PCI-416-G2A Datel Ultra-Performance Analog Input PCI Computer Board

The Datel PCI-416 Ultra-Performance Analog Input Boards for PCI Computers consists of several advanced-performance, data acquisition boards based on the 32-bit PCI bus architecture. With an emphasis on continuous, non-stop, high-speed streaming of A/D samples to host memory or disk, the system has been optimized for a wide range of signal-processing and data-recording applications. In very long "baseline" studies or high-speed transient analysis, the PCI-416 can collect huge amounts of "seamless" digitized data to host memory. Exploiting a unique "banked" FIFO architecture, the PCI-416 moves two A/D words in each 32-bit PCI transfer. The FIFO memory (8k samples deep) serves to decouple the precise timing of the A/D converter from the block bursts of the PCI bus.

The PCI-416's optional analog front ends utilize DATEL's lownoise, wide-bandwidth sampling A/D converters. All models exhibit excellent harmonic distortion and perform well in DSP/FFT applications. Software for Windows 95, NT, DOS, Hyperception and LabVIEW implements a menu-driven, "no-programming", fast data recording and display system to memory or disk. Several different "pluggable" analog options offer up to 16 input channels in single-ended or differential configurations, multiple input ranges, sampling rates to 10MHz, 12/14/16-bit A/D resolutions, and various simultaneous sampling configurations (1 A/D per channel) up to 16 channels. The simultaneous feature is intended for parallel sampling applications that cannot tolerate phase skew introduced by the A/D system. These include sonar or acoustic sensor arrays, cross-channel computation, multiple carrier demodulation, interferometry, multi-channel spectrometers, and highly concurrent system testing. High quality, wide-bandwidth, low-noise A/D's and analog components are used. The design is ideal as an array processor "front end" or for DSP/FFT (Digital Signal Processing/Fast Fourier Transform) usage.
