Abstract:
1. A measurement apparatus that measures a signal under measurement, comprising: a first oscillation circuit that receives one pulse of the signal under measurement and begins oscillating according to the pulse of the signal under measurement to output a first oscillated signal: a second oscillation circuit that receives one pulse of a reference signal and begins oscillating according to the pulse of the reference signal to output a second oscillated signal having a period that is different from a period of the first oscillated signal; and a first sampling section that samples the first oscillated signal according to a pulse of the second oscillated signal, wherein the first oscillation circuit includes: the second oscillation circuit includes: the first control section or the second control section counts a number of pulses that pass through the first loop line or the second loop line, respectively, and, when the resulting count value reaches a predetermined value, stops the output of the first oscillated signal or the second oscillated signal, respectively.
