Keysight Technologies Quickly Validate Designs for DOCSIS 3.1 Compliance Application Brief Accelerate research and development and design verification test of DOCSIS 3.1 designs with a cost- effective, standards- based measurement solution, that provides high speed, wide bandwidth, deep memory and flexibility. 02 | Keysight | Quickly Validate Designs for DOCSIS 3.1 Compliance - Application Brief Abstract The latest version, DOCSIS 3.1, of the Data Over Cable Service Interface Specification (DOCSIS) standard, has now been officially released. Designing DOCSIS 3.1-based transmitters, receivers and components, and verifying their performance against the new standard requires stringent testing - a process made more com- plex by the standard's adoption of new technologies and the need for backward compatibility with previous DOCSIS versions. This document describes the Keysight Technologies, Inc. portfolio of DOCSIS 3.1 test solutions - hardware and software to generate and analyze signals up to 192 MHz bandwidth, as shown in Figure 1. These solutions can be used to test transmitters, re- ceivers and components against the new requirements set forth in the DOCSIS 3.1 specification. Figure 1.

Introduction Over the years, the DOCSIS standard evolved to meet the needs of cable operators and their subscribers. Emerging applications like HDTV video streaming around the home and in-room gam- ing, is driving demand for multi-gigabit data rates. The need for increased bandwidth led to the latest standard revision - DOCSIS 3.1. DOCSIS 3.1 provides a way for cable operators to increase capac- ity and speed, with up to 50 percent more data throughput over the same spectrum than DOCSIS 3.0, and the ability to deliver 2.5 Gbps in the upstream and 10 Gbps in the downstream on an existing hybrid fiber-coaxial (HFC) network. Its efficient spectrum use enables a significant decrease in the cost per bit for data delivery. This provides cable operators a competitive advantage over satellite and wireless providers in the hotly contested battle for today's bandwidth-hungry broadband data subscribers. 03 | Keysight | Quickly Validate Designs for DOCSIS 3.1 Compliance - Application Brief Key issues faced by R&D engineers Signal Generation (192 MHz bandwidth)
