Goal of the quantitative mechanics measurement regime is to evaluate local mechanical properties using off-resonance tapping technique for feedback and evaluating the individual force-distance curves obtained during this process.

To make it work, a periodic excitation in the range of hundreds of nanometers has to be added to the cantilever motion, which allows the probe to snap in contact, measure a force-distance dependence in the contact, leave it providing an adhesion value and then come to contact again. This can be done using a shaker piezo or by combining the generator 1 output with 20-bit z-piezo signal.
