Abstract
An oscillator uses a differential signal corresponding to a difference between an oscillation output f1 of a first oscillator circuit and an oscillation output f2 of a second oscillator circuit as a temperature detection value, and outputs a control signal for reducing an influence caused by a temperature characteristic of the oscillation output f1 based on the differential signal. The oscillator includes a switching unit configured to alternately switch between a first state where a first connecting terminal and a second connecting terminal are connected to a storage unit for access of an external computer to the storage unit, and a second state where the first connecting terminal and the second connecting terminal are respectively connected to a first signal path and a second signal path via a frequency reduction unit such that the output signals from the frequency reduction unit are extracted to an external frequency measuring unit.
