【摘要】：数字调制质量参数目前还缺乏完善的量值溯源体系,开展全国性量值比对是推进该量值测量结果统一性的有效途径。首先对自主提出的矢量信号源传递标准研制方法进行简要的阐述,其次,在对目前市场主流的矢量信号分析仪进行大量比对测量的基础上,发现了2处由于算法定义的区别导致测量结果的差异,进行了理论分析和公式推导,并通过测量实验验证了理论分析的正确性,从而为推进该参量的量值统一奠定基础,有利于提高该量值测量结果的准确性和一致性。
[Abstract]:There is no perfect traceability system for digital modulation quality parameters at present. It is an effective way to promote the uniformity of the measurement results to carry out nationwide quantitative comparison. First of all, the development method of vector signal source transmission standard proposed by ourselves is briefly described. Secondly, on the basis of a large number of comparative measurements of vector signal analyzer which is the mainstream of the market at present, It is found that the difference of measurement results is caused by the difference of the definition of the two algorithms. The theoretical analysis and formula derivation are carried out, and the correctness of the theoretical analysis is verified by the measurement experiment, which lays a foundation for promoting the unification of the values of this parameter. It is helpful to improve the accuracy and consistency of the measurement results.
