N5400A EZJIT Plus Jitter Analysis Software Option

Product Status: Discontinued | Currently Supported
This product is no longer available

Key Features & Specifications

Analysis Capability

  • Automated data rate and pattern detection of repetitive data signals
  • 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
  • Fixed random jitter tool, gives users more flexibility in their crosstalk analysis


  • 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 N5461A Serial Data Equalization Software)


  • 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, combined with Keysight's Infiniium oscilloscope, 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.
