Agilent 86100CU-401 86100CU-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 86100CU 86100CU 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 PRBS23, PRBS31 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. 86100CU 86100CU Option 401 software makes precision jitter measurements on long data patterns, such as PRBS23 PRBS23, PRBS31 PRBS31, and live traffic. By way of example, PRBS31 PRBS31 is often used when testing 10GbE (802.3ae-2002), 40GbE/100GbE (802.3ba-draft), and SFP+ (SFF-8431 SFF-8431).

Measure with confidence using the accuracy and ease-of-use of the 86100C 86100C Infiniium Digital Communication Analyzer (DCA-J) Accurate jitter measurements are achieved as the result of accurate waveform measurements and robust algorithms. The 86100C 86100C DCA-J offers the optimum combination of low intrinsic jitter, low noise, and wide bandwidth, making it the tool of choice for making precision measurements on high-speed digital designs. The 86100CU-401 86100CU-401 application runs on an external PC, or 86100C 86100C DCA-J, running Microsoft(R) Office Excel 2003/2007. It extracts waveforms from the 86100C 86100C DCA-J and processes them in MS Excel. For the highest accuracy jitter measurements the application leverages measurements made by 86100C-200 86100C-200 Enhanced Jitter Analysis (Jitter Mode). Alternatively, it can also operate standalone if Jitter Mode is not installed - the choice is yours! Figure 2 Perform compliant jitter measurements easily and accurately using the 86100C 86100C DCA-J and 86100CU-401 86100CU-401 Advanced EYE Analysis Evolving standards, new measurements Standards like SFF-8431 SFF-8431 continue to evolve and new measurements are often the result. Data Dependent Pulse Width Shrinkage (DDPWS), a component of Data Dependent Jitter (DDJ), is reported by 86100CU-401 86100CU-401 when operating together with 86100C-200 86100C-200. www.agilent.com Calibrate stressed eye transmitters The dual-Dirac model is commonly used in technology standards to quickly and accurately estimate total jitter defined at a low BER such as TJ @ 1E-12 1E-12. However, calibrating a stressed eye transmitter with large amounts of jitter can often be a challenge for test equipment using this standards-based estimation technique. In the presence of increasing RJ injection, for example, reported DJ will tend to decrease and seem to "disappear" on BERTs and scopes using this model. J2 jitter, sometimes referred to as "99% Jitter" or "all but 1% for jitter", is sometimes used by engineers when calibrating stressedeye signals for receiver testing. Why? J2 "measures" jitter directly from histogram data rather than "estimating" jitter based on models. IEEE 802.3ae (2002) and draft specifications such as IEEE 802.3ba and SFF-8431 SFF-8431 are examples of standards that use this high probability jitter measurement. J9 Jitter is "all but 10E-9 10E-9" of the jitter distribution and is estimated at a BER of 2.5E-10 5E-10. 86100CU-401 86100CU-401 is capable of measuring jitter in excess of 0.7UI so it is an ideal solution for calibrating stressed eye transmitters. It also reports J2 and J9, thereby saving engineers from having to measure histogram data and calculate these parameters offline. Compliant BER-contour based mask testing Sampling scopes, due to their unmatched signal fidelity, continue to be the de facto standard for mask testing. However, some specifications like CEI 2.0 and XFP MSA, specify an eye mask test based on a specified BER such as 1E-12 1E-12. While these masks can be modified and run using traditional scope-based mask testing, it's now possible to perform BER-contour based mask testing using 86100CU-401 86100CU-401. 86100CU-401 86100CU-401 Measurements The application performs the following measurements: Jitter Measurements Total Jitter (TJ), Random Jitter (RJ), Deterministic Jitter (DJ), J2 Jitter (J2), J9 Jitter (J9), Data Dependent Pulse Width Shrinkage (DDPWS)* Optional Hardware: ·External PC ·82357B 82357B USB/GPIB Interface USB 2.0 Instrument control is made using either LAN or GPIB.
