Description

The Keysight M809228CA conformance receiver test application is designed to assist and simplify the stress signal calibration used for testing the inputs of OIF CEI-28G- VSR (host and module) as well as 28G-SR,-MR and 25G-LR interfaces.

The conformance application provides a user interface menu with the flexibility of choosing either compliance or debug mode. It reduces user interaction to a minimum and performs all required calibration routines and compliance testing automatically by remote controlling all required instruments. A wide range of hardware configurations is supported, thus protecting your investment.

The test application utilizes the same framework for the graphical user interface like most of Keysight transmitter test applications reducing training time by providing a common look and feel. When a user is required to perform setup changes, the user is guided by diagrams as well as text to minimize errors. Results of the individual calibration steps and tests are presented in tabular form as well as graphical form, where appropriate. Calibrations and test results can be stored in projects and recalled at a later point in time. The application can generate an HTML based test report.

Calibrations and Tests Covered by M809228CA Receiver Test

CEI-28G-VSR (host and module)

The CEI 28G-VSR is a high-speed chip-to-module electrical interface with low-voltage logic. It is applicable for data lanes supporting bitrates from 19.60 to 28.10 Gsym/s using NRZ coding over printed circuit boards (PCB). The test transmission range has a minimum value of 100 mm for host PCB trace plus one connector and has a minimum value of 50 mm PCB trace module. The most common case is a host chip connected to a module chip via SFP+ or QSFP fixtures.

For more details, refer to “Implementation Agreement OIF-CEI-03.1”-Clause 13 CEI 28G -Very Short Reach (VSR) Interface”.

Keysight M809228CA Compliance Receiver Test Application provides the following calibrations and tests for 28G-VSR Host and Module compliance. All calibration steps are automated. The test application prompts the user whenever user interaction is required for connecting or modifying the test setup. Detailed connection diagrams and instructions are provided by the test application.  The calibrations are implemented according to OIF-CEI-4.0 Common Electrical I/O (CEI) – Electrical and Jitter Interoperability Agreements, December 27, 2017 (Chapter 13)
