Abstract: An NMR Soft pulse Excitation Unit (SEU) with simplicity, economy as well as high performance has been developed.In addition, problems associated to assembling the main parts of the system are discussed in detail.The SEU operates successfully in conjunction with an MSL-300 NMR spectrometer and has been tested for the excitation of 1H in frequency of about 300MHz.

Key words: Soft pulse excitation unit, Selective excitation
