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.

The Teledyne LeCroy Summit T34 PCI Express protocol analyzer is designed for PCIe storage, add-in card and embedded application developers. It supports x1 to x4 lane widths with the capability of expanding to x8 with two boxes connected together, and deep buffer memory that is expandable from 4GB to 64GB ideal for storage analysis, the Summit T34 provides unmatched capability and flexibility for developers and users of advanced PCI Express products. Teledyne LeCroy has been the leader in NVM Express and SATA Express protocol analysis since 2010. This storage analyzer incorporates all of these powerful legacy features and adds the latest in storage queuing performance analysis.

Portable and Compact

The Summit T34's small dimensions (209 x 40 x302 mm) and at a light weight of 3 lbs it is clearly the most portable compact PCI Express protocol analyzer in the market today.

PCIe 3.0 speeds

The Summit T34 supports PCI Express 3.0 Specification at data rates from 2.5 to 8 GT/s.

Deep Memory Buffer

With a flexible memory buffer that is expandable from 4GB to 64GB (expanded using a second unit), the Summit T34 provides a deep trace memory capture for developers debugging challenging storage issues.

Powerful Views

As with other Teledyne LeCroy PCI Express analyzers, the Summit T34 leverages the intuitive and powerful CATC Trace analysis software system, embedding a deep understanding of the PCI Express protocol hierarchy and intricacies. The colorful, intuitive and easy to use graphical display allows you to quickly capture and validate PCI Express product designs. The application display is highly configurable and can be modified to fit most users debugging styles. A customizable multi-state trigger makes it easy to discover protocol issues on the bus. Features such as multiple local/global timers and counters allow the user advanced control to create sophisticated trigger sequences.

PCI Express Storage

The portable Summit T34 protocol analyzer is designed to support multiple PCIe storage protocols such as SATA Express, NVMe and SCSI Express. The new storage related capabilities and new protocol analysis views optimized for PCIe storage development are currently supported across the product line and make these tools valuable to understanding data transmission from the PCI Express protocol layer up to the command layer.

Lane Swizzling

In addition to a full suite of advanced hardware and software features, the Summit T34 provides user-convenience and analysis features, such as support for "lane swizzling" which allows a board developer to lay out a Mid-Bus probe pad with lanes in non-standard order, simplifying the design of the board. Internally the Summit T34 maps the lanes back into their correct order and accurately displays the embedded bus traffic. Other software features include enhanced error checking for automatic identification of additional error types, more compact trace files that allow for faster analysis of trace data, and the choice of simplified or advanced modes for setting up trace recording options.

Bit Tracer

A new raw recording mode, Bit Tracer, allows bytes to be recorded as they come across the link, allowing debugging of PHY layer problems and combining the features of a logic analyzer format with a protocol analyzer format. The new auto sense link feature monitors negotiation between devices of different lane widths, and the bifurcated link support recombines multilink PCI Express operations that have been separated into narrower links.

Lan Support

The Summit T34 also supports Ethernet LAN port as a standard feature. By connecting over a LAN, engineers can operate the system remotely (e.g., install the client software on their desktop systems, and control an analyzer operating in a remote lab). Also, multiple engineers working collaboratively can time-share use of a single analyzer, reducing the need for an additional analyzer for each engineer, and increasing the cost effectiveness of the product.

Flexible Configurations

The Summit T34 is available in two configurations—that support either x1, x2, and x4,; or x1, x2, x4, and x8, if combined with a second Summit T34—to match user requirements with available budgets. The upward compatibility and 13 month warranty of the Summit T34 also provide investment protection for current Gen2 users who plan to upgrade to Gen3 devices in the future.


All Teledyne LeCroy PCI Express protocol analyzers employ high-impedance, non-intrusive probing technology, thereby allowing fully unaltered data pass-through.

Debug in any PCIe environment

By leveraging years of experience in protocol analysis tools for emerging markets, Teledyne LeCroy's PCI Express protocol analyzers blend sophisticated functionality with practical features to speed the development of PCI Express IP cores, semiconductors, graphics, servers, workstations, bridges, and switches.
