English abstract:
With the development of atomic force microscopes that allow higher scan speeds, the need for data
acquisition systems sDAQd that are capable of handling the increased amounts of data in real time
arises. We have developed a low cost data acquisition and scan control system around a
commercially available DAQ board in a WINDOWS environment. By minimizing the involvement of
the processor in the data transfer using direct memory access, and generation of the scan signals
synchronously with the data acquisition, we were able to record 30 frames per second with a pixel
resolution of 1503150 pixels and 14 bit per channel.
