Measurement Uncertainty Evaluation of Digital Modulation Quality Parameters: Magnitude Error and Phase Error
Zhiqiang Zhan, Junwen Xia, Yunling Wang, Lei Yu · MATEC Web of Conferences · 2016
In digital modulation quality parameters traceability, the Error Vector Magnitude, Magnitude Error and Phase Error must be traced, and the measurement uncertainty of the above parameters needs to be assessed. Although the calibration specification JJF1128-2004 Calibration Specification for Vector Signal Analyzers is published domestically, the measurement uncertainty evaluation is unreasonable, the parameters selected is incorrect, and not all error terms are selected in measurement uncertainty evaluation. This article lists formula about magnitude error and phase error, than presents the measurement uncertainty evaluation processes for magnitude error and phase errors.
