Abstract
A gradient amplifier for a nuclear magnetic resonance tomography apparatus has at least one control arrangement with a comparator and a controller and a control input for a digital control word, by means of which a current transmission function of the control arrangement can be selected from several predetermined transmission functions. A nuclear magnetic resonance tomography apparatus includes such a gradient amplifier, as well as a control word producing source for producing the digital control words. The gradient amplifier and the tomography apparatus can easily be adjusted to different controller characteristics, without the changeover requiring a manual calibration.
