  • Applications
    • Test of Defense & Aerospace assemblies with optical high-speed buses, which are becoming increasingly prevalent in critical applications:
      • New weapon systems such as F-35 that use a fiber optic backbone to interconnect a distributed array of smart sensors, transducers, displays, and processing units
      • Platform upgrades such as the F/A-18E/F Distributed Targeting System (DTS) that bring fiber optic technology to legacy platforms
      • Test of assemblies from planes, ships, and land-based vehicles that benefit from the improved speed, noise immunity and reliability of optical interconnections
    • Parametric test of optical transmitters and receivers to avoid No-Fault-Fond results at assembly test, and to ensure interoperability of units with the weapon system
    • Test of assemblies with buses such as Fibre Channel, Ethernet, Serial RapidIO, Serial FPDP, PCI Express, Xilinx Aurora, and Altera SerialLite at speeds of 100Mb/s to 10Gb/s
    • Concurrent test of multiple buses on one UUT, and parallel test of multiple UUTs
    • Test of new and future assemblies with increasing port count and complex bus protocols using the latest generation of instrumentation, such as that of the Teradyne High Speed Subsystem (HSSub) or AIT product lines
  • Advantages & Benefits
    • VERTA key features provide specific advantages over alternative approaches:
      • VERTA Optical Power Management provides accurate, wide-range control and measurement to ensure that multiple assemblies will interoperate properly in the weapon system 
      • VERTA Crosspoint Matrix Switching interconnects many UUT ports and multiple UUT Assemblies to allow concurrent and parallel Link Integrity testing
      • VERTA Link Integrity Test ensures the ability to reliably communicate between assemblies
      • VERTA flexibility supports the widest range of port counts resulting in the appropriate instrument sizing. Independence of speed and bus protocol minimizes the overall quantity of hardware.
      • VERTA optimizes long-term supportability through proven Teradyne design, manufacturing, and support processes, tailored for Defense & Aerospace products with a track record of over 40 years
    • These VERTA advantages produce the following benefits:
      • VERTA Optical Power Management and Link Integrity Tests minimize weapon system maintenance costs by preventing no-Fault-Found test results that allow faulty assemblies to circulate in the repair cycle
      • VERTA Concurrent and Parallel test capabilities reduce overall factory test times and increase test equipment utilization to optimize capital return on investment
      • VERTA flexibility eliminates the need for multiple optical instruments to minimize acquisition, integration, training, programming, and support costs
      • VERTA long-term supportability advantages minimize long-term logistics costs
  • Optical Power Management
    • The optical power received at a UUT port input must be within a relatively narrow range in order to ensure reliable link operation
      • The output power of each UUT port transmitter must be within a specific range
      • Each UUT port receiver must be able to operate over a specific range of power
      • The input and output specifications must take into account variations in attenuation that will take place in the weapon system optical cabling and connectors
      • All of the above optical characteristics can vary over time
      • Some UUTs must compensate for large variations in attenuation over long or complex optical interconnections within the weapon system. In these cases, a wide range of optical power measurement and control in the test equipment is required.
    • The Verta-3020 Switching and Power Management Module provides power control and measurement in addition to switching
      • Each of the 16 ports consists of an input channel and an output channel for connection to the UUT
      • The output channel of each port converts copper signals from the VERTA Crosspoint Matrix to an optical source, followed by a programmable attenuator and power meter.
      • The input channel of each port measures the optical signal and converts it to copper for connection to the VERTA Matrix
      • The broad input and output power range is sufficient for most applications.
    • The Verta-5010 Wide-Range Power Management Module extends the optical power range to a 35 dB range. See VERTA I/O Module Options for more information.
  • Link Integrity Tests
    • Link Integrity Test
      • Large quantities of data can be exchanged between the ATE and UUT in order to ensure error-free operation in the weapon system.
      • VERTA Optical Power Management can be used to perform large data transfers at worst case power conditions.
      • If the UUT is designed to participate in Bit Error Rate Test (BERT), VERTA and HSSub are the ideal ATE combination.
      • The self-contained processing capability of the HSSub bus instruments make them the ideal complement to VERTA for comprehensive Link Integrity Test.
