说明：  采用cvi语言编写 对agilent 34970a万用表进行初始化设置，可作为在 labwindows/cvi使用agilent 34970a万用表进行数据采集的参考代码(Cvi language used to initialize agilent 34970a multimeter settings, can be used as in labwindows/cvi using agilent 34970a multimeter for data collection reference code)

说明：  用LabVIEW读取Excel数据，已使用，效果不错，教程不错。(Read the excel data with LabVIEW!)

在波形Graph显件上用两种不同颜色显示一条正弦曲线和一条余弦曲线，每 条曲线长度为128个点，其中正弦曲线的x0 =0，△x=1；余弦曲线的x0 =2， △x=5。并利用属性节点通过前面板控件改变每条曲线的颜色。 ①一个周期128点。 ②改变颜色一定要先选择曲线，然后再改变颜色。(A sine curve and a cosine curve are displayed in two different colors on the waveform Graph display. The length of the bar curve is 128 points, where the sine curve x0 =0, Delta x=1, the cosine curve x0 =2, Delta x=5. And use the attribute node to change the color of each curve through the front panel control. One cycle is 128 points. Change the color must first choose the curve, then change the color.)

倍频程带通滤波器,实现倍频程分析和计算信号的有效值(Octave bandpass filter to achieve octave analysis and calculate the effective value of the signal)

实时求解振动信号的频率响应，可以用在数据采集过程中实时观察振动信号的频率响应(Frequency response in real time to solve the vibration signal can be used in the data collection process in real-time observation of the frequency response of the vibration signal)
