USB-6008说明与使用注意事项lab运用与说明(6008 Description and Use Precautions)

说明：  使用全局变量 VI 实现动态数据从一个 VI 传送到别一个 VI 中。当两个 VI 同时运行时，观察对比两个 VI 的波形图，调节第一个 VI 的滑动 杆，再观察对比两边的波形，最后，按下第一个 VI 里的停止按钮时，第二个 VI 也能接收到停止信号，并停止第二个 VI 的运行。(Using global variable VI to transfer dynamic data from one VI to another Medium. When the two VI are running at the same time, observe and compare the waveform of the two VI, and adjust the sliding of the first VI Then observe and compare the waveforms on both sides. Finally, when pressing the stop button in the first VI, the second VI It can also receive the stop signal and stop the operation of the second VI.)

说明：  labview实现串口示波器的功能，读取示波器发送的浮点数数据，并绘制曲线(Serial port oscilloscope)

说明：  labview串口接收、发送（分开）程序以及总通信程序(LabVIEW serial port receive, send (separate) program and general communication program)

Labview的详细开发指南，包括：双精度数据不适于相等比较（内置函数）；顺序结构是“结构”吗？；到底什么是“节点”；XY GRAPH的输入参数形式 ；整型数据类型和内存映射；状态机的基本概念 ；状态机的基本类型顺序结构 ；状态机的基本类型之标准状态机 ；事件结构中的TIMEOUT进行数据采集合适吗 ；全局变量、移位寄存器和功能型全局变量的性能比较等。(Labview detailed development guidelines, including: double precision data is not suitable for equality comparison (built-in function) sequential structure is " structural" it? In the end what is " node" input parameters of the form XY GRAPH integer data types and memory mapping basic concept of the state machine basic types of sequential structure of the state machine basic types of state machine standard state machine event structure The TIMEOUT data collection suitable for you global variables, shift registers and functional performance comparison of global variables and so on.)

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.)
