Keysight Technologies, Inc. (Santa Rosa, CA) has introduced the U4301B PCIe(R) protocol analyzer for engineers developing PCIe Gen3 systems. The U4301B supports all PCIe speeds from 2.5 GT/s (Gen1) through 8 GT/s (Gen3) and link widths from x1 through x16. The analyzer comes standard with analysis tools to validate PCIe LTSSM (link training and status state machine) processes, as well as NVM (non-volatile memory) Express and AHCI (advanced host controller interface) transactional protocol operations. New interposers support the latest storage devices that use SFF-8639 and M.2 connectors. The U4301B PCIe analysis module works in an AXIe chassis.
