CDMA2000 1xEV-DO Tester Upgraded To Rev A Standard

The Rohde & Schwarz CMU200 universal communications tester now supports CDMA2000 1xEV-DO Revision A. The new capabilities are provided as a firmware upgrade for instruments with 1xEV-DO Revision 0 functionality. The new firmware allows manufacturers, service centers, and service providers to perform end-to-end testing of both RF and data parameters to ensure proper functioning of a product under the wide range of operating conditions it will experience. The measurements performed by the CMU200 comply with the full range of minimum performance tests identified in IS-866-A, Minimum Performance Specification. Additionally, the CMU200 now supports hybrid mode in which two synchronized instruments can perform voice and data testing together.

CDMA2000 1xEV-DO Revision A brings significant enhancements to the initial standard (Revision 0), including an increase in maximum data rates from 2.4 Mbits/s to 3.1 Mbits/s in the forward link and from 153.6 kbits/s to 1.8 Mbits/s in the reverse link. In addition, Revision A introduces enhancements for latency-sensitive and/or delay-sensitive applications such as enhanced push-to-talk, multi-player gaming, laptop-based video conferencing, Voice over Internet protocol (VoIP), and Instant Multimedia Messaging (IMM).

AVAILABILITY

The firmware, Version 4.30, is available now.

PRICING

The firmware is a free upgrade for owners of CMU200s with CDMA2000 1xEV-DO Rev 0 capability.
