Component Description/Result
20 TN Measures the total level error of the input signal. It is defined as the ampli-
tude deviation between the amplitude of the input signal at the decision
time point and its corresponding reference level.
21 DN The reproducible portion of the overall level error of the input signal. It con-
sists of the data-dependent noise, the periodic noise components and the
other bounded uncorrelated jitter components.
22 DDN Consists of inter-symbol interface noise and level distortion. It depends on
the symbol sequence. ISIN is an effect whereby past symbols have an
influence on future symbols.
LD is a mismatch between rising and falling signal transitions due to refer-
ence level mismatch or other imbalances between transitions.
23 LD A measure of imbalance between different symbol levels. It is defined as
the difference between the average level errors of the symbols one and
zero.
24 PN Periodic noise is typically caused by crosstalk from periodic signal sources
to the transmitter or transmission line. It represents the harmonic portion of
the overall level error.
25 ISIN The level difference between the highest and the lowest level error of a
symbol, i.e. one or zero.The largest value across all symbols is the mea-
surement result.
26 DDN + PN Data-dependent noise plus periodic noise is the combined effect of both jit-
ter types.
Note that DDN+PN equals deterministic noise minus other bounded uncor-
related noise.
DDN+PN spectrum is a useful approximation of the deterministic noise
spectrum fot negligible small other bounded uncorrelated noise.
27 (O)BUN Composite impact of all unknown but deterministic portions of the overall
time interval error of the input signal. It consists of any disturbance that
comes from a deterministic source but cannot be reproduced from the input
signal. Often it is caused by crosstalk from other data signals.
28 (O)BUN (δ-δ Other bounded uncorrelated Dual-Dirac noise (O)BUN (δ- δ) is an industry
standard approximation to the other bounded uncorrelated jitter measure-
ment. It is calculated by fitting a model of two overlapping, equally large
Gaussian distributions to the observed RN+(O)BUN histogram. The calcu-
lated value is the amplitude difference between the two distributions center
points.
29 RN Consists of any influence that cannot be predicted with model parameters.
Usually, this noise component follows a Gaussian probability distribution.
The algorithm computes the standard deviation and the peak-peak value of
the level error (LE) caused by RN within the analyzed waveform.
