Claim 28:
29. A computer-readable medium storing a computer program comprising instructions that when executed by a computer system of a scanning probe microscope including at least one bending beam having at least one measuring tip, wherein the at least one bending beam is configured to be operated in at least one closed control loop, cause the computer system to perform:
receiving at least one controlled variable of the at least one control loop;
processing a control error of the at least one control loop using a bit depth that is greater than the bit depth of the controlled variable; and
providing a manipulated variable of the at least one control loop;
wherein the scanning probe microscope operates the at least one bending beam in at least two of the following operating modes: a contact mode, a non-contact mode, an intermittent mode, and a step-in mode.
