Zusammenfassung:	In a frequency converter (28), a transmission signal having a first frequency component and a second frequency component is multiplied by a local signal, and the transmission signal is frequency-converted. In the power amplifier (30), the frequency-converted transmission signal is amplified. A branching circuit (18) generates a first transmission signal and a second transmission signal from the amplified transmission signal. The controller (25) sets frequency sets (F0, F1, F2) suitable for the two irradiation frequencies (RF1, RF2) for the transmission unit (22). 一种NMR测定装置，在频率转换器(28)中，将具有第1频率成分和第2频率成分的发送信号乘以本地信号，从而发送信号被进行频率转换。在功率放大器(30)中，频率转换后的发送信号被放大。分波电路(18)从放大后的发送信号生成第1发送信号和第2发送信号。控制器(25)对发送部(22)设定适合于2个照射频率(RF1、RF2)的频率集(F0、F 1、F2)。
