Abstract
A circuit apparatus includes an oscillation control circuit configured to control oscillation of a resonator, a measurement unit configured to measure information corresponding to a frequency of an oscillation signal output from the oscillation control circuit, and an interface, and is configured such that, when a first signal that determines a measurement period received from outside, the measurement unit measures the information corresponding to the frequency of the oscillation signal output during the measurement period, and the interface outputs a measurement result of the information corresponding to the frequency.
