Master oscillator-METER FOR relaxometer nuclear magnetic resonance

摘要

The invention relates to devices for radio frequency spectroscopy and can be used in the composition relaxometer nuclear magnetic resonance (NMR). The technical result - expanding the scope of a digital computing device so that it can be used as a master oscillator and RF pulse sequences measuring the spin echo signal in the composition of nuclear magnetic resonance relaxometer. Technical result is achieved by the digital computing device is connected to relaxometer, and programmable logic array computing device incorporated control unit, coupled to the adder control unit of a direct digital frequency synthesis, phase shift adder, a digital integrator, the phase shift of the adder output is connected to the address input of the ROM memory device for the direct digital synthesis sine wave whose output is connected to the input of the multiplexer, the multiplexer output via relaxometer and analog-to-digital converter coupled to the input of the digital integrator whose output is connected to the input of RAM programmable logic array, which is output from the control unit and an interface connected to a personal computer.
