Keysight and 86100DU-401
Advanced EYE Analysis Software
Provides a simple and accurate solution to the challenging process of measuring jitter
on very long patterns and performs precision mask testing using BER contours
86100 Series Option 401 is an advanced software application providing:
–– Compliant jitter measurements such as:
– Random Jitter (RJ)
– Deterministic Jitter (DJ)
– Total Jitter (TJ)
– J2 Jitter
– J9 Jitter
– Data Dependent Pulse Width Shrinkage (DDPWS)
–– Jitter measurements on long patterns, including PRBS23, PRBS31,
and live traffic.
–– Precision mask testing capability using BER contour- based masks.
Make accurate and compliant
jitter measurements on long
patterns.
To ensure that digital communications
systems approach error-free performance,
data test patterns that emulate actual
traffic are often used. Some of these test
patterns can be extremely long and can be
problematic for test instruments. Option
401 software makes precision jitter
measurements on long data patterns,
such as PRBS23, PRBS31, and live traf-
fic. By way of example, PRBS31 is often
used when testing 10GbE (802.3ae-2002),
40GbE/100GbE (802.3ba-draft), and SFP+
(SFF-8431).
The 86100C DCA-J and 86100D
DCA-X offer the optimum combination
of low intrinsic jitter, low noise, and wide
bandwidth. As a result, the DCA is the tool
of choice for making precision measure-
ments on high-speed digital designs.
Option 401 runs on an external PC, or DCA
mainframe, running Microsoft Office Excel
2003/2007. It extracts waveforms from the
DCA and processes them in MS Excel. For
the highest accuracy jitter measurements
the application leverages measurements
made by 86100C/D-200 Enhanced Jitter
Analysis (Jitter Mode). Alternatively, it can
also operate standalone if Jitter Mode is
not installed - the choice is yours!
Measure with confidence
using the accuracy and ease-of-
use of the 86100C and 86100D
Infiniium Digital Communication
Analyzer (DCA).
Accurate jitter measurements are achieved
as the result of accurate waveform
measurements and robust algorithms.
Standards like SFF-8431 continue to
evolve and new measurements are
often the result. Data Dependent Pulse
Width Shrinkage (DDPWS), a compo-
nent of Data Dependent Jitter (DDJ), is
reported by Option 401 when operating
together with 86100C/D-200.
