The Rohde & Schwarz CMD60 is a compact digital radiocommunication tester engineered for production, service, and development testing of wireless devices across DECT and GSM standards. It consolidates RF measurements, audio testing, and signal generation into a single instrument, eliminating the need for multiple conventional test systems and reducing overall capital investment.
