Abstract:
1. An oscillation device compensating a set value of an output frequency based on a detection result of ambient temperature, said oscillation device comprising: a first quartz-crystal oscillator structured by providing first electrodes on a quartz-crystal piece; a second quartz-crystal oscillator structured by providing second electrodes on a quartz-crystal piece; a first oscillation circuit and a second oscillation circuit connected to said first quartz-crystal oscillator and said second quartz-crystal oscillator, respectively; a frequency difference detecting unit determining, when an oscillation frequency of said first oscillation circuit is set to f a compensation value obtaining unit obtaining a frequency compensation value of f wherein the value corresponding to the difference value between the value corresponding to the difference between f wherein an output of said oscillation device is structured to be generated by utilizing an output of said first oscillation circuit; and wherein the set value of the output frequency is structured to be compensated based on the frequency compensation value determined by said compensation value obtaining unit.
