The PCI 238 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).
• A BUTTERWORTH or BESSEL 8th order filter, whose exceptional characteristics in terms of cut-Off, ripple, phase and amplitude gap between channels
• 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 238 can also be accessed via the PCI bus with 32-bit exchanges thus allowing high speed transfers for real-time applications.
