DESCRIPTION

The PCI 228 was designed in the framework of isochronous acquisitions with the PCI 102.

Thanks to the use of leading technologies, this board features outstanding analog characteristics:

  • Analog section fully isolated from the logic section, which allows a very good signal-noise ratio.
  • Use of software-programmable-gain measurement amplifiers (1, 2, 4, 8).
  • 16-bit ADS per channel at 200KHz and 5ppm/°C reference for stable and accurate measurements.
  • A perfect isochronism and time-and-date stamping thanks to the PCI 102 concepts.

The PCI 228 can also be accessed via the PCI bus with 32-bit exchanges thus allowing high speed transfers for real-time applications.
