摘要

A reference signal generation device includes a reception unit that receives a reference signal, a first oscillator that includes an atomic oscillator, a first phase comparator that compares a signal output from the first oscillator and the reference signal in phase, a second oscillator that generates a signal to be output outwardly, and a second phase comparator that compares the signal output from the first oscillator and a signal output from the second oscillator in phase. The first oscillator includes a sweeping-result output unit that outputs a sweeping result signal corresponding to a resonance signal obtained by performing frequency sweeping in the first oscillator. The reference signal generation device further includes a determination section that determines a failure state based on the sweeping result signal and at least one of a phase comparison signal of the first phase comparator and a phase comparison signal of the second phase comparator.
