Serial Data

PCI Express

PCI Express (PCIe) has become the leading interconnect technology to succeed the Peripheral Connect Interface (PCI) architecture. Teledyne LeCroy released the first PCIe protocol analyzer in February of 2003. Teledyne LeCroy also offers oscilloscope solution on their SDA 13000 analyzer designed to perform compliance testing at the phyical layer.

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 T3-8 Protocol Analyzer captures, decodes and displays PCIe 3.0 protocol rates for x1, x2, x4, x8 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.
Protocol Test Card   The Teledyne LeCroy Protocol Test Card (PTC) is a multimodal test board used for checking adherence to the protocol-oriented sections of the PCI Express 2.0 specification.
Interposers and Probes   The Summit product family includes a wide variety of Interposer systems, designed to reliably capture serial data traffic while minimizing perturbations in the serial data stream. Probes include interposers, which are designed to capture data traffic crossing the PCI Express card connector interface, and MidBus probes, which are designed to capture traffic flowing within a PCB.
PCIe Decode   The PCIEbus D option provides comprehensive PCI Express Gen1.x protocol decode for most efficient debug.
PCI Express 3.0 Test Suite   Requirements for serial data testing unique to PCI Express Gen3 place new demands on the traditional physical layer test tools. Not only does the specification mandate that the receiver tester be protocol aware, but certain other characteristics of PCIe Gen3, such as dynamic equalization, essentially require combined physical/protocol layer test capabilities for validation and debug. Only Teledyne LeCroy has the comprehensive set of physical layer, protocol layer, and network analysis tools for complete PCIe Gen3 transmitter, receiver, and channel testing.
ProtoSync   The ProtoSync option further leverages the supported Teledyne LeCroy decode annotation options (PCIEbus D, USB3bus D, USB2bus D, USB2 HSICbus D, SATAbus D, SASbus D, FCbus D) installed on the oscilloscope.
QPHY-PCIe   The Teledyne LeCroy QPHY-PCIe Test Solution provides automated control for Teledyne LeCroy oscilloscopes for performing the entire transmitter physical layer tests as described by the Card Electro-mechanical specification Rev 1.1 and 2.0
QPHY-PCIe3   Teledyne LeCroy QPHY-PCIe3 Test Solution provides automated control for Teledyne LeCroy oscilloscopes for performing transmitter physical layer tests as described by the PCI Express Base Specification Revision 3.0 Version 0.9 and the Card Electromechanical Specification Revision 3.0 Version 0.7.
PCI Express Analysis Solutions
Protocol Analysis

Teledyne LeCroy introduced their PCI Express Analyzer technology in the spring of 2003 for Gen1 applications. Since that time the protocol analyzer has become an essential tool in many industry leader’s labs that have successfully brought PCI Express based products to market. Working with these companies has helped produce the right user interface and analysis features for PCI Express Protocol debugging and performance enhancement.

Teledyne LeCroy offers three protocol analyzer product lines (Summit™ , PETracer™ ML, Edge T1-4). The Summit T2-16 Analyzer is Teledyne LeCroy’s fourth generation architecture and highest performance platform. It provides full bidirectional support of x16, x8, x4, x2, and x1 at data rates up to 5 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 x4 at 2.5 GT/s, the PETracer ML Analyzer has 2 GB of trace memory and offers outstanding performance for Gen1 PCI Express applications. For portability and ease-of-use the Edge T1-4 Analyzer offers Gen1 analysis and low cost form factor for add-in-boards applications

Teledyne LeCroy's PCI Express Protocol Analyzer solutions employ high impedance, non-intrusive probing technology thereby allowing fully unaltered data pass-through. In addition, it leverages the intuitive and powerful Teledyne LeCroy 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.


The PCI Express exercisers assist with generating PCI Express transactions, observing behavior, and performing both stress testing and compliance testing. The Summit Z2-16 supports the new Specification 2.0 (“Gen2”) data rates of 5 GT/s across up to 16 lanes. The PETrainer ML Exerciser supports up to x4 lane widths at data rates of 2.5 GT/s. As complete solutions, both the Summit T2-16 and Summit Z2-16, 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 the Protocol Test Card, approved by the PCI-SIG® as a standard tool for compliance testing for developers working with the new Gen2 specification.

PCI Express Physical Layer Testing

The Teledyne LeCroy SDA 6020 Analyzer and PCI Express Compliance and Development software offer a complete test and debug. QPHY-PCIe provides a highly automated solution for PCI Express 1.1.

The Teledyne LeCroy SDA 13000 can perform PCI Express 2.0 Compliance Test and Debug. It can acquire and quickly analyze PCI Express 2.0 signals using the SigTest(PCI-SIG Compliance Utility). The SDA 13000 has the memory depth to acquire all required 1 million UI in a single acquisition. Waveforms can be saved in the TRC format and quickly analyzed by SigTest. Built into the standard SDA tools are the 14 Masks, 3 PLLs and 2 Jitter Filters specified by PCI-SIG.
