TekExpress®and DPOJET 40GBase-CR4 features

Welcome to the TekExpress®40GBase-CR4 Compliance and Debug Solution Software application and DPOJET 40GB ase-CR 4 plug-in. These applications provide an automated, simple, and efﬁcient way to test interfaces and devices to the requirements of the IEEE 802.3-2012 section 85 and Annex 85A standard.

Key features and beneﬁts include:

An intuitive user interface and framework decreases testing time and learning curve

Provides measurements for electrical characterization of 40GBase-CR4 signal at TP2 and TP0

Provides both an automation solution (for compliance) and DPOJET option (for debug), saving up to 80% on testing time as com p ared to manual testing

Has ﬂexible parameter control for characterization and margin analysis (in user-deﬁned mode)

Supports N1N0 (4 <= N <= 12), PRBS7, PRBS11, PRBS15, PRBS20, PRBS23, and PRBS31 patterns in advanced/us er-deﬁned mode, and supports PRBS9, 8180, and 1010 patterns in compliance mode

Complete programm atic interface enables users to call 40G-CR4 functions using c ustom automation scripts

Performs autom atic signal validation before performing tests and displays an error message if the signal does not meet acceptable limits

Includes DPOJET setup ﬁles for 8180, 1010, and PRBS9 patterns to help set oscilloscope and load measurements (in DPOJET).

Creates detailed reports (.MHT or .PDF) for compliance record keeping, with ﬂexible reporting features such as appending t he report, auto-incrementing the report, and including user comments
