虚拟一个PXI-4472，编制一个完整的LabVIEW软件，完成功能如下：



1、8个通道模拟信号连续采集、显示和记录（存盘）；



2、采样率、耦合方式、记录时间（最长60min）、记录文件名和路径等可以在面板设置；



3、记录文件可以读取显示，可选择显示的通道，每屏显示1000个数据，利用滚动条可以定位文件读取起始位置，并自动向后滚动，通过暂停键可以暂停；



4、对显示窗口的波形数据，可以显示波形的有效值、峰峰值、频率等参数；



5、具有光标功能，可以读取光标处的幅值、时间；



6、可以最大化界面，界面不应有明显变形，点击退出按钮可以正常退出。-A virtual PXI-4472, the preparation of a complete LabVIEW software, complete the following functions:

1, 8 channel analog signal acquisition, display and record the continuous (Cun Pan)

2, sampling rate, coupled mode, recording time (maximum 60min), recording the path and file name can be arranged on the panel

3, record file you can read the display, can display the channel, each screen shows 1000 data, use the scroll bar to locate the file read starting position, and automatically roll back, through the pause button to pause

4, to display the waveform data window, can show the effective value, peak value, frequency and waveform parameters

5, with cursor function, can be amplitude, time to read the cursor

6, you can maximize the interface, there should be no obvious deformation interface, click the exit button can be normal exit.
