For more than 10 years Rohde & Schwarz has been successful in the market with the reference systems CRTP02 and CRTC02 for development and conformance testing of GSM mobile phones. Higher standards for applications and frequent changes of the GSM specification made it necessary to continually adapt the testers to the new requirements. A point has been reached now where a
new platform has to be introduced to cope with the versatile requirements: the Universal Protocol Tester CRTU-G. It is based on a future-proof RF unit that can be upgraded to meet future
standards.
