Abstract: A device and system for generating a broadband excitation signal and corresponding excitation field to a substance under test in an NMR system is presented. The excitation signal is generated, according to a broadband transmitter, to a coil in the NMR system. A corresponding broadband receiver is also presented that acquires a response signal resulting from a response field emanating from the substance under test. Neither the transmitter nor the receiver require that the frequency of operation be determined according to a particular configuration of electrical devices to determine a resonance characteristic that tunes to a particular operational frequency. Rather, the operational frequency is determined according to control and driver devices triggered according to command and control signals in the case of the transmitter, and according to reactive elements, that are not configured as a tuned circuit, in the case of the receiver.
