Spring 2008 Jitter ExperimentMidterm presentation Performed by Greenberg Oleg Hahamovich Evgeny Supervised by Mony Orbah
Agenda • Objective • Exp. environment • Accomplished Tasks • Topics to be covered • Implementation difficulties • Time Table
Objective Creating an experiment environment, which will include theoretical introduction and practical exposure to the jitter subject, allowing the student to investigate and get familiar with Jitter types, components and sources
Experiment Environment Jitter created by FM Tabor Arbitrary Waveform Generetor 2571a Maximum frequency 100 MHz Sampling Rate 250 MS/s Ability to create different Modulation types Agilent Oscilloscope MS08104A Bandwidth 1 GHz Sample Rate 4 GS/s Customization Package, Jitter and Timing Analysis
Accomplished Tasks • Eye diagram comparing between eye diagram of a clean signal vs. “noisy” (modulated) signal Unmodulated signal FM modulated signal
Accomplished Tasks • Histogram - Histograms for different wave shapes - Histograms for different jitter measurement types TIE histogram for FM modulation by a sin wave Sin wave histogram
Accomplished Tasks • Relation between different jitter measurement types - Visualization of diff-int relation between jitter measurement types - Calculating ratio of Std Dev for different jitter measurement types
Modulation by Square wave TIE jitter trend Period jitter trend C2C jitter trend
Topics to be covered Implementation difficulties • DCD create and measure for different waveforms (tabor) • Bathtub curve theory and relation to eye diagram, BER explanation, extrapolation theory (ezjit+) • Methods for jitter separation - Dual Dirac model + tail fit method - Furrier transport (ezjit+)
Time Table • Implementing the uncovered parts of the experiment - DCD implementation option check ½ week - Bathtub curve 1 week - Jitter separation methods 1 week 2 weeks • Writing detailed documentation including step by step guidance to scope setup and measurement theory 2 weeks • Preparing final presentation 1 week Estimated deadline - mid. October
