%X Arbitrary Waveform Generator(AWG) plays an important role in general purpose signal generators.It is widely used in physics,electronics and computer area.In this paper,a non-PC dependent AWG designed specifically for use in low-field MRI is proposed.The performance of the AWG is tested with MRI experiment.Potential problems in the current design are discussed.
