Communication Analyzer : Rohde & Schwarz CMS54

The family of Radiocommunication Service Monitors CMS comprises two models. These radio testers allow transmitter, receiver and duplex measurements to be performed on mobile radios, base stations or RF modules. The CMS family monitors are ideal radio testers for service, maintenance and test departments.
CMS – a test set replacing many individual measuring instruments

Due to the comprehensive standard configuration of the individual models and the optional extensions tailored to specific applications, external measuring instruments in addition to the CMS are not required.
