Because the PLLPro can measure the DC offset of the detector signal, the user can switch to Contact Mode measurement through the control software at any time. Also now possible are simultaneous imaging of the normal and (if provided by the preamp) lateral force average signals with measurements from any non-contact AFM mode.
To make use of this flexibility, user scripts can monitor the normal and lateral force averages and react to them, for instance by nulling them out after driving a process parameter, such as probe-sample bias with a DAC. |
