BusXpert Micro II PCIe Analyzer

The BusXpert Micro II PCI Express® (PCIe®) analyzer is SerialTek’s third analyzer designed and optimized for equipment manufacturers that are developing storage products and solutions using PCI Express technology. With support for data rates of 2.5 GT/s, 5.0 GT/s (Gen 2) and 8.0 GT/s (Gen 3) and bus widths of x1, x2 and x4, the Micro II provides accurate capture, analysis and deep insight of PCIe traffic at all layers of the protocol stack. It offers the same ease-of-use, multiple display views, powerful triggering, and attractive price points that are the hallmarks of SerialTek storage protocol products, and adds the benefits of a small form factor and zero calibration.

The BusXpert supports up to 36GB of capture buffer, pre-indexed and compressed trace data, multiple analysis processors, and instant display of the captured data. The BusXpert also features easy-to-use triggering, pre-/post-capture filtering, textual search and sequence search, and many different displays of captured PCI Express traffic. It is available in a variety of configurations to fit specific requirements for buffer size, protocols, and budget.

This SerialTek analyzer supports the PCIe protocol, including all TLP, DLLP, and Ordered Sets, and the NVM Express™ (NVMe) protocol.
PCIe 3 is the latest standard and is fully supported by SpecXpert, as are revisions 1.0a, 1.1 and 2.0 of the specification.
