NI PXIe-7902 Ethernet Test Solution

The Ethernet Test Instruments integrates up to twelve independent Ethernet interfaces into the LabVIEW environment using the PXIe-7902 card. The FPGA core is designed for test and verification applications and is available with LabVIEW support or Windows C API and can be integrated into LabVIEW TestStand. The Test Instrument can be operated in two modes: In interface mode, the user can control the Ethernet interfaces in real time via software. Test mode is conducted via scripted operations where the user specifies all facets of the transaction including header info, payload, packet type, and cadence/timing of operations before handing off execution to the hardware. During both modes, all incoming and outgoing packets are time stamped, recorded, and logged for user review.

Features

  • Fully-programmable Ethernet traffic patterns
  • Hardware offload of performance critical traffic flows
    • Script engine defines transaction mix, hardware executes script at wire speed
    • Hardware transmit and receive logs with time-stamping
  • DRAM transmit and receive packet buffers DMA channels from DRAM to host
  • Windows C or LabVIEW API and example designs
  • Independent operation of each Ethernet interface
  • Error-injection, error-detection, and checksum corruption
  • User-definable MAC addresses
  • Designed to IEEE 802.3-2012 specification

Benefits

  • Build, control, and analyze data streams directly in LabVIEW
  • Records all transactions with hardware time-stamp accuracy
  • Supports established or user-defined protocols for your custom application
  • Real-time statistics gathering
  • Complete FPGA design with FPGA-based offload of protocol; No FPGA design needed by user
  • Reduce development time focused on software test applications instead of test hardware development
