代码说明：

1．采用Labview设计一虚拟函数信号发生器，通过数据采集卡输出波形信号，调节信号的相关参数，可观察示波器上波形的变化情况。 ⑴ 以NI MyDAQ数据采集卡作为输出接口； ⑵ 数据采集卡输出多种信号，至少完成三种波形：正弦波、三角波、方波(可调占空比)的输出，同时前面板上显示各输出波形； ⑶ 频率、幅值、初相位、直流偏移量和方波的占空比（0～100 ）等参数可以通过前面板控件调节。 ⑷ 前面板可显示输出波形。(1. Labview design using a virtual function signal generator, data acquisition card output waveform signal, adjust the relevant parameters of the signal can be observed on an oscilloscope waveform changes. ⑴ with NI MyDAQ data acquisition card as output interface ⑵ data acquisition card output a variety of signals, to complete at least three waveforms: sine wave output, triangle wave, square wave (adjustable duty cycle), while each of the output waveform is displayed on the front panel ⑶ frequency, amplitude, initial phase, the DC offset and duty cycle square wave (0 to 100 ) and other parameters via the front panel controls to adjust. ⑷ output waveform can be displayed on the front panel.)

利用Labview平台，实现了指定格式的xml与xls文件的互转功能，其中xml端利用Labview内部函数，xls端利用下载的dll函数。虽然不是通用互转系统，但仍然对labvie环境下xml编程和excel编程很有帮助。(The the Labview platform to achieve a specified format xml with the xls file Huzhuan function, in which the xml end to using Labview internal function, xls to end the use of the downloaded dll function. Although not the Universal Huzhuan system, but still helpful the xml programming labvie environment and excel programming.)

3-1正余弦波形
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.)