  • Concurrent and Parallel Tests
    • Concurrent Test
      • As the number of optical UUT I/O ports increases, it is often necessary or advantageous to test the ports simultaneously
      • Concurrency is required if the results on one port depend on simultaneous activity on another port
      • Testing UUT ports simultaneously may significantly decrease overall test time
      • VERTA crosspoint switching is non-blocking, allowing the interconnection of any number of concurrent ATE instrument and UUT ports without conflict
      • Local processing within HSSub instruments allows test of multiple ports simultaneously, and additional independent instruments allows the total port count to scale with demand
    • Parallel Test
      • Testing multiple UUTs in parallel is often advantageous to decrease test time, increasing ATE throughput
      • As with Concurrent Test, VERTA non-blocking switching coupled with HSSub local processing and autonomous operation are ideal for parallel test
  • Flexibility
    • VERTA addresses evolving Defense & Aerospace optical requirements while avoiding technical or logistical obsolescence through:
      • Support for a wide number of UUT I/O ports, bus types, and speeds
      • Integration with current and future high-speed serial bus instrumentation
      • Accommodation for emerging requirements and test methodology
    • A VERTA instrument is contained within a single housing provided by one of the VERTA Foundation Options
      • Each of the Foundations provide power, cooling, LXI interface, and a full crosspoint switch that is independent of bus protocol and speed
      • The Foundation houses I/O Modules that interface with the bus test instruments and the UUT, allowing the VERTA instrument to provide switching and Optical Power Management
    • The broad range of VERTA I/O Module Options provide configuration flexibility that accommodates the required port count and power management range
      • All VERTA I/O Modules operate independent of bus protocol and speed
      • The Verta-3020 Optical Power and Switch Module provides 16 ports with crosspoint switching, output power control, and input power measurement for interfacing with the UUT
      • The Verta-3010 Multi-Protocol Switch Module provides 16 ports with switching and nominal power levels, typically for connection to ATE bus instrument ports, which do not require power management
      • The Verta-5010 Wide-Range Optical Power Module provides 8 ports with high dynamic power range capability over input measurement and output control in conjunction with a Verta-3020 ports
  • Comprehensive Support
    • VERTA supportability is built on over 40 years of Teradyne experience in Defense and Aerospace test, with a reputation for delivering products with superior technical and logistic services that extend over long product lifecycles
    • VERTA is designed for long-term support
      • VERTA instruments are exposed to rigorous shock and environmental testing to ensure that they are mission-ready for shipboard or mobile environments
      • VERTA product longevity begins with strict component selection and lifecycle monitoring processes implemented within Teradyne’s experienced Design and Supply Line Management Organizations
      • Conservative design, high-density packaging, and product testing maximize Mean Time Between Failure (MTBF)
      • Comprehensive diagnostic self-test software and modular design minimize Mean Time to Repair (MTTR)
    • Equipment intended for commercial products, such as optical data transmission and server/storage equipment, has been used in Mil/Aero ATE
      • Commercial and Mil/Aero requirements are rapidly diverging, resulting in widespread obsolescence of formerly dual-use support equipment
      • Equipment targeting commercial applications is impractical because the buses they target have lifetimes of a few years rather than decades
      • Defense and Aerospace ATE needs the more stable solution that VERTA provides; multiple bus protocols and speeds, simultaneous connections, optical power management and long-term support
      • Product longevity continues over the years based on Teradyne’s commitment, organization and resources, backed up by a proven history
    • VERTA flexibility and extensibility allows it to address future requirements better than conventional equipment, minimizing or eliminating the need for additional hardware
  • VERTA Foundation Options
    • VERTA instrumentation is contained in a single Foundation which consist of a self-contained chassis, crosspoint matrix, power supplies, cooling, and LXI interface circuitry
      • Foundations are available in a range of sizes from a basic 4-slot, 64-port model to a large 7-slot, 112-port model
      • All Foundations provide the same LXI interface that simplifies system integration and a Windows-based IVI-C or IVI.NET driver for a unified programming environment
    • Each Foundation contains a multi-gigabit semiconductor crosspoint switching matrix, and slots for the various VERTA I/O Modules that together form a Physical Layer Switch
      • Within the Foundation, the semiconductor crosspoint switch provides the programmable interconnection capability, and exposes a wired (copper) multi-gigabit interface to the VERTA I/O modules
      • The Foundation switch is indifferent to bus protocol and speed, eliminating the need for multiple bus and speed-specific units
      • The Foundation switch allows any port of a VERTA I/O Module to be cabled to a high-speed serial ATE instrument, such as a Teradyne HSSub instrument, or to any I/O port of a UUT
      • The matrix can connect any port input to any port output
      • An input can be connected to multiple outputs to stimulate redundant circuitry, or for concurrent measurements
      • Unlimited simultaneous connections support multiple concurrently operating buses of various types and speed
    • The single, unified VERTA Foundation reduces the costs of acquisition, integration, training, programming, and support
  • VERTA I/O Module Options
    • The Verta-3010 Multi-Protocol Switch Module provides full-flexibility switching and nominal optical power levels
      • The module uses standard SFP/SFP+ (Small Form-factor Pluggable) transceiver to convert from the electrical signals of the Foundation switch to optical I/O.
      • The fixed-power Verta-3010 is typically used for optical connections to the bus test instruments because these connections do not affect UUT operation.
      • Verta-3010 can be used for UUT connections if Optical Power Management is not required
      • If UUT ports require a copper connection, appropriate SFP transceivers are available, such as for 100BASE-T and 1000BASE-T Ethernet VERTA-Tab-10-1.PNG
    • The Verta-3020 Optical Power and Switch Module provides power control and measurement in addition to switching
      • In place of the fixed-power SFP transceiver approach, each power-managed port employs high-performance discrete optical components
      • The output channel converts copper signals from the VERTA Crosspoint Matrix to an optical source, followed by a programmable attenuator and power meter
      • The input channel measures the optical signal and converts it to copper for the VERTA MatrixVERTA-Tab-10-2.PNG
    • The Verta-5010 Wide-Range Power Module supports special circumstances that demand a very wide range of optical power
      • Some UUTs must operate over a wide range within the weapon system to compensate for varying attenuation associated with long or complex optical interconnections, and some UUTs simply require testing at the power extremes
      • Verta-5010 has 8 bidirectional ports, each with an input channel and an output channel
      • This module provides an optical-to-optical capability with a 35 dB power range for measurement or output control
      • The 8 ports are typically optically connected to 8 ports of a Verta-3020 Optical Power and Switch Module for the full flexibility of VERTA matrix controlVERTA-Tab-10-3.PNG
