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.
