    Electrical Modes
    For engineers and researchers that need accurate data on conductance, sample resistance,
    and other electrical and topographic properties, Park offers a range of electrical scanning modes.

QuickStep™ SCM

QuickStep™ to make faster SCM data acquisition

In order to improve the signal-to-noise ratio conventional SCM adopts very slow scan speeds as a means of giving the detector enough time to collect the data. QuickStep™ SCM differs from conventional methodology of slow continuous movement. Here, XY scanner stops at each pixel point to record the data and then makes a fast and rapid hop to the next measurement points. This effectively speeds up the scan rate while maintaining the same signal sensitivity of the measurements by conventional SCM at slow scan speeds.
