This document describes several data acquisition and motion control systems from PCT including a Texas Instruments TMS320F28335-based system, an Altera FPGA-based MiniDAQ system, a multi-channel spectral source controller for fluorescence microscopy and other applications, a 16-axis expandable data acquisition and motion control system, a 16-axis differential input incremental encoder interface, a 4-axis high power motion drive system, and an 8-channel differential input incremental encoder interface. Refer to the data briefs for more details on each system.
