Electrical characterization of a tuning fork crystal oscillator using dual-phase lock-in technique.
We performed an electrical characterization of a tuning fork crystal oscillator using a dual-phase lock-in amplifier. Direct measurements of the complex admittance allowed us to extract all four values of the equivalent circuit model components of the tuning fork crystal oscillator.
