【摘要】：數(shù)字調(diào)制質(zhì)量參數(shù)目前還缺乏完善的量值溯源體系,開展全國性量值比對是推進該量值測量結(jié)果統(tǒng)一性的有效途徑。首先對自主提出的矢量信號源傳遞標準研制方法進行簡要的闡述,其次,在對目前市場主流的矢量信號分析儀進行大量比對測量的基礎(chǔ)上,發(fā)現(xiàn)了2處由于算法定義的區(qū)別導致測量結(jié)果的差異,進行了理論分析和公式推導,并通過測量實驗驗證了理論分析的正確性,從而為推進該參量的量值統(tǒng)一奠定基礎(chǔ),有利于提高該量值測量結(jié)果的準確性和一致性。
[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.
