The paper is devoted to the investigation of mutual influence of low-frequency and microwave resonances in 87Rb vapor cell magnetome-ters system with laser pumping. One of the magnetometers was based on a low-frequency spin generator principle, while the second one was built as passive microwave spectrometer with a resonance frequency lock loop. The paper analyzes the frequency shifts in the low-frequency and microwave channels of the tandem of magnetometers associated with the simultaneous action of the resonant radio fields on the alkali atoms. Such effect is manifested in the frequency shifts of the spin generator for fixed changes in the amplitude of the microwave field.
