D9020JITA Information

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. The Keysight D9020JITA jitter analysis software, combined with Keysight's Infiniium 90000, V-, Z- or UXR-Series oscilloscopes, is a key tool for identifying and quantifying jitter components that affect the reliability of your design. The time correlation of the 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.

The Keysight D9020JITA jitter analysis 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.
