Title:
MAGNETIC RESONANCE SPECTROMETER AND CONTROL APPARATUS FOR MAGNETIC RESONANCE SPECTROMETER BASED ON FPGA
Document Type and Number:
WIPO Patent Application WO/2017/190307
Kind Code:
A1
Abstract:
A magnetic resonance spectrometer and a control apparatus for the magnetic resonance spectrometer based on an FPGA. The control apparatus comprises a control unit (200) and a conversion receiving unit (300). The control unit (200) comprises a clock source (100). A waveform generation unit and a signal receiving unit (320) inside the control apparatus are synchronized by means of the same clock source. The control apparatus comprises two working modes: a continuous wave mode and an impulse wave mode. The control apparatus can output a microwave signal which is modulated by any wave and has higher synchronism and time resolution compared with a control apparatus for an electron paramagnetic resonance spectrometer using a plurality of separate clock sources in the prior art, this enables a second microwave signal in a pulse form generated by the electron paramagnetic resonance spectrometer that is under the control of the apparatus to have a small minimum resolvable time of a pulse width and a pulse relative time delay, i.e. the time resolution of the second microwave signal being high. The control apparatus is designed based on an FPGA, and has a high integration level, a flexible design and low costs.
