标准简介

适用范围：

This standard provides recommended practices for the determination of uncertainty in the estimation of error vector magnitude (EVM) of a measured digitally modulated wireless communication signal. Such practices include several methods for validating a user's measurement of a specific reference waveform by comparison to a reference measurement. The methods differ based on the level of rigor desired by the user and the accessibility to timing and waveform recording capabilities of the available… read more hardware. Methods for evaluating measurement uncertainty in EVM are also presented. Some of the methods described here focus on measurements and uncertainties related to the use of laboratory-based measurement equipment such as vector receivers, real-time and equivalent-time sampling oscilloscopes and other types of waveform recorders that have access to the measured waveform. This allows time-alignment and gain normalization of measured waveforms prior to the calculation of EVM. Other methods focus on specialized receivers that report symbols directly. As part of the assessment of the measurement hardware and associated uncertainty analyses, this practice includes a mathematically rigorous method for the determination of EVM. read less
