Claim 14:
15. A scanning probe microscope comprising:
at least one bending beam configured to be operated in at least two of the following operating modes: a contact mode, a non-contact mode, an intermittent mode, and a step-in mode, wherein the at least one bending beam comprises at least one measuring tip, and the at least one bending beam is configured to be operated in at least one closed control loop;
at least one first interface designed to receive at least one controlled variable of the at least one control loop;
at least one programmable logic circuit designed to process 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
at least one second interface designed to provide a manipulated variable of the at least one control loop.
