Abstract:

The design of a pulsed field gradient unit for uses on NMR spectrometers is discussed. The main features of the present design are simplicity, high pe
rformance and economy. This unit is capable of generating arbitrary waveforms with only two external trigger lines. It is convenient to integrate this unit into
different types of NMR spectrometers.

Key words: NMR, Pulsed field gradient, waveform generator, FPGA
