Introduction

The Keysight Technologies, Inc. high speed U4301B PCI Express 3.0 analyzer module is a protocol analyzer supporting all PCI Express® applications from Gen1 through Gen3, at speeds, including 2.5 GT/s (Gen1) and 5.0 GT/s (Gen2) through PCIe 8 GT/s (Gen3), and with link widths from x1 to x16. The U4301B analyzer captures and decodes PCI Express data and displays it in a packet viewer window.

The U4301B analyzer is a blade that installs into an AXIe two-slot M9502A or five-slot M9505A.

Probing is provided by the U4321A solid-slot interposer probe, U4324A flying lead solder down probe, or the U4322A mid-bus probe based on Keysight’s equalization snoop probe (ESP) technology.

Gain insight into the equalization process and all of the state transitions with views that can be customized to meet your requirements. The analyzer ’s LTSSM overview can pinpoint specific training sequence issues through easy-to-interpret analysis results.

Keysight’s transactional decoder includes a transactional viewer that allows the designer to select transactional queues and performance information from the analyzer’s NVMe transaction overview pane. This organizes the transactions by direction or by queue to follow the data flow across the interface, with one-click control. Individual PRP (Physical Region Page) lists contain all of the key information of the NVMe queues, allowing designers to quickly review and validate the data flows over the PCIe connections.

The performance analysis package includes the real data throughput calculations, with response-time measurement of the PCIe data flow. It allows designers to measure and understand throughput performance, PCIe response times, and other operational measurements that provide the insight needed to optimize device performance.

Complementary PCIe stimulus and response testing of the PCIe system is accomplished with the addition of the U4305B PCIe Gen3 exerciser.
