Analysis Tools: EZJIT, EZJIT Plus and SDA (Standard on DSA Models)

Use EZJIT software to extract spread spectrum clocks.

Determine which algorithm fits your data best.

Jitter separation makes debugging your device easy.

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.

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.

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.
