摘　　要：为了实现阿伦方差的灵活测试,摆脱专用测试仪器的限制,避免因短稳测试仪故障导致测试中断的问题,设计了一种由相位噪声计算阿伦方差的测试软件。首先通过理论推导得到相位噪声转换阿伦方差的关系表达式,其次利用MATLAB对相位噪声数据进行采集和处理,通过转换公式间接计算出阿伦方差,结果显示测试精度可达到10^(-11)量级。与短稳测试仪(PN9000)相比,测试结果可达到同一数量级,能够满足测试要求。利用MATLAB提供的GUI模块开发设计,为测试工程师提供了友好又简洁的操作界面,提高了测试效率。In order to achieve the test of Allan variance,the paper designs a test software which can converts Allan variance from phase noise.Firstly,the relational expression of Allen variance in phase noise conversion is obtained by theoretical deduction.It transforms phase noise to Allan variance by using MATLAB to collect and process the data of phase noise.Compared with the PN900,the comparison shows that the result almost meets the test level of PN9000.It shows a friendly interfaces and convenient operation by using the GUI module provided by MATLAB.The software provides anew test method for Allan variance,which effectively avoids the problem of test interruption caused the failure,and greatly improves the test efficiency.
