N8815A Infiniium 10GBASE-KR 64b/66b and Link Training Decode Software

Introduction

64b/66b encoding is a principal line code that is used in data networking and transmission. 64b/66b encoding is the principal encoding scheme behind the 10GBase-KR (x1/x4) technology as it achieves DC balance across a serial stream. The 64b/66b encoding also has less overhead than the 8b/10b encoding scheme.

Keysight Technologies, Inc. N8815A Infiniium protocol viewer software for 10GBase-KR Ethernet is the only 64b/66b protocol decoder technology available on a real time oscilloscope, providing time-correlated views of physical layer and transaction layer errors.

You get packet-level decode for 10GBASE-KR 64b/66b and link training decode Ethernet signals built into a real-time oscilloscope. This software provides you with a fast, easy way to isolate signal integrity problems from logic-level coding errors simultaneously on up to four lanes of serial data streams. This capability allows you to test, debug and characterize your designs to the logic and link layer. The N8815A Infiniium protocol decoder software is designed to work with 10GBase-KR Ethernet technologies. It also comes with the unique ability to identify PRBS signal lengths to verify the correct signals are being passed though the DUT.

Features

The N8815A Infiniium protocol decoder software offers several features to simplify the validation of your 10GBASE-KR 64b/66b designs:

• Setup wizard for quick setup, configuration and test
• Packet-level decode of primitives as well as link and transaction layers
• Serial data analysis with 64b/66b bit streams
• Differential Manchester Encoding (DME) capability for link training decode
• Training Frame Decode

Comprehensive Decode Capability

With the N8815A Infiniium 10GBASE-KR 64b/66b protocol decoder software, you can use the same oscilloscope you use for everyday debugging and signal quality testing to perform protocol-level viewing. The software automatically decodes symbols, packets and primitives and provides informative results. It includes decode of reserved bit settings during training sequences and speed negotiation, greatly simplifying debugging of link training failures.

Some of the difficulties in validating 10GBase-KR communication links are determining if link failures or instability is due to electrical problems or logic-level problems. The N8815A Infiniium 10GBASE-KR 64b/66b protocol decoder and link training software allows you to analyze the root cause of these issues with a single piece of test equipment.
