矢量调制器测试数据的分析及提数方法设计

The Measure and the Application of the Vector Modulator

为了解决在从测试数据中提取模拟矢量调制器的数字控制数据时所产生的控制精度与测量时间之间的矛盾问题,本文通过对测试数据的分析,提出了通过对粗测数据进行插值后再提数的方法来解决该问题。实测数据表明,本文所设计的方法对模拟矢量调制器的幅相控制数据提取能达到较理想的结果,能有效的解决在工程应用中的问题。

In order to solve the conflicting between the massive data and the long time of measuring when getting the digital control data of the vector modulator, the paper introduces a systemic method which including of analyzing the measure data and the interpolation of the measure data. The experiment results show that the proposed method could get an satisfactory data of which controls the amplitude and phase of a vector modulator. Therefore, the method in the paper is a good guidance for using a vector modulator.
