Aquison™ Data Acquisition Platform

Actual Size is 4.0" x 6.0"

The Acquison platform is a real time system used to acquire data from sensors and perform real time control or processing.

The system brings together several hardware disciplines onto one PC board. It incorporates multi-channel 16-bit serial A/D converter, high performance FPGA with 50,000 gates, popular full speed EZ USB microcontroller, and support for many expansion capabilities.

The Acquison platform can serve a variety of applications, ranging from data acquisition with a PDA or host PC, to remote embedded internet data collection and control systems.

Designed to support new product development, the system helps you focus on your own rocket science design additions, rather than reinventing the many Acquison platform features.

Expansion daughtercards may be developed to accommodate specific component or processing needs you may have, such as sensor interfaces, alternate A/D converters, DSP, etc. The Acquison can serve as a base platform to support your product development needs.
