N6473A OIF-CEI 4.0 Compliance Application  

For Infiniium Z-Series Oscilloscopes

Introduction

More and more industry and standards bodies have adopted pulse amplitude modulation 4-level (PAM4) to increase throughput within a given bandwidth compared to Non-Return-to -Zero (NRZ) technology. Working groups within the Optical Internetworking Forum - Common Electrical Interface (OIF-CEI 4.0) is one such group that has adapted PAM4 technology.  

Transform complexity into simplicity  

The Keysight Technologies, Inc. N6473A OIF-CEI 4.0 compliance application for Infiniium real-time oscilloscopes saves you time and money by automating the task of preforming PAM4 and NRZ compliance measurements. The N6473A OIF-CEI 4.0 compliance application for Infiniium real-time oscilloscopes is an easy-to-use oscilloscope application that:  

– Saves time in understanding details of standards

– Reduces the time it takes to characterize your PAM4 and NRZ design from hours to minutes

– Helps to debug your device using custom configurations

– Allows you to quickly generate early HTML reports summarizing your device characteristics

Debug and Verify Your Designs Quickly and Easily  

Select your measurement tools  

Choose from a wide array of high performance real-time oscilloscopes supporting up to 63 GHz and 160 GSa/s with the lowest noise floor in the industry. The N6473A OIF-CEI 4.0 compliance application can be configured to measure the S-parameters of your device under test as well as control vector network analyzers (VNA) to measure return loss.

Select the desired test suite  

The N6473A OIF-CEI 4.0 compliance application covers PAM4 and NRZ transmitter measurements outlined in OIF-CEI4.0 specification. 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).

N6473A-1FP performs PAM4 and NRZ transmitter tests outlined in:  

– OIF-CEI-56G-VSR-PAM4 (Very Short Reach interface)

– OIF-CEI-56G-MR-PAM4 (Medium Reach interface)

– OIF-CEI-56G-LR-PAM4 (Long Reach interface)

Configure your measurements  

Customize parameters that are specific to your setup, such as signaling rate and attenuation. Use default values or enter your own settings including number of waveforms taken, type of pattern, and pattern symbol length. Choose Normal mode to test within limits, or choose Debug mode to test to your custom limits and adjust other test parameters.

Choose your tests  

The N6473A OIF-CEI 4.0 compliance application provides comprehensive coverage of all PAM4 and NRZ 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/IA is shown for each test.
