6U Data-Acquisition Board Integrates High-Speed DSP

Supported by the accuracy of Texas Instruments' floating-point TMS3206711 DSP, the 6U DT9841 Fulcrum II series data-acquisition measurement system targets high-end processing measurements. The board incorporates eight simultaneous channels of 24-bit sigma-delta analog-to-digital (a-d) conversion at 100 ksamples/s. Two simultaneous channels of 24-bit sigma-delta digital-to-analog (d-a) conversion are also included. Each a-d and d-a subsystem has its own high-speed pathway in and out of memory, allowing each to execute real-time measurements without processor intervention. The system's 24 lines of digital I/O are configured as eight inputs, eight outputs, and eight programmable digital I/O. Up to three counter timers can be included, each with up/down capability. USB 2.0 support speeds communications with the host and backs next-generation peripherals that require processing speeds up to 480 Mbits/s. The embedded C6711 DSP is software-programmable and can be used in standalone or system test operations. Because it comes with 2 Mbytes of flash memory, the DSP does not require host intervention. Two board configurations are available: The DT9841-128 features 128 Mbytes of SDRAM, and the DT9841-64/2 has 64 Mbytes of SDRAM and 2 Mbytes of flash memory. Both run on Windows 2000 and XP. Available now, the DT9841 costs $3995 each.
