Family of data acquisition systems using USB 2.0

USB (Universal Serial Bus) is ideal to be used for devices that often have to be connected temporarily. This family of data acquisition sub-systems are used in laboratory environments where USB connectivity is also very practical.
The systems provide 2, 4 or 16 analog channels to be measured simultaneously. The channels can be configured for different sample rates, and different analog filter settings and offset. A special 50/60Hz suppression filter is provided.
These systems make use of an FPGAfor the logic around the A/D convertor, DSP, USB the D/A convertors.
