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.


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.
