Design and Development of a Nanoscale Multi Probe System Using Open   Source SPM Controller and GXSM Software: A Tool of Nanotechnology
  We report our design, development, installation and troubleshooting of an open source Gnome X Scanning Microscopy (GXSM) software package for controlling and processing of modern Scanning Probe Microscopy (SPM) system as a development tool of Nanotechnology. GXSM is a full featured analysis tool for the characterization of nanomaterials with different controlling tools like Atomic Force Microscopy (AFM), Scanning Tunneling Spectroscopy (STS), scanning tunneling microscopy (STM), Nanoindentation and etc.,. This developed package tool consists of Digital Signal Processing (DSP) and image processing system of SPM. A digital signal processor (DSP) subsystem runs the feedback loop, generates the scanning signals and acquires the data during SPM measurements. With installed SR-Hwl plug-in this developed package was tested in no hardware mode.
