Integration of the RHK R9 to an Omicron VT-AFM

Application Note: Integration of the RHK R9 to an Omicron VT-AFM With the purchase of our Omicron VT-AFM (model XA) in 2007 we decided that we will equip the microscope with the RHK SPM 100 control and the RHK PLLPro2 NC-AFM electronics. In 2015 we upgraded our RHK control system to the new, fully digital R9 due to the fact that in most of our research projects, we need the improved performance of the R9, especially the computer-controlled spectroscopy measurements and frequency modulation techniques. In the following we will first detail the modifications done to our VT-AFM, then we will describe how we integrated the system to the RHK R9 and finally we will present the performance of the final system by means of a thermal noise analysis and a demonstration of the obtained imaging quality.
