Gain insight into the causes of signal jitter to ensure high reliability of your design
With faster edge speeds and shrinking margins in today’s
high-speed digital designs, insight into the causes of jitter has
become critical for success. Using EZJIT and EZJIT Plus jitter
analysis software the Z-Series oscilloscopes help you identify and
quantify jitter margins 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 simplify and automate
RJ/DJ separation for testing against industry standards.
EZJIT Plus automatically detects embedded clock frequencies
and repetitive data patterns 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, a feature not available on any other real-time
oscilloscope today.
Use EZJIT software to extract spread spectrum clocks.
Measurement trends and jitter spectrum
EZJIT’s simple tools help you quickly analyze the causes of jitter.
Measurement trends allow you to see deeper views of factors
affecting measurements. Jitter spectrum is a fast method to find
the causes of jitter.
Two ways to separate jitter
EZJIT Plus comes with two ways to separate jitter: the spectral
method and the emerging tail fit method. Both methods allow
for simple separation of RJ and DJ, but the tail fit method
provides proper jitter separation in the unique case of bounded
uncorrelated jitter.
Unique RJ/DJ threshold view
EZJIT Plus also provides a unique threshold view of the jitter
spectrum with the threshold drawn on the chart. The spectral
view provides insight into the decision point of the separation and
works with both narrow and wide spectral separation.
Determine which algorithm fits your data best.
Real-time eye and clock recovery
Serial data analysis (SDA) software provides flexible clock
recovery including 1st and 2nd-order PLL and constant
algorithms. With a stable clock, you can look at real-time eyes
of transition and non-transition bits. Z-Series scopes with SDA
software also provide a new unique view of bits preceding an eye.
Flexible charts
EZJIT Plus displays up to 10 graphs with unique information. Use
them all to maximize your jitter analysis.
Jitter separation makes debugging your device easy.
