  • Measurement & Data Analysis Software Included

The new digital SXM Control System incorporates advances in state-of-the-art electronics and latest software algorithms to fulfill the needs of today’s and future challenges in scanning probe microscopy. Features of the new SXM Controller include low noise, large detection bandwidth, high resolution 24 bit D/A and A/D converters, easy software and hardware handling, accessible and simple file format and a basic data analysis software package. In combination with 32 bit data handling, the outstanding fast 22 bit D/A converter for Z-regulation sets a new benchmark for SPM controllers as it overcomes the classic restrictions (resolution and voltage stability) of existing 16 or 20 bit solutions. The controller comes with an integrated phase locked loop (PLL) for piezoelectric cantilever based non-contact AFM (NC-AFM) and lock-in amplifiers for high-resolution spectroscopy (e.g. dI/dU, dI2/dU²).

Software functionalities such as continuous monitoring and observation of simultaneously measured signals in an Oscilloscope window, and quantitative FFT spectrum analysis makes this a user friendly and efficient solution. The extensive software package for scanning probe spectroscopy and atom manipulation enables a variety of experiments ranging from standard imaging and spectroscopy to user defined spectroscopy and manipulation experiments. A graphical user interface for implementation of macros for custom tailored experiments ensures experimental flexibility and expandability to cope with future experimental work flows and challenges.
