Abstract: The new scheme of a combined quantum magnetometric device is proposed that represents a fast $M_X$ magnetometer, in which the phase of $M_X$ signal detection is corrected with respect to the maximum of the variable component of the atomic magnetic moment. The device combines a high response speed ($\tau\le$ 0.1 s) with high precision, which is determined by the resolving power of the quantum $M_X$ magnetometer for a time of an order of 100 s. The reproducibility of field measurements is on a level of 2–3 pT.
