摘　　要：针对虚拟数字示波器(VDOS)实现的问题,提出实现物理仪器驱动库、虚拟仪器驱动库和仪器软面板软件的原理及方法,给出常用波形运算公式,并编制物理仪器驱动库、虚拟仪器驱动库及仪器软面板实现软件。最后选取一组实例对使用上述原理的VDOS进行综合评价,评价结果表明,VDOS能程控物理仪器的各种操作,能用于波形参数测试,能用于虚拟仪器仿真。上述VDOS用于程控物理仪器及仿真是有效的。For the problem that exists in the realization of virtual digital oscilloscope （VDOS）,the principles and methods were proposed to realize the physical instrument driver libraries,virtual instrument driver libraries and in- strument panel software at the first step. Then,the common waveform calculation formulas were given,and the physi- cal instrument driver libraries ,virtual instrument driver libraries and instrument panel software were prepared accord- ingly. Finally,a set of instances were selected to comprehensively evaluate the VDOS which were realized according to the above principles. The results show that the VDOS can be programmed physical instruments＇ various operations,test waveform parameters and simulate virtual instrument. In a word,the VDOS mentioned above was valid for programming and simulating physical instrument.
