Generator for scanning the magnetic field in a MNR wide line spectrometer

A circuit of a generator for fast scanning (0.01-250 s) of a magnetic field is described. The generator is characterized by an increased output power and is intended for use in broad-line spectrometers. The high linearity and stability of output voltage amplitude permit the employment of the generator for operation with a digital storage without using complicated synchronizing circuits. Records of NMR lines of the 297Pb isotope in p-PbTe obtained by a fast scanning method with data storage and a method of differential transmission are presented. They witness to the advantage of the first one (a considerable reduction of the signal recording time)
