  • Instrument Overview
    • Teradyne PXI Express HSSub instruments address the challenge of recent and upcoming test requirements including increasing speed, data volume, protocol and processing complexity, as well as low-latency UUT interaction
    • Instruments are configured and accessed via application-specific HSSub Apps that are authored by Teradyne, end users, or third-party developers
    • HSSub Instruments employ a Three-Tier architecture to perform the critical operations associated with old, new, custom, and standard digital interfaces
    • The time-critical operations take place within the instruments, independent of the central computer and Windows operating system
    • Multiple autonomous instruments, independent of central resources, support concurrent asynchronous UUT interfacesHSSub-Three-Tier-Architecture.PNG

    There is a wide range of HSSub instrumentation that provide tier1, tier 2, or combined functionality.

  • Reconfigurable Core Instruments
    • HSSub Core Instruments combine a Test Defined FPGA for low-level I/O Bus Processing (tier 1)HSSub 5010 and a multi-core processor with RTOS for Upper Level Protocol Real-Time Processing (tier 2) into a single open-architecture instrument
    • Two Core Instruments share identical internal structure:
      • The Serial Core Instrument supports up to 16 bidirectional channels at up to 3.125 Gb/s
      • The LVDS Core Instrument supports up to 72 LVDS differential pairs at up to 800 Mb/s
    • A TPS-invoked HSSub App loads processor-based procedures and Test Defined FPGA code, configuring the instrument in seconds
    • The processor and FPGA have large, high-speed local memories
    • Each instrument can run autonomously, independent of the Windows-based computer (tier 3), and multiple instruments can run concurrently
    • Direct paths between tiers 1 & 2 provide the lowest possible latency for time-critical protocols
    • For more information on Core Instruments:
  • Real-Time Processing Modules
    • The Real-Time Processor Module provides the same multi-core processor with RTOS capabilityHSSub 5020 as the Core Instruments
    • The module typically provides Real-Time Processing (tier 2) support in conjunction with other  HSSub instruments handling low-level I/O Bus Processing (tier 1)
    • HSSub Apps associate the processor modules with other instruments and configures them within seconds
    • Each Real-Time Processor Module and associated instruments can run autonomously, independent of the Windows-based computer (tier 3), and multiple groups of instruments can run concurrently

  • Reconfigurable IO Expansion Instruments
    • HSSub Reconfigurable IO Expansion Instruments provide low-level I/O Bus ProcessingHSSub-Reconfigurable-IO-Expansion-Instruments.png (tier 1) with large, high-performance Test Defined FPGAs
    • Reconfigurable instruments can be repurposed from one TPS to another to meet a wide range of bus requirements; standard-compliant as well as variations from standards, well-specified as well as those with evolving needs
    • A TPS-invoked HSSub App loads the Test Defined FPGA code, configuring the instrument in seconds
    • Each instrument contains large, high-speed local memory directly accessible to the FPGA
    • IO Expansion Instruments may be controlled directly by the tier 3 Windows computer for applications that do not require real-time support
    • IO Expansion Instruments may be associated with a Real-Time Processor in a Core Instrument, or a standalone Real-Time Processor Module
    • Each IO Expansion Instrument has unique capabilities to support applications with various I/O signal requirements, channel counts, and parallel or serial buses

    • The HSSub dedicated bus instruments provide the highest density and performance available in single-slot, 3U PXI Express form factor
    • The most widely used standard serial buses are best served by instruments based on bus-specific dedicated chipsets with provide a broad range of configurability that is controlled by HSSub Apps
    • HSSub-6090/6091 Ethernet instruments:
      • Support copper-based or optical Ethernet
      • Share data with Tier 2 functionality if real-time Upper Level Protocol processing is required
    • The HSSub-6120 FireWire Instrument implements the AS5643 Upper Level Protocol in an onboard Tier 2 Real-Time Processor
    • The HSSub-8030 provides common PC buses in an instrument as a more supportable approach than servicing the UUT directly from a computer
