| 摘 要： | 对周期性宽带码序列的频谱进行分析一般采用频谱仪。本文利用乘法器差频法对频谱进行简易测试的方案有设备价格低廉、避免滤波器动态特征引入的误差的优点。实验结果表明，用该方法的测试值与理论计算值相吻合，有实际应用价值。

| Abstract: | Spectrum analysis is very often using spectrum analyzer. The measuring method based on multiplier and beat frequency, it's device is cheep, provided against error from dynamic character of the filter. Experiment results show that the measuring data by the method is very close approach to calculating value. Thus, it is effetual. |
