ABSTRACT:
A crystal oscillator for measuring crystal impedance (CI) easily and accurately of various crystal units having an oscillating frequency in a wide band and various CI-values in a broad rage. A DC input voltage is measured, representing CI of a crystal unit, in a crystal oscillator, wherein an integrating circuit is provided in an output section providing a frequency oscillated from the crystal unit as an output, and one or more AGC amplifiers having an amplification rate proportional to a DC input voltage is provided between the crystal unit and the integrating circuit.
