The new 3G mobile radio standard UMTS is on its marks and Rohde & Schwarz supports the industry in this particular technical challenge with high-grade test equipment. The new 3G Virtual Protocol Test System R&S CRTU-VT combines a complete TTCN software development environment, verified 3G signalling test cases and powerful analysis tools for the simulation and testing of 3G UE protocol stacks. The virtual tester is based on modified software installed on the Protocol Tester R&S CRTU-W and is an excellent comple-mentary tool to this tester, the R&S CRTU-VT being able to carry out the early-stage comprehensive test of signalling sequences in 3G networks.
