Analysis tools: EZJIT Complete (standard on DSA models)
Discover signal anomalies to the noise of the waveform
More than your standard jitter
package
In order to efficiently determine
root cause for any type of signal
degradation in the amplitude domain,
you must first determine whether
the problem is caused by random
or deterministic sources. In order to
help you accomplish this task, EZJIT
Complete takes analysis techniques
used in the time domain (jitter
analysis) and extends them into the
amplitude domain.
More than just an eye contour
EZJIT Complete is an in-depth view into
impairments related to signal levels –
either logic ones or logic zeroes – deviat-
ing from their ideal positions. Some tools
simply provide a view of an eye contour,
but provide no real measurement data
other than nice graphics.
EZJIT Complete uses separation tech-
niques to allow each bit to be examined
to determine correlated effects and
to make multiple measurements on
individual bits to determine uncorrelated
effects. Use FFTs to analyze the fre-
quency domain and extract random com-
ponents. Dual-Dirac modeling techniques
are also carried from the jitter domain
and used in the interference domain.
Key measurements
With EZJIT Complete, Q-Series
scopes offer the following unique
measurements:
• Total interference (TI)
• Deterministic interference (DI)
• Random noise (RN)
• Periodic interference (PI)
• Inter-symbol interference (ISI)
• RIN (dBm or dB/Hz)
• Q-factor
