Testing multiple serial protocols with a single instrument

A comprehensive protocol test platform from Tektronix Inc. allows engineers to analyze, stimulate, stress and characterize high-speed serial links — with support for speeds up to 10Gb/s.

Engineers working with high-speed serial protocols need to perform a number of tests, including interoperability and compatibility testing, performance optimization and stress testing.

With the TPI4000 protocol analyzer series one instrument can be used to perform multiple test functions and to look at a variety of protocols such as Ethernet, Fibre Channel, Common Public Radio Interface (CPRI), and Serial Front Panel Data Port (FPDP).

The TPI4000 series consists of two models. The TPI4202 is a portable unit with a built-in monitor and keyboard and supports up to 8 ports. The TPI4208 is a 4U rack-mount unit that supports up to 32 ports. Each model is highly configurable with options to support different data rates, to support different protocols, and to support different applications.

The TPI4000 can be configured by the user to be any combination of protocol analyzer, traffic generator, system stress tester, or BER (bit error rate) tester.  It can support any combination of protocols simultaneously and can be reconfigured by the user to support different protocols. Multiple protocol support allows users to troubleshoot system-level problems.

It has a built with a user-editable database that allows customers to define custom protocols using the optional Protocol Editor tool which the TPI4000 suitable for applications such as defense electronics that add proprietary and confidential extensions to existing protocols.

High-speed serial protocols supported by the TPI4000 Series include Fibre Channel (FICON, AS1760, ASM, FC-AE-1553, others), Ethernet (iSCSI, FCoE, TCP/IP, IPv6, iFCP, AFDX, ARINC664, TTE, others), Serial Front Panel Data Port (Serial FPDP), Serial Attached SCSI (SAS), Serial ATA (SATA), Common Public Radio Interface (CPRI) and Serial RapidIO (SRIO).

The TPI4202 portable unit is available now and the TPI4208 4U rack-mount unit will be available starting in the second half of 2012.
