摘要

When design RF architecture of base station or repeater, EVM is a key parameter to measure the system's quality. The traditional EVM test bench is composed of signal generator and analysis instrument such as spectrum analyzer, oscilloscope or vector signal analyzer. The whole system is complex and expensive. Using Electronic System-Level (ESL) software SystemVue and filter's S parameter measured by VNA, filters' EVM could be simulated for different communication standards. The Pearson produce-moment correlation coefficient between the simulation and measurement results is used to validate the correctness and applicability of the methodology.
