SEEj™ - Accurate RjDj Decomposition with Multi-vendor Correlation

"One thing that you may not be aware of - on the day we got M1 loaded and running on the scope, we learned more about our jitter components than in three months of testing using other instruments and approaches. There were clear periodic jitter components, and they could be easily tracked to their sources by matching jitter frequencies to chip operations and power fluctuations." - M1 Customer

No other tool provides RjDj Decomposition insight like M1™

  • ASA spent nearly two years developing our own decomposition method (SEEj), starting from real engineering first principles.
  • SEEj is the only tool that provides true correlation by using the same algorithm on all major manufacturers’ real-time oscilloscopes, digitizers, and EDA simulation tools.  This simply isn't possible with the manufacturer's tools (if they even provide RjDj capability), because each vendor uses their own proprietary algorithm.
  • M1 is the only jitter analysis tool that provides its user with RjDj Convergence Indicators, for almost 10 yrs now - others are just beginning to understand that RjDj measurement is a convergent process.

SEEj™ circumvents vulnerabilities in other methods

  • Only ASA allows users to plot RjDj values versus time to provide insight into RjDj convergence and stability.
  • Only ASA has validated the convergence performance of its RjDj Decomposition algorithm.

 No other tool has been validated across such a wide range

  • ASA developed the single most aggressive methodological validation ever for SEEj
  • ASA’s Data-jitter Algorithm Validation Engine (DAVE) breaks jitter-space up into ~300,000 regions over 6 dimensions and tests/calibrates SEEj across all of them.  Other vendors have tested against a maximum of 37 points specifically chosen in the 'sweet spot' of their algorithm; some may not have performed any validation testing at all...
  • SEEj’s innovative neural network calibrates decomposition accuracy to less than 5% or 0.002 UI over the vast majority of jitter space.
  • The unique Decomposition Performance Explorer (DPE), free for download, lets you explore how accurate SEEj is for your conditions.
