Component Description/Result
13 DDJ +PJ 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.
14 (O)BUJ 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.
15 (O)BUJ (δ-δ) Other bounded uncorrelated Dual-Dirac jitter (O)BUJ (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 RJ+(O)BUJ histogram. The calcula-
ted value is the amplitude dif
ference between the two distributions center
points.

RJ Consists of any influence that cannot be predicted with model parameters.
Usually, this jitter component follows a Gaussian probability distribution.
The algorithm computes the standard deviation and the peak-peak value of
the TIE caused by RJ within the analyzed waveform.
Noise components (option R&S
RTO6-K134)
17 EH@BER Returns the vertical eye opening at the user-defined BER.
18 RN+(O)BUN Random noise plus (other) bounded uncorrelated noise or (other) bounded
uncorrelated noise is the combined ef
fect of both noise types.
If periodic components are activated RN + OBUN are displayed, otherwise
RN + BUN.
RN + (O)BUN is typically used, if track or spectrum plots are desired. Both
plots are not available for RN only or (O)BUN only components as the time
dependencies of these noise types are unknown. RN + (O)BUN spectrum
is a useful approximation of the RN spectrum for negligible small (O)BUN.

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.
