Abstract：The voltage standing wave ratio (VSWR) is a traditional parameter that characterizes the reflection characteristics in the radio field. There are still application scenarios. However, the reports on the measurement uncertainty of VSWR in some laboratories are not perfect. The evaluation results of VSWRs measurement uncertainty by GUM method of linear and nonlinear measurement model are compared with the results of Monte Carlo method (MCM).A quick GUM method is introduced which can replace MCM and be extended to any one variable measurement model under the common conditions.
