Zusammenfassung:	In a magnetic resonance measurement apparatus such as an NMR measurement apparatus, a plurality of transmission signals are combined to generate a digital combined signal. The digital combined signal is converted into an analog combined signal by a D/A converter (48). The signal includes, for example, a first pulse (124) of a rectangular shape and a second pulse (130) of a mountain shape. During measurement, an operation of a dynamic variable attenuator (52) is changed immediately after the first pulse. With this process, the second pulse is suppressed, and a suppressed second pulse is generated. With this structure, the amplitudes of the pulses can be dynamically varied after the plurality of transmission signals are combined.
