【摘要】 虚拟信号测量仪的主要功能有两部分:测量电信号(如电压)和测量非电信号(如温度)。电信号部分显示器可以直观地显示采集的波形,并通过相应的函数模块处理,得到波形的直流分量、标准频率、峰值、平均值和有效值。非电信号部分的显示器按时间顺序以波形的形式显示所测得的值的历史变化趋势,并得出当前时间段信号的最大、最小和平均值。更多还原

【Abstract】 The main function of the virtual signal measurer has two parts,Surveying the electrical signal(for example voltage) and the non-electric signal(for example temperature).Not only the screen of the electrical signal partial can display the signal it gathered distinctly,but also the measurer can obtain the direct component,the standard frequency,the peak value,the mean value and the effective value of the signal by processing with the corresponding function modules.The screen of the non-electric signal part displays the historical tendency of the signal with a waveform according to the time order,and we can also obtain the maximal value,the minimal value and the mean value of the current time.更多还原
