• Powerful and flexible capability: Basic measurements are built in, and you can add packages as needed.
• Consistent results: Use in design to simulate and analyze signals, in the lab to characterize prototypes, and in production and support to operate equipment remotely.

In addition to the data acquisition and basic measurement capabilities the N1010A FlexDCA software provides, Keysight offers a large selection of software tools with powerful capabilities:

• N1010100A, research and development package for the FlexDCA sampling oscilloscope software: This package is intended for R&D engineers who want to characterize their designs and gain more insight into why a signal deviates from the expected performance.
• N1010200A, manufacturing package for the FlexDCA sampling oscilloscope software: This package focuses on cost of test in optical transceiver manufacturing applications with capabilities such as FlexEye that enhance measurement flexibility. It includes measurements such as TDECQ.
• N1010300A, signal integrity package for the FlexDCA sampling oscilloscope software: This package adds powerful tools to measure impedances, transfer characteristics, and S-parameter calculations to the basic TDR / TDT measurements.

Compute Express Link (CXL) is an industry supported, high-speed interconnect standard that enables coherent memory access between a host and end-point device. CXL leverages the dependability and performance of the PCI Express® physical layer and uses a flexible processor port to auto-negotiation whether the link will communicate using the standard PCIe protocol or the supported alternate CXL transaction protocol. CXL defines three sub-protocols CXL.io, CXL.mem, and CXL.cache that are used for initialization and link-up, and to facilitate the coherent sharing of memory between computing devices.

P5561CXLA CXL 1.1 / 2.0 Protocol Exerciser Software supports protocol traffic generation for all CXL 1.1 and 2.0 supported speeds and lane widths from x1 to x16. The CXL exerciser can emulate a root port or endpoint, generate FLIT traffic and includes built-in LTSSM test cases, error insertion, and a protocol checker. The P5561CXLA software is used with the P5573A/74A/75A series of protocol exerciser hardware which is designed to be easy to setup, connect, and quickly configured to bring up the CXL link and check LTSSM and protocol functionality.

• Supports CXL 1.1 and 2.0 specifications for data rates up to 32 GT/s
• Generate traffic on link widths of x1, x2, x4, x8, x16
• Emulate a CXL host or any of the three CXL endpoint device types
• Generate CXL.io, CXL.mem, and CXL.cache transaction sub-protocols
• Protocol error checking
• Automated Link training with speed change skip and bypass support
• Support for Alternate Protocol
• Over 100 predefined LTSSM test cases
• Error insertion
• Combined Analyzer and Exerciser Software GUI
• Full featured API supporting Python, C++, and C#

The P5576PSWA PCIe 6.0 Protocol Analyzer Traffic Analysis Software combined with the P5570A Protocol Analyzer with its integrated, single add-in-card design, brings unparalleled test tools to the world of protocol traffic debugging for PCIe 6.0. The vast feature sets of the analyzer provide deep functionality for validation and debugging issues, while also providing improved data exchange between device and host. This not only completes all demands of PCIe 6.0 protocol testing in one simple and user-friendly interface but also reduces time and energy on rooting out and validating root causes.

LTSSM Overview

• Proper Link Training is critical to solid PCIe performance, and it is often the source of many issues.
• Physical differences in channels and products are manifested at the protocol layer via the LTSSM.
• The LTSSM Overview allows visual progression through the LTSSM and a decode of which state both the Upstream and Downstream ports are in at a given moment. The LTSSM Overview is a powerful tool for debugging one of the most difficult and complex aspects of PCIe protocol.

Lane View

• Lane view provides a view of exactly what data is appearing on which lane of the PCIe link.
• With a mouse over a particular lane shows what packet types individual bytes are associated with. Thus, in a single simple view, a comprehensive understanding of the protocol makeup is given.

Transaction Decode

• The Transaction Decode tab provides a detailed view of how individual packets are organized into a transaction. The initial packet operation, acknowledgement, and completion are condensed into a single line in the Transaction Decode view, which can easily be expanded to see each packet atomically. The transaction based view can be much more intuitive to look at than the chronological order of packets provided in the Packet view, and gives a deeper understanding of the protocol.

Powerful Triggering and Filtering

• The most difficult bugs to solve are intermittent with no obvious cause. Finding the root of these troublesome issues often involves setting up long capture times. But capturing lots of data is not helpful if it cannot effectively be analyzed. Scrolling through trace captures looking for specific issues that are obscured by retraining events and other protocol ‘storms’ is an ineffective use of time.
• Finely tuned triggering and filtering settings to be able to capture most interesting traffic. This avoids massive capture windows that scoop up unwanted data which slows down the analysis process both in porting the data to a PC for viewing as well as needlessly obscuring critical protocol events. The Keysight P5576A PCIe 6.0 Protocol Analyzer Traffic Analysis Software was designed with this use case in mind. As such, it provides both Simple and Advanced triggering modes. Simple triggers are provided that are quick to be applied and customized. Advanced Triggers can be configured to apply a chain of If/Then logic steps to the trigger. In this way specific protocol events can be captured easily, even if they occur only after a complex series of previous events that may span a long time period.
• To extend this capability even further filtering can be applied to ignore certain traffic events to extend the capture window without clogging up the capture log with unneeded data.

The P5577PSWA PCIe 6.0 Protocol Exerciser Traffic Analysis Software combined with the P5573A Protocol Exerciser, with its integrated, single add-in-card design, brings unparalleled test tools to the world of protocol traffic debugging for PCIe 6.0. The vast feature sets of the exerciser provides deep functionality for configuring traffic setup, while also providing improved data exchange with the analyzer. This not only completes all demands of PCIe 6.0 protocol testing in one simple and user friendly interface but also enables more focus on designing and automating unique test cases while saving amounts of time and energy.
