which is part of MJSQ, a de facto industry standard for jitter
package contains two measurements. Users can now choose to use the spectral method or to
methods for estimating total use LeCroy’s NQ-Scale algo……
