Parallel Sampling A/D Board Provides 14-Bit Resolution

The PCI-417 parallel-sampling, PCI-based board employs an independent A/D converter on each of its 32 channels to provide sampling rates up to 80 kHz per channel with 14-bit resolution. Aggregate sampling rate is up to 5.12 MB/s. Selectable for each channel, input voltage ranges are ±5V or ±10V full scale. An on-board analog-to-digital memory system is included to prevent sample losses when streaming large sample blocks, and the board's bus controller acts as a temporary DMA PCI bus. Output is via two streaming 16-bit D/A channels with an output voltage range of ±2.5V at a maximum current of 5 mA and with a maximum settling time of 1 µs full scale. Operating system support is via Windows 98/NT/2000/XP with DLL Visual C++ software and ActiveX control support also available. The board comes with a 16k x 32 FIFO (PCI-417N1) or a 128k x 32 FIFO (PCI-417N2) priced at $2,295 and $2,595 each, respectively. Visual C++ source code, PC-CDROMS, is available for $395.
