Abstract :
In this system, a Pulse Sequence Generator in P-NMR has been designed by an AT89S52 single chip computer control CPLD chip, EPM7128SLC84-15, which combined the high divisibility advantage of Single-chip Microcomputer and the high-speed character of CPLD. This system can generate the sequence such as CPMG, which can be applied to P-NMR. Experimental proof of the system´s a high precise pulse, a good flexibility of control, high cost performance.
