The voltage standing wave ratio (VSWR) is one of the parameters in RF systems that measures the impedance mismatch. Under ideal conditions, when the load is perfectly matched to the source, the VSWR will be 1. A mismatch in the system causes reflections that will increase the VSWR and lead to losses in transmission. Although most RF components are typically designed and specified with a characteristic impedance of 50 Ω , applications and system components for cable television are designed and specified with a characteristic impedance of 75 Ω . This application note describes the measurement procedure for VSWR measurements in 75 Ω systems using the R&S®FSH3-TV handheld TV analyzer.
