Glossary terms about Amplitude

The size of the oscillation in the cantilever during dynamic modes (tapping and non-contact modes).

Cantilever tuning - only for tapping and non-contact modes
This is almost always an automated process in the AFM software, and all the operator has to input is the frequency range to scan over and the target amplitude of the cantilever. 
In addition to topographic imaging, many modern AFMs have the capability to image via a number of different mechanisms including frictional force, phase contrast, amplitude, adhesion and elasticity. 
Laser alignment on cantilever
The laser alignment will help determine the signal to noise ratio, the sensitivity of the cantilever deflection or amplitude and ultimately the quality of any data acquired using the AFM. 
Set point - Tapping mode
In this mode of operation, set-point refers to the amplitude of oscillation of the cantilever at which the tip taps the sample surface. 
Tapping mode
The cantilever is oscillated at or near its resonance frequency with an amplitude ranging from 20nm to 100nm.
