High Speed Subsystem

A Revolutionary Subsystem Approach for High-Speed Bus Test Requirements Providing High Throughput, Practical Programming, and Optimized Long-Term Logistics Costs…

The Teradyne High Speed Subsystem (HSSub) addresses requirements that are common to most recent designs including buses with increasingly fast data rates, the need for real-time interaction between the ATE and the UUT, and the need to test multiple buses concurrently. HSSub provides fast and flexible instrumentation integrated into a self-contained subsystem to address escalating digital speed and complexity. Within seconds, the HSSub Runtime Defined Instruments are configured to address the unique requirements of a specific UUT. The HSSub is designed for integration into existing or future large-scale test systems with the ease of a single instrument. Alternately, the HSSub may be used in a standalone role either as a bench-top tester or the nucleus for a newly designed test system.

The HSSub is designed as a commercial solution for Defense and Aerospace test that provides a more economical approach than the applications-specific approaches of the past. Lacking appropriate instrumentation for high-speed buses, test departments have been forced to use bus-specific laboratory instruments or fully custom ITA-based circuitry. Over time, these techniques tend to be very expensive due to low throughput, inefficient programming, lack of documentation and applications support, and difficulty in providing long-term logistics support.
