Abstract :
Presented absorption type proton magnetometer uses direct digital synthesizer and DSP instead of marginal oscillator, therefore frequency measurement uncertainty is negligible. Frequency modulation of high frequency signal is used instead of magnetic field modulation. With the magnetometer described and the existent permanent magnet the accreditation range of the LMM could be extended
