Abstract : A method and apparatus for determining anomalies in the frequency- or admittance-temperature characteristic of a piezoelectric crystal resonator by inserting a variable capacitance network in series with the crystal and electronically sweeping the value of the capacitance network by a control voltage applied thereto while the temperature remains constant and noting any abrupt change in the resonance frequency characteristic.
