Jitter Measurement and Timing Analysis

Understanding timing jitter has become a mandatory part of high-speed communications system design as today’s serial data standards require extensive jitter compliance tests. Tektronix' comprehensive test instrumentation portfolio enables you to meet your design goals and compliance requirements – fast.

DPOJET Jitter & Timing Analysis for Real-Time Oscilloscopes: DPOJET enables engineers to debug and characterize timing, jitter, and noise in computer, mobile, and data communication system designs.

TekScope Anywhere^TM Waveform Analysis: Users now have the flexibility to perform timing, eye, and jitter analysis outside the lab that can easily be shared between team members in a networked environment.

80SJNB Jitter, Timing, and SDLA Visualizer Analysis for Sampling Oscilloscopes: 80SJNB is an all-purpose tool that enables engineers to specify a de-embed filter, Time Domain Waveform or S-Parameter for channel embedding. 80SJNB also performs timing, noise and mask testing analysis to get a 3-D view of the eye diagram performance for deep, accurate evaluation on signals with speeds beyond 50GHz.

JMAP Jitter Mapping and Decomposition Analysis for BERTScope BSA Series: Unlike a traditional BERT, BERTScope utilizes unique JMAP analysis to provide jitter decomposition into its random and deterministic components for a deeper understanding of errors on long patterns.
