BusXpert Micro PCIe Analyzer

Available Downloads

The BusXpert Micro PCI Express® (PCIe®) analyzer is SerialTek’s second 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 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 have long been hallmarks of SerialTek storage protocol products but now is available in a small form factor.

The PCIe Micro analyzer is a compact and portable solution weighing 4.5 lbs; but it offers the features, functions and capabilities that are similar to the original PCIe Analyzer offered by SerialTek, making it a well-suited test not only for lab environments but also for field and support engineers.

It employs advanced technologies such as the industry’s first hardware accelerated gigabit Ethernet, pre-indexed and compressed trace data, multiple analysis processors, and instant display of the captured data. The analyzer provides support for up to 72 GBs of capture buffer, 36 GBs upstream and 36 GBs downstream. Even the entry model that comes installed with 9 GBs of trace buffer has a deeper capture buffer than most competing analyzers. The BusXpert features easy to use triggering, pre/post-filtering, textual search and sequence search, and many different displays of captured PCI Express traffic.

Three probing options are supported including x1 and x4 slot interposer capability of supporting 5.0 GT/s and 8.0 GT/s data rates. This interposer permits PCIe traffic between a host system and a PCIe device or card to be monitored, captured and analyzed. In addition, a M.2 interposer is available for M.2 socket 2 or M.2 socket 3 devices. The interposer when used with the BusXpert PCIe analyzer permits PCIe protocol traffic between a host system and a M.2/NGFF connector on a solid state device (SSD) to be monitored, captured and analyzed. This board support bus lane widths of x1, x2 as well as x4. The interposer also supports SSD lengths for 42mm, 60mm, 80mm and 110mm. Serialtek also offers a SFF-8639 interposer. This interface is designed to be used to analyze PCIe traffic between a host backplane and dual ported SSDs. The interposer supports both 2.5” and 3” sized SSDs.

In addition to supporting the Gen2 and Gen3 PCIe standards, the analyzer will support the newer Advanced Host Controller Interface (AHCI) protocol, SCSI over PCI Express (SOP) and Non-Volatile Memory Express (NVMe) technologies. The software provides for a new and powerful waveform “eye” display. This unique capability, founded typically on oscilloscopes, allows for digital signals to be easily observed in a graphic form. The feature permits users to take control over sample rates and display resolution. Eye diagrams are used as an aid in obtaining the optimal signal integrity by graphically showing the effects of varying calibration settings on the received serial data. These diagrams may be saved as either a graphical image or a file containing all the data and options needed to reconstruct the eye diagram. Now PCI Express engineers have not only the ability to observe the upper layer protocol transactions but also the lower physical layer information in a single compact, portable unit.

All SerialTek tools are designed to accurately capture, decode and analyze high-speed storage communication traffic. Our solutions help engineers verify, locate and resolve issues with their product designs. This shortens development and testing cycles, improves product quality and reduces time to market.
