Abstract:
1. An oscillator for outputting f 1 as an oscillation output by treating a differential signal corresponding to a difference between an oscillation output f 1 of a first oscillator circuit and an oscillation output f 2 of a second oscillator circuit as a temperature detection value, the oscillator outputting a control signal to suppress an influence caused by a temperature characteristic of f 1 based on the differential signal, the oscillator comprising: a storage unit that stores a parameter to output the control signal; a signal processing unit connected to a first signal path and a second signal path to retrieve the respective f a first connecting end and a second connecting end to be connected to an external computer; and a switching unit switches between a first state and a second state, the first state being a state where the first connecting end and the second connecting end are connected to the storage unit for access from the external computer to the storage unit, the second state being a state where the first connecting end and the second connecting end are connected to the first signal path and the second signal path such that the respective f
