Accurate Data Capture with PCIe Analyzers
The Keysight U4301B PCI Express (PCIe) analyzer combines accurate probing technology with flexible hardware architecture. This PCIe 3.0 analyzer uses Keysight’s unique Equalization Snoop Probe (ESP) technology, allowing you to match the algorithm to the type of channel the protocol analyzer is monitoring. This technology ensures that the captured data is as accurate as possible.
Hardware
- Supports 2.5 GT/s (Gen1), 5.0 GT/s (Gen2) and 8.0 GT/s (Gen3) speeds
- x1 through x16 link width support
- 8 GB capture for x1 to x8 bidirectional, up to 16 GB capture for x16 bidirectional
- CEM slot, M.2 (M-key), and SFF-8639 PCIe interposers; PCIe Gen3 midbus probe, flying leads
Data viewing and navigation
- Packet viewer with flexible coloring, color by packet type or direction
- Lane view with packet highlighting to show the actual data on the bus (header, payload?)
- Simple packet filter, quick search and auto compute
- Correlation across all views, clicking in one view quickly navigates you to the same point in time in another view
Analysis tools
- LTSSM overview with equalization analysis helps verify the link training process and identify reasons for failure
- Traffic overview with detailed traffic pattern analysis and graphing
- Performance analysis with utilization, throughput, response time and latency measures (including flow control analysis)
- Transaction decode of PCIe, NVMe and AHCI with data analysis with data overview
Simple-to use, powerful state-based triggering
- Simple-to-use filters and triggers
- Advanced triggering for complex scenario analysis (ex. missing completion)
