This is an advanced vertical noise, phase noise, and timing jitter test package option for D9010BSEO Infiniium Offline, which is a prerequisite for this application. View the datasheet to learn more.

With faster edge speeds and shrinking data valid windows in today's high-speed digital designs, insight into the causes of jitter has become critical for success. This jitter analysis software, combined with Keysight's Infiniium oscilloscopes, is a key tool for identifying and quantifying jitter components that affect the reliability of your design. Time correlation of jitter to the real-time signal makes it easy to trace jitter components to their sources. Additional compliance views and a measurement setup wizard now simplify and automate RJ/DJ separation for testing against industry standards.

This software automatically detects embedded clock frequencies and repetitive patterns of the data on the oscilloscope inputs and calculates the level of data-dependent jitter (DDJ) that is contributed to the total jitter (TJ) PDF by each transition in the pattern. It also comes with both spectral and tail-fit jitter separation algorithm.

Every waveform is different. As a result, having the flexibility of multiple jitter separation solutions means better answers for each individual waveform. Use the new tail-fit algorithm to properly identify and measure aperiodic bounded uncorrelated jitter, which is especially useful if the waveform is being influenced by cross-talk.

The Phase Noise analysis feature measures phase noise in a clock source. Phase noise measurement results are presented in a log frequency plot where the amplitude units are dBc/Hz (decibels relative to the carrier power normalized to a 1 Hz bandwidth). Phase noise is one of the most important figures of merit of a signal generating device and can be a limiting factor in a mission-critical application within aerospace and defense, as well as in communications.
