基于LABVIEW的数据采集的框图程序，用于采集信号数据并保存(Of the block diagram of data acquisition based on LABVIEW program, used to collect signal and save the data )

航空航天通信技术一般采用模拟通信的频率调制和数字通信的移相键控调制方法。这有利于充分应用信道带宽和能源。频率调制是在一定程度上改变载波或副载波的频率来传输信息的调制方法。移相键控调制是利用载波或副载波的相位跳变来传输信息的调制方法。移相键控又分二相移相键控、四相移相键控和多相移相键控，其中以四相移相键控和八相移相键控调制方法的效率较高(Aerospace communications technology commonly used analog communication of frequency modulation and the digital communication phase shift keying modulation method. This is helpful for making full use of channel bandwidth and energy. Frequency modulation is changed to some extent carrier or subcarrier frequency to transmit information modulation method. Phase shift keying modulation is the use of carrier or subcarrier phase jump to transmit information modulation method. Phase shift keying and binary phase shift keying, four phase shift keying and multiple phase shift keying, of which four phase shift keying and eight phase shift keying modulation method of high efficiency )

说明：  控制转台旋转角度情况下，7路光功率计同时探测光强变化，联谊和thorlabs设备，需导入子vi。(Under the condition of controlling the rotation Angle of the turntable, the 7-channel optical power meter can simultaneously detect the change of light intensity.)

新建子VI（test2 oise_testing.vi），运用Express VI，实现噪声信号的采集、处理、显示和存储(The new sub VI (test2 oise_testing.vi) uses Express VI to realize the acquisition, processing, display and storage of noise signals)

基于LabvIEw的通用自动测试系统(ATs)舍计算机，可鳊程激励、响应数据采集及uuT模块，采用MxI总线控制方式。专用信号发生器为uuT提供模拟激励信号，矩阵开关和适配器完成不同信号间切换。主控计算机执行测试程序，信号发生器发送激励信号，数据采集卡采集数据，采集数据经调理后，并与标准数据|匕较是否满足相应测试结果。(The general automatic test system (ATs) based on LabvIEw can be used as a computer to excite, respond to data acquisition and uuT module. The control mode of MxI bus is adopted. Special signal generator provides analog excitation signal for uuT, matrix switch and adapter complete switching between different signals. The main control computer executes the test program, the signal generator sends the excitation signal, the data acquisition card collects the data, after the data acquisition is adjusted, and compares with the standard data | dagger whether it meets the corresponding test results.)
