| Abstract | The report presents a compact Python-based automatic control system for frequency-response and Q-factor measurement of the piezoelectric quartz tuning fork, widely utilized as the shear-force sensing probe in scanning probe microscopy (SPM). The frequency sweep of the driving signal and the signal readout of the QTF are controlled automatically by a Python-based software, developed in this research. The software provides a GUI front panel for users to choose the number of data points for the frequency sweep, the frequency range and the amplitude of the driving signal. Additionally, the frequency response curve and the Q-factor calculation can be displayed after the end of the frequency sweep. Such an automatic Q-factor measuring system will assist the design of efficient probes for SPM systems. |
