Abstract
An apparatus and method of automatically determining an operating frequency of a scanning probe microscope such as an atomic force microscope (AFM) is shown. The operating frequency is not selected based on a peak of the amplitude response of the probe when swept over a range of frequencies; rather, the operating frequency is selected using only peak data corresponding to a TIDPS curve.
