N1091CKCA IEEE 802.3ck Measurement and Debug Application

Characterize IEEE 100/200/400 Gb/s Electrical TX Designs using N1000A DCA-X Wide-Bandwidth Oscilloscopes

Introduction

Several industry and IEEE standard associations have defined specifications for 100 Gb/s and over one lane on the Physical Medium Attachment (PMA) Sublayer & Physical layer. As an example, chip-to-chip or chip-to-module interface of 100/200/400 Gb/s designs, or backplane (KR) or shielded balanced copper cabling (CR) defined by IEEE 802.3ck.

The Keysight N1091CKCA IEEE 802.3ck software is a measurement application for the DCA-X equivalent-time sampling oscilloscopes designed to save time and money by automating 53 Gbaud PAM4 transmitter (TX) test measurements.

Transform Complexity into Simplicity

The N1091CKCA is an easy-to-use TX test application that:

• Saves time in understanding details of standards

• Reduces the time it takes to characterize your 53 Gbaud PAM4 design from hours to minutes

• Helps debug your device using custom configurations

• Automates optimization of CTLE + DFE equalizer settings

• Allows you to quickly generate HTML reports that summarize the performance of your device

Select Industry-leading Hardware

Configure your oscilloscope for single or multi-channel capability. The N1091CKCA application supports a variety of digital communication analyzer (DCA) oscilloscope configurations, including the N1000A DCA-X wide-bandwidth oscilloscope platform, N1060A precision waveform analyzer or the N104X 1/2/4 port remote heads and DCA-M family clock data recovery module. For return loss, the software controls an N1055A TDR module (or an economy or performance network analyzer) and performs S-parameter measurements. For more hardware configuration details, refer to the Ordering Guide in this document.

Select the Desired Software Test Suite

The N1091CKCA IEEE 802.3ck TX test application covers PAM4 transmitter measurements outlined in IEEE 802.3ck specifications. The tests are sorted conveniently by clause. Click on the desired test group, and the appropriate tests are offered in Select Tests (factory-installed options shown).

The N1091CKCA test application covers most TX tests outlined in the tables below. For a comprehensive and up-to-date list of specific tests covered by the application, download the N1091CKCA application from www.keysight.com, install it on a PC, and run the application in “Demo Mode”. No license (or hardware) is required to run the software application in “Demo Mode”.

Configure Your Measurements

Customize parameters that are specific to your setup, such as signaling rate, CTLE gain settings, and coefficient parameters used to determine linear fit pulse & steady-state voltage. Use default values or enter your own settings including the number of waveforms taken, jitter eye center definition, window shape and pattern symbol length. Choose Compliance mode to test within limits or choose Debug mode to test to your custom limits and adjust other test parameters.

Choose Your Tests

The N1091CKCA IEEE 802.3ck TX test application provides comprehensive coverage of PAM4 tests that are specific to the clause you are testing. You may click on all available tests, a group of tests, or select individual tests to run. The full test name appears in the test list and is also shown in the test results and reports. A description of the test and reference to the Standard is shown for each test.
