A high-frequency generator circuit comprises a signal generating circuit, a delay unit, a selector, a synthesizer circuit, and a controller. The signal generating circuit generates a signal having the same frequency as an output signal. The delay unit includes a plurality of delay circuits, and delays the signal generated by the signal generating circuit. The selector selects an output signal of the delay circuits. The synthesizer circuit synthesizes the signal selected by the selector, and outputs the output signal. The controller controls the selector based on data for setting a waveform of the output signal and a control signal for setting at least amplitude, phase and frequency of the output signal.
