| Abstract: | To meet the functionality requirements and the trend of instrument miniaturization, a miniaturized NMR spectrometer console system based on field programmable gate array (FPGA) and advanced RISC machines (ARM) is proposed. This digital console has the advantages of extremely high processing speed, accurate control, short development cycle and low costs. In this paper, we introduce the functions of FPGA in the system, including data receiving, parameter configuration, pulse emission and data sampling modules. The ARM embedded module achieves the function of Ethernet communication between the console and host computer, such that the internal operation of the console will not be disturbed by the network status. |
