通过labview控制信号发生器和锁相放大器进行共振频率检测的程序。freq test.vi实现信号发生器的频率扫描，lockin test.vi 实现锁相放大器的参数设定，数据采集.vi实现锁相数据的采集，waveform arrays to file实现波形数据到文件数据的转换。共振频率测试.vi实现晶振等共振频率的测试(Resonance frequency detection procedures performed by labview control signal generator and lock-in amplifier. freq test.vi achieve frequency sweep signal generator, lockin test.vi setting parameters to achieve lock-in amplifier, a data acquisition. vi achieve phase lock data acquisition, waveform arrays to file converted waveform data to achieve document data. The resonance frequency of the test. Vi achieve crystal and other resonant frequency test)

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.)
