An NMR apparatus has a circuit adapted to improve the degree freedom of design and generate an excitation radiofrequency wave pulse suited for a sample to be measured. The radiofrequency wave transmission circuit includes a local oscillator, an IQ modulator having two mixers and two arbitrary waveform generators connected to the IQ modulator. Fourier inverse transform is applied to data inputted to the arbitrary waveform generators.
