Keysight / Agilent / HP U3051C BusXpert Micro SATA Analyzer

The Keysight U3051C BusXpert Micro SATA Analyzer is a portable protocol analysis tool for debugging and testing Micro SATA and SAS devices. It captures and decodes SATA I, II, and III traffic at 1.5 Gbps, 3.0 Gbps, and 6 Gbps, delivering deep protocol insights, error detection, and real-time performance metrics. Engineers can configure the analyzer with 1 or 2 ports, buffer depths from 2 GB to 18 GB, and dual uplink options

PCIe x4 at 550 MB/s or Gigabit Ethernet at 70 MB/s - to match deployment requirements.
