Protocol Analyzers

PCI Express

PCI Express (PCIe) has become the leading interconnect technology to succeed the Peripheral Connect Interface (PCI) architecture.The PCI Express(PCIe) architecture retains the PCI usage model and software interfaces for investment protection and smooth development migration. The technology is aimed at multiple market segments in the computing and communication industries, and supports chip-to-chip, board-to-board and adapter solutions. PCI Express 4.0 currently runs at 16GT/s or 16GBps per lane in each direction, providing a total bandwidth of 64GBps in a 16-lane configuration which is the largest size in use.

Summit Z416 Protocol Exerciser   The Summit Z416 is a PCIe 4.0 protocol traffic generation test tool used for critical test and verification intended to assist engineers in developing and improving the reliability of their systems. The Summit Z416 can emulate PCI Express 4.0 root complexes or device endpoints, allowing new designs to be tested against corner case issues.
Summit T3-16 Analyzer   The Summit T3-16 Protocol Analyzer captures, decodes and displays PCIe 3.0 protocol rates for x1, x2, x4, x8, x16 lane widths
Summit T3-8 Analyzer   The Summit T3-16 Protocol Analyzer captures, decodes and displays PCIe 3.0 protocol rates for x1, x2, x4, x8 lane widths
Summit T34 Analyzer   The Summit T34 Protocol Analyzer captures, decodes and displays PCIe 3.0 protocol traffic data rates for x1, x2, x4 lane widths
Summit T28 Analyzer   The Summit T28 Protocol Analyzer captures, decodes and displays PCIe 2.5GT/s and 5GT/s data rates for x1, x2, x4, x8 lane widths
Summit T24 Analyzer   The Teledyne LeCroy Summit T24 PCI Express analyzer is for customers developing PCIe 1.0 or 2.0 x4 lane width server, workstation, desktop, graphics, storage, and network card applications.
Summit Z3-16 Exerciser with SMBus Support   The Summit Z3-16 with SMBus Support is a critical test and verification tool intended to assist engineers in developing and improving the reliability of their systems. The exerciser can emulate PCI Express root complexes or device endpoints, allowing new designs to be tested against corner case issues.In addition, it can emulate SMBus traffic as a master or slave.
Protocol Test Card   Protocol Test Card officially certified by the PCI SIG for PCIe 2.0 compliance testing
Compliance Testing   The UNH NVMe conformance tests run on the Teledyne LeCroy Protocol analyzer and exerciser. These tools support the necessary NVMe emulation capabilities to perform these tests.
PXP-100B Test Platform   The Teledyne LeCroy PXP-100B Test Platform provides a convenient means for testing PCIe cards with a self-contained portable and powered passive backplane. The PXP-100B provides power required for both cards under test, and an interposer can be used for connection to a protocol analyzer.

Teledyne LeCroy offers five PCI Express protocol analyzer platforms (Summit™ T3-16, Summit T3-8, Summit T34, Summit T28, and Summit T24). The Summit T3-16 Analyzer is Teledyne LeCroy's fifth generation architecture and highest performance platform. It provides full bidirectional support of x16, x8, x4, x2, and x1 at data rates up to 8 GT/s. With 8 GB of trace memory, it offers enough capacity for analyzing and recording extensive PCI Express data streams. Supporting lane widths up to x8 at 8 GT/s, the Summit T3-8 offers the same powerful features and as an option allows for two T3-8 systems to be connected together to achieve a full x16 lanes at 8 GT/s. Ideal for embedded systems monitoring and analysis is the Summit T28, smaller and a more cost effective PCI Express protocol analyzer for x8 lanes at 5GT/s. While all of the Summit analyzers support PCIe storage protocols like NVM Express, SATA Express and SCSI Express, the Summit T34 is addresses PCIe storage analysis with a small, portable form factor, x4 lane width and a deep recording buffer of 32 GB of memory. For portability and ease-of-use the Summit T24 protocol analyzer offers analysis support for x1-x4 lanes at 2.5/5GT/s. The Summit T24 is Teledyne LeCroy's most optimized and low cost analyzer for analysis of PCIe 2.0 add-in-boards.

All Summit analyzer platforms use the PCI Express iPASS connector for probing. Teledyne LeCroy features the largest selection of PCIe based interposers and probing solutions. Teledyne LeCroy's PCI Express Protocol Analyzer solutions employ non-intrusive and transparent probing technologies thereby allowing fully unaltered data pass-through. In addition, it leverages the intuitive and powerful Teledyne LeCroy’s Trace expert software system, embedding a deep understanding of the PCI Express protocol hierarchy and intricacies and presents this knowledge to the user in a colorful, intuitive and easy to use graphical display, allowing users to quickly capture and validate PCI Express product designs. These analyzers enable IP, semiconductor, switch, software and system developers as well as add-on card vendors to quickly identify protocol violations and ultimately reduce development and debugging time.

Developers can use Teledyne LeCroy's PCI Express Protocol solutions to easily capture and decode PCI Express Transaction Layer Packets (TLPs), Data Link Layer Packets (DLLPs), and low-level link traffic, including Training Sequences and Skip Ordered-sets. Some of the errors detected include: 8b/10b errors, such as invalid symbols and incorrect running disparity; CRC errors; idle data errors; and EDB (End-of-Packet Bad) errors. They also provide a detailed display of split transactions, correlating requests transmitted from one PCI Express endpoint with completions received from the endpoint at the opposite end of the link.

Teledyne LeCroy is well known for its technical leadership. Customers have come to depend on Teledyne LeCroy supporting protocols while they are early in development when these tools are essential.


The PCI Express exercisers can generate PCI Express transactions, observe behavior, and perform both stress testing and compliance testing. The Summit Z3-16 supports the new Specification 3.0 ("Gen3") data rates of 8 GT/s across up to 16 lanes. The Summit Z3-16 Exerciser supports up to x8 lane widths at data rates of 2.5 GT/s. As complete solutions, both the Summit T3-16 and Summit Z3-16, or PETracer/Trainer™ systems give you the unique ability to record (capture) live traffic, modify the traffic, and then playback the exact data stream, or "script," using the exerciser.

Protocol Test Card

Teledyne LeCroy offers an integrated and automated compliance testing system, including Protocol Test Cards, approved by the PCI-SIG® as a standard tool for compliance testing for developers working with both the PCIe 2.0 and 3.0 specifications. In addition, the Summit Z3-16 exerciser is the only approved tool to run the UNH-IOLs NVM Express Conformance Tests. These tests are required for the NVM Express Integrators test.
