【摘要】 在核磁共振谱仪中 ,射频发射通道、接收机以及数据采集等的实时控制是由“脉冲序列器”来完成的 .本文提出了一套可设计任意脉冲序列、由全软件构成的“脉冲序列程序器” ,该软件用Delphi 5实现 ,用户界面简洁直观 .由其产生的脉冲的最小脉宽为 1 .3μs,分辨率为 1 2ns(CPU工作在 3 3 3MHz)更多还原

【Abstract】 Pulse programmer is an essential component in nuclear magnetic resonance spectrometer. In this paper, a pulse programmer, developed using Delphi 5, implemented totally by software will be discussed in detail. It can generate pulses with 12 ns resolution and 1.3 μs minimal width when the CPU clock is 333 MHz. Some experiments will be shown to demonstrate the features of this software pulse programmer.更多还原
