N5400B EZJIT Plus Jitter Analysis Software Option

Analysis capability

• Automated data rate and pattern detection of repetitive data signals, and the arbitrary data analysis mode allows for RJ/DJ separation on non-repetitive and long data waveforms
• New tail-fit jitter separation algorithm properly separates random from deterministic jitter even in difficult cross talk situations
• Measure random jitter (Rj), deterministic jitter (Dj), bounded uncorrelated jitter (BUJ), and many more jitter components

• Oscilloscope random jitter removal uses the waveform’s risetime to properly determine the oscilloscope's jitter contribution and remove it, and the fixed random jitter tool, gives users more flexibility in their crosstalk analysis

Display

• Composite histogram views of separated RJ, PJ, DJ, DDJ, DCD and ISI jitter subcomponents
• Bathtub curve of total jitter versus eye-opening down to 10^-18 BER
• Bathtub curve comparison of actual data versus tail-fit and spectral method jitter separation
• Random jitter threshold view to see the waveforms jitter spectrum and deterministic components being removed

Clock recovery

• Constant
• 1st or 2nd order PLL (JTF and OJTF)
• Equalized 1st and 2nd order PLL (with purchase of N5461B serial data equalization software)

Automation

• Setup wizards for full user control over measurement type, clock recovery method and jitter measurement voltage threshold
   

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. EZJIT jitter analysis software 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.

EZJIT Plus 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.

EZJIT Plus now comes standard 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.
