Abstract
A frequency synthesizeroutputs a periodic signal r(t) at a frequency detuned by a predetermined frequency Δf [Hz] from a frequency of 1/integer of a frequency of a reference clock signal f0 synchronized with a signal to be measured ws. A first sampler unitsamples the signal to be measured ws at a timing of the trigger signal CLK. A second sampler unitsamples an I signal I(t) at the timing of the trigger signal CLK. A phase shifteroutputs a Q signal Q(t) obtained by shifting a phase of the reference clock signal f0 by 90°. A third sampler unitsamples the Q signal at the timing of the trigger signal CLK. A correction value calculation unitcalculates a correction value Δt(n) based on sampling data I(n) and Q(n) and a set value t(n) of a sampling time.
