Gxsm is a full featured and modern scanning probe microscopy (SPM) software. It can be used for powerful multidimensional image/data processing, analysis and visualization. Connected to an instrument, it is operating many different flavors of SPM, e.g. scanning tunneling microscopy (STM) and atomic force microscopy (AFM) or, in general, two-dimensional multi channel data acquisition systems. The Gxsm core can handle different data types, e.g. integer and floating point numbers. An easily extendable plug-in architecture provides many image analysis and manipulation functions. A digital signal processor (DSP) subsystem runs the feedback loop, generates the scan signals and acquires the data. The programmable Gxsm vector probe engine can perform any thinkable spectroscopy and manipulation task, such as scanning tunneling spectroscopy (STS) and tip formation. Due to the support for a new DSP hardware (SoftdB SR-MK2&A810) new developments like multi channel feedback mixing and adaptive infinite response for the tunneling current had been implemented. The Gxsm software is released under the GNU general public license (GPL) and can be obtained free of charge via internet from http://gxsm.sf.net.
