Electronic controller 8EG-3000 is designed to control SPM or confocal microscope performance. Controller provides data acquisition from system sensors and external devices, applies control voltage to scanners piezoelectric actuators, all obtained information is transferring to PC work station for visualization and processing. Control signal is transferring from PC to controller for adjust all system parameters.One of the most important parts of the 8EG-3000 controller is closed loop feedback system. Based on a high quality 20-bit TDC (Time to Digital Converter) to measure displacement capacitance sensors. Any available system signal can be used for SPM feedback. Controller is capable to operate 6 channels with feed back simultaneously, which allows to scan by tip and by sample both.

8EG-3000 SPM controller contains 2-channel lock-in amplifier to provide resonant SPM techniques, for example non contact spm mode. Lock in amplifier includes high stable voltage generator based on digital frequency synthesizer. High speed data processing implemented, using programmable logic(PLIS), allows to perform high quality lock in performance up to 1.5MHz band.

8EG-3000 has malty channel (up to 12) stepping motor control with micro step option for rough adjustments of scanning head (stage).

Controller has external analog inputs and outputs for external equipment connections, sync inputs and outputs. Connection with PC work station is provided via USB interface. Universal software Nspec, designed for using with 8EG-3000 has wide range of possibilities for data processing, which allows to implement set of modern SPM techniques. Nspec is capable of running under different operation systems.
