Customer Needs - Increasing Complexity Compare PCI, PCI Express activity over the same time interval . . .
Traditional voltage vs. time display is insufficient for insight into signaling activity
► Verify clean transitions► Measure setup and hold
times
► 300 bits in same interval► Recover spread spectrum
clock embedded in data► Sort transition, non-transition

Why is Jitter Noise Floor important? JNF establishes the lower limit of jitter measurements you can make
using the oscilloscope.
Includes effects of noise, aperture uncertainty, time base stability, and interleaving error.
High Performance Real Time oscilloscopes have software that extracts the clock from serial data post-capture
– JIT3v2, RT-Eye™v2
Time Interval Error (T.I.E.) measures the timing of all edges captured in the memory.
How is JNF measured on a real signal? A very stable clock is acquired. The T.I.E of all edges is measured. The standard deviation of this TIE is the JNF, the lower limit of jitter measurements on this scope.
Like any real measurement, the characteristics of the device measured effect the results.
High speed clock directly from the BERT is used. – Sine waves are not valid because they do not represent fast edges. – Data signals are not valid because they include data-dependent jitter.
