Keysight Technologies IEEE 802.3 Ethernet Compliance and Debug Applications For 86100D DCA-X Oscilloscopes Data Sheet Introduction Easy-to-use oscilloscope application that lets you: –– Save time in understanding details of standards –– Reduce your IEEE 802.3 test times from hours to minutes –– Debug your device using custom configurations –– Characterize up to 10 lanes in multi-lane devices The greatly increased worldwide demand for video and data transfer has created new requirements for network expansion, driving innovative network elements for operation up to 100 Gb/s. New designs are facing more challenges while transferring these signals on printed circuit boards within hosts and modules, even for short distances. Measuring the IEEE 802.3 parameters can take a full day when manually characterized, and recalculating factors and equation-driven limits adds to the time the designer spends on testing. Keysight Technologies, Inc. created the N1081A, N1082A, N1083A and N1084A IEEE 802.3 Compliance and Debug Applications to simplify measuring these transmitter parameters and to obtain full results to test limits in a few minutes. This will keep you focused on getting your products to market knowing that your results are built on the heritage and consistency of Keysight measurement technology. 03 | Keysight | IEEE 802.3 Ethernet Compliance and Debug Applications - Data Sheet Transform Complexity into Simplicity Satisfying the comprehensive requirements of the IEEE 802.3 clauses can be very complex. The list of tests and test conditions vary from clause to clause, and each can be challenging to properly set up. The tests for each IEEE 802.3 clause vary, as do the test limits. An example of one group of tests from clause 93 is below. The time for your test development team to read and interpret the specification and then implement that understanding into test plans can take several months of effort. Parameter Signaling rate Differential peak-to-peak output voltage (max.) –– Transmitter disabled –– Transmitter enabled DC common-mode output voltage (max.) DC common-mode output voltage (min.) AC common-mode output voltage (RMS, max.) Differential output return loss (min.) Common-mode output return loss (min.) Hosts and modules have unique interface connectors and require compliance boards or test adapters to enable connection to test equipment. Designers endeavor to minimize the trace lengths on the compliance boards and cable lengths.

Connect your device through the recommended phase trimmers to have access to measurements with intrinsic jitter as low as 50 fs. For return loss, also connect the Economy or Performance Network Analyzer, which are controlled by the DCA-X for S-parameter measurements. Phase trimmers >> (recommended) Transmitter Select desired 10G/25G transmit clause The N108xA IEEE 802.3 applications cover all transmitter tests for 12 clauses and conveniently organize the tests by clause. Click on the desired test group, and the appropriate tests are offered in Select Tests. 05 | Keysight | IEEE 802.3 Ethernet Compliance and Debug Applications - Data Sheet Debug and Verify Your Designs Quickly and Easily (Continued) Configure your measurements Customize parameters that are specific to your setup, such as data rate and attenuation. Use default values or enter your own settings including number of waveforms or patterns taken; type of pattern; and whether or not to remove the effects of test cables. Choose Compliance mode to test within compliance limits or choose Debug mode to test to your custom limits and adjust other test parameters. Choose from more than 400 tests The tests required for each of the transmit and test signal groups are available. You can click on all tests, a group of tests or individual tests. The full test name appears in the test list and is shown in the test results and reports. A description of the test and reference to the IEEE 802.3 clauses are shown for each test. 06 | Keysight | IEEE 802.3 Ethernet Compliance and Debug Applications - Data Sheet Debug and Verify Your Designs Quickly and Easily (Continued) Measure challenging parameters fast Simply follow the steps and click Run Tests.

Share a report that shows the test conditions, summary of pass/fail, summary of all tests, and details for each test. Many include the appropriate screen shot of the measured parameter. 07 | Keysight | IEEE 802.3 Ethernet Compliance and Debug Applications - Data Sheet Debug and Verify Your Designs Quickly and Easily (Continued) Control your device or other equipment The Automation tab lets you enter commands to control external devices or equipment, further sequence your tests, or to control timing. See device performance in one view In a few minutes, you’ll have test results showing which parameters passed or failed and the margin compared to limits. These results will provide immediate insight into how you’ll need to improve your design to meet the challenging tests in the IEEE 802.3 clauses. 08 | Keysight | IEEE 802.3 Ethernet Compliance and Debug Applications - Data Sheet More Features to Further Streamline Your Development Utilize test adapters Development and characterization of advanced integrated circuits is timeconsuming and expensive. Designers utilize test adapters to fully characterize their parts for use in their own or their customer’s circuits. For more information about these adapters, please visit http://shop.wildertech.com/category_s/42.htm. …or host and module compliance boards By pairing your test adapter or compliance board with the 86100D, 86108B and N108xA software, you will have the simplest and most powerful solution available to optimize your designs and offer the best products to your customers. Phase trimmers and a pair of cables complement your setup for the most consistent and accurate measurements. Host FPGA Host compliance board or test adapter 09 | Keysight | IEEE 802.3 Ethernet Compliance and Debug Applications - Data Sheet More Features to Further Streamline Your Development (Continued) Configure your solution in three ways The hardware and software architecture provides wide flexibility. You may install the N108xA on the mainframe, which includes FlexDCA, or the N108xA on your PC, controlling FlexDCA on the DCA, or install both N1010A FlexDCA and N108xA on your PC. This lets you use your PC for more processing power and other applications, or you can have all measurement capability consolidated into a compact solution. The ENA/PNA is controlled by the N108xA via the PC or the DCA. Conveniently de-skew your cables Skew between the true and complement signals will often degrade your measured performance. While you need to characterize performance with the DUT skew included, the N108xA guides you to quickly de-skew your test cables using phase trimmers or to de-skew the N1045A or 86118A-H01 remote heads for best results.
