Analysis tools: EZJIT, EZJIT + and SDA (standard on DSA models)
Gain insight into the causes of signal jitter to ensure high reliability of your design
With faster edge speeds and shrinking
data-valid windows in today’s high-
speed digital designs, insight into the
causes of jitter has become critical
for success. Using EZJIT and EZJIT +
jitter analysis software the Q-Series
oscilloscopes help you identify and
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 fac-
tors affecting measurements. Jitter spectrum is a fast method to
find the causes of jitter.
Two ways to separate jitter
EZJIT + comes with two ways to separate jitter: the industry
standard Dual-Dirac method and the emerging tail-fit method.
Both methods allow for simple separation of RJ and DJ, but the
tail-fit method provides jitter separation in the unique case of
non-symmetrical histograms.
Unique RJ/DJ threshold view
EZJIT + also provides a unique spectral view of the jitter spec-
trum with the threshold drawn on the chart. The spectral view
provides insight into the decision point of the separation and
allows for narrow or wide, tail-fit or Dual-Dirac.
Real-time eye and clock recovery
Serial data analysis (SDA) software provides flexible clock
recovery including 1st and 2nd-order PLL and constant algo-
rithms. With a stable clock, you can look at real-time eyes of
transition and non-transition bits. Q-Series scopes with SDA
software also provide a new unique view of bits preceding an
eye.
8b/10b protocol
Serial data analysis software comes complete with 8b/10b
protocol and decoding. The analysis allows you to search and
trigger on the event you are looking for.
quantify jitter components 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 test-
ing against industry standards.
EZJIT Plus automatically detects
embedded clock frequencies and
repetitive data patterns on the oscil-
loscope 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.
