Analysis Tools: EZJIT Complete (Standard on DSA Models)
Discover signal anomalies to the noise of the waveform
Noise analysis with EZJIT Complete software for insight into the sources of noise in the signal.
More than your standard jitter package
Key measurements
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. 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.
With EZJIT Complete, Z-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
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 – deviating 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 techniques 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 frequency domain and extract
random components. Dual-Dirac modeling techniques are also
carried from the jitter domain and used in the interference
domain.
