The Rigol VB1080 is a VSWR bridge accessory that enables S11-parameter measurement on compatible Rigol spectrum analyzers equipped with tracking generator functionality. It measures return loss, reflection coefficient, and VSWR to characterize impedance matching and signal transmission efficiency in RF systems. The bridge also supports S22 measurements for output-port analysis. Direct front-panel connection to the host analyzer eliminates external cabling, improving measurement accuracy and simplifying test setup.
