NI PXIe-6594 Ethernet Test Solution

Available on National Instruments PXIe-6594 high-speed serial card, the Ethernet Test Solution is a flexible tool for test environments that allows the user to record up to 8 simultaneous ports of ethernet and/ or send up to 8 simultaneous channels of user-defined data. The tool is based around the widely utilized PCAPNG file format for file I/O that allows the user to leverage a wealth of open-source tools and guides to view, analyze, and create data sets.

PCAPNG encapsulation is handled entirely within the FPGA which allows high throughput, precise timestamps, and consistent performance. Captured data may be buffered within the card’s DDR (8GB) allowing high performance capture performance without a high-performance PXIe chassis or controller. For high-performance systems, the stream to disk feature allows Terabyte+ captures of sustained bandwidths of 20Gbps+.

Data transmission is also based around the PCAPNG file format which allows the user to playback previously recorded files or send custom-made data sets. Conversion from the PCAPNG format to ethernet streams takes place entirely in hardware which allows both high performance throughput and precise timing. Similar to recording modes, the user can select between a DDR buffer mode and stream from disk mode. DDR buffer mode allows high-performance data transmission without a high-performance chassis or controller. When properly configured, a high-performance chassis can stream from disk and send Terabyte+ data sets at 20Gbps+.

Features

  • Completely customizable Ethernet packets and data transmission patterns
  • Hardware timestamping (5ns resolution) synchronized across all 8 ports
  • Coordinate data transmission across all 8 ports within a single PCAPNG file
  • Stream to/from disk or DDR buffer
  • Windows C or LabVIEW™ API. Example designs provided
  • Statistical eye diagrams for signal integrity measurements
  • Statistics and error collection/monitoring

Benefits

  • View, analyze, or create Ethernet Traffic using PCAPNG natively in LabVIEW™ or with a wide variety of open source tools
  • Capture or generate large Terabyte+ data sets
  • Complete FPGA design with FPGA-based offload of protocol. No FPGA design needed by user
  • Reduce development time by focusing on software test applications instead of test hardware development
  • Lower total cost of test development and test system operation
