基于81150A的晶体振荡器振动测试平台设计

摘要

本文根据实验室已有的设备搭建了晶体振荡器振动测试平台，采用了安捷伦81150A函数发生器，并利用MATLAB产生特定频谱的数据，然后通过波形编辑器把信号数据输入到81150A中，从而产生所需的驱动信号。驱动信号可通过功率放大器驱动振动电机。该振动平台体积小，使用方便且价格较低，振动模式可以自行设定，完全能够满足晶体振荡器振动测试的要求，具有一定的应用价值。%T he volume of professional vibration test platform is large ,it needs special places ,and it is very expensive .So it is not suitable for vibration test of crystal oscillator .Crystal oscillator vibration test platform is built according to the existing laboratory equipment .An agilent 81150A function generator is applied .T he special spectrum signal is generated by MATLAB .MATLAB signal is transformed to 81150A function gener-ator by the waveform editor .81150A generates analog signal which is amplified to drive the motor .The vi-bration platform has the advantages of small volume ,convenient to use and low price ,so it’s fully able to meet the requirements of the quartz crystal oscillator vibration test .
