- Abstract:
- In this paper a Nuclear Magnetic Resonance magnetometer (NMR) in a form of a LabVIEW Virtual instrument (VI) is proposed. The heart of the magnetometer remains the marginal oscillator with a proton sample. The magnetic resonance signal and all other auxiliary signals are generated and controlled by a set-up composed of a digital counter (for resonance frequency measuring), a VXI system (for the modulation signal generation and for the sampling of the oscillator output), a programmable DC voltage source (for oscillator frequency control) and a personal computer controlling the measurement. The virtual magnetometer was built and preliminary test measurements were done. The measuring results of the determination of a field-coil coilconstant showed that the virtual NMR magnetometer’s readings were comparable to the classic NMR magnetometer’s within 5·10-4.
