P5570A PCI Express Protocol Analyzer for PCIe 6.0

Data Sheets


The P5570A PCIe Protocol Analyzer enables deep protocol analysis of PCIe systems in a form factor that is easy to deploy on the lab bench and offers unparalleled signal integrity. The analyzer supports capture and decode for PCIe 1.0 through PCIe 6.0. When paired with the P5573A Protocol Exerciser, incredibly powerful PCIe validation solutions can be built.

Product Overview

The Keysight P5570A PCIe 6.0 Protocol Analyzer features an integrated interposer design which simplifies connection and offers improved signal integrity. By removing the need for a cumbersome external analyzer chassis, setup and versatility on the lab bench are greatly improved. Additionally, this simplified design yields superior signal integrity, ensuring that the analyzer has minimal impact on the channel between the products under test.

The P5570A supports decode of up to 64 GT/s signaling and lane widths of x4, x8 and x16. Users can utilize up to 16 GB trace depth memory aided by on-board compression which greatly expands the available capture time. The analyzer supports decode of the PHY Layer (TS1/TS2/Ordered sets, Link Layer (ACK,/NAK, sequencing numbers, replay, etc), and Transaction Layer (Memory, Config, and I/O Read and Writes operations, etc)

Trusted Signal Integrity

Debugging complicated interoperability issues between a PCIe Host and Device requires that any protocol analyzer interposer not disrupt the interactions between a Host and Device. The foundation of this in the P5570A is superb control of signal integrity with built in equalization and amplification that effectively removes the effects of the analyzer from the link. This provides the user with confidence that the traffic observed between the Host System and Endpoint are exactly as if the analyzer were not present.

Other analyzer designs that rely on a separate analyzer chassis often introduce physical and electrical complexities that can impact the channel. In some cases, these interposers inadvertently add channel impairments which can affect the system under test such that it cannot reliably negotiate to the highest mutually supported speeds and lane width. In other cases, an interposer may introduce retiming or redriving capability that can mask issues in the system under test by effectively improving the channel quality and enabling devices to successfully link up in configurations that could not be attainable without the analyzer present. Neither of these conditions is acceptable as they impede the ability of the test and validation engineer to gain a clear and accurate view of what is happening on the link.

The Keysight P5570A was designed deliberately to avoid these issues, to minimize channel impact and to provide the clearest and most accurate view of the traffic on the PCIe link. Thus, test and validation engineers can focus time and energy on solving protocol issues between the products under test, rather than questioning whether issues have been introduced or masked by their test equipment.

Convenient and Stable Form Factor

The single card design of the Keysight P5570A PCIe 6.0 Protocol Analyzer enables a convenient and fast setup on the lab bench. Often test configurations on the lab bench quickly become complicated, and mechanical stability of prototype devices is critical to ensure that early product samples are physically protected and that the mechanical connection between the analyzer and the products under test is solid and robust and not introducing any signal impairments due to lack of mechanical stability. The P5570A is provided with a bracket mount that enables secure attachment a server chassis. Additionally, attention has been given to providing mechanical security to add-in-card endpoints that are included in the test setup via an additional stability bracket.

Combined Exerciser and Analyzer Software

Both the Keysight PCIe 6.0 P5570A Protocol Analyzer and P5573A Exerciser can be driven by a single combined software interface which with provides enhanced Exerciser Functionality for configuring Traffic Setup and improved data exchange with the Analyzer.Via this thoughtfully designed interface, the user can configure all of the most important characteristics of the PCIe link such as lane width and link speed.

Use Case: Analyze Traffic between Root Complex and Endpoint

A common use case for the Keysight P5570A PCIe 6.0 Analyzer is to sit between a PCIe 6.0 capable root complex and a PCIe 6.0 endpoint. The analyzer will capture and decode PCIe signals between the root complex and the endpoint while also passing the signals between the devices through without interference.

The Keysight P5570A Analyzer uses an independent power supply, and passes power supplied from the Host System on to the Endpoint without interference.
