PROBLEM TO BE SOLVED: To provide a time/frequency measuring device, capable of carrying out measurement by automatically determining whether a high-precision frequency signal fout generated by a reference frequency generating device is in a applicable state at a measuring side of a time/frequency measuring device, based on frequency accuracy information from the reference frequency generating device. SOLUTION: The time/frequency measuring device detects that frequency deviation information of the high-precision frequency signal outputted by an outside reference oscillator is within a prescribed frequency deviation as a target, and carries out measurement of a frequency or time of a signal to be measured by applying the high-precision frequency signal, based on the detection. |
