The theory of an autodyne spin generator (ASG), which is a spin generator on the side. band with modulation of the HF field, is given. In its construction, the ASG consists of a nonisochronous audyne sensor of NMR signals with a working sample in the coil of an oscillatory loop. It is shown that excitation of spin generation becomes possible as a result of mixed amplitude-frequency modulation of the autodyne oscillations, ensuring satisfaction of the condition of phase balance at near-Larmor frequencies.
