The E-725 digital piezo controller is a compact, high-performance drive electronics for nanopositioning systems with up to three axes. High-power amplifiers permit dynamic scans even for piezo systems with large range or direct drive. State-of-the-art processor technology optimizes the operating parameters for improved linearity and tracking accuracy. High-resolution D/A converters provide for nanopositioning that deserves this name. With the E-725.3CM, PI for the first time offers a digital controller for the P-363 PicoCube™ , a fast precision scanner for atomic force microscopy. Optional interfaces and analog in- and outputs make it possible to process external sensor or control values.
