Accurate knowledge of a gradient magnetic field waveform is important for measurement of diffusion coefficients in NMR. Diffusion coefficients are determined from the decay between the MR signal affected and the one not affected by the gradient pulses. Therefore the waveform of the gradients is essential from the point of view of the accuracy. Short ramp times, amplitude of generated gradients and symmetry of positive and negative levels (i.e. integral of two pulses with the same amplitude and inverse polarity is zero) are desirable.
