Abstract: The present application concerns an apparatus for data acquisition and control to be used in connection with a scanning probe system. This apparatus comprises positioning means (3), used to provide for a relative, lateral scan movement of a sample to be scanned and a probe of said scanning probe system, and interface means (1) for processing analog signals (z1, z2) generated by the probe, and for conversion of these analog signals into digital data signals (d1, d2). The apparatus further comprises a converter (4) for conversion of said digital data signals (d1, d2) into composite video signals, and a process controller (2) connected to the positioning means (3), interface means (1) and converter (4) for the control and management of the operation of the scanning probe system.
