High-Speed High-Resolution Digital Piezo Controller

N-Dimension Technologies' digital piezo controllers represent the most advanced motion-control and nano- positioning controllers available today. The state-of-the- art system is based on 32-bit DSP's, and can control three-dimensional motion/displacement with sub- nanometer accuracy Features   24-bit resolution digital feedback control with   basic 80K/s sample rate. High-speed USB interface. Standard PID control with other customer options. Support for various sensors such as strain gauges, capacitance and LVDT sensors. Additional analog input and output for user convenience. 4 to 6 orders polynomial linearization. Internal wave-form generator. Parallel high-speed I/O interface options. Technical Data
