| description | The present disclosure is directed to a method of manufacturing an oscillator. The oscillator includes a resonator element, an oscillation circuit which outputs an oscillation signal by oscillating the resonator element, and a temperature compensation circuit which compensates for temperature characteristics of a frequency of the oscillation signal in a desired temperature range. The method includes a first temperature compensation adjustment step in which the frequency is measured at multiple temperatures, and first temperature compensation data is calculated based on a relationship between temperature and the frequency. The method also includes performing a second temperature compensation adjustment step in which, after the first temperature compensation adjustment step, the frequency that is obtained by performing temperature compensation by the temperature compensation circuit based on the first temperature compensation data is measured at multiple temperatures, and second temperature compensation data is calculated based on a relationship between temperature and the frequency. |
