Racal Instruments develop first transmitter measurement test system for Chinese 3G standard ahead of time

date: June 14, 2002

The Wireless Solutions Group of Racal Instruments, working under its cooperation agreement with the Chinese Academy of Telecommunications Technology (CATT), has developed the first software system T-AIR, for measuring transmitter performance of 3G mobiles designed to meet the Chinese standard, TD-SCDMA. Ahead of schedule, this is the first in a series of planned products from Racal delivering previously unattainable measurement capabilities and giving manufacturers confidence in mobile performance. In allowing designs to be evaluated at a very early stage T-AIR has the potential to shorten the development cycle and help manufacturers produce more robust designs.

Stephen Hire of Racal Instruments commented, "It is important that Racal is a key player in the Chinese market which by 2004 will be the world's largest with potentially 250 million subscribers. The Chinese market currently has 40 licensed mobile manufacturers."

Zhang Dai-Jun, General manager of UE R&D Dept. of 3G standard development for CATT said, "Racal's test solution has been of great value to us in evaluating the performance of our TD-SCDMA UE transmitters. Using this solution we are able to perform measurements we had previously been unable to. This has been a great assistance in the development and proving of our 3G user equipment against the standards."

Until now engineers have been limited by digital spectrum analyser capabilities, which only provided raw I and Q data measurements. This made the analysis of a transmitter's performance exceptionally difficult, if not impossible. Recognising the need for better performance measurements Racal Instruments developed the T-AIR test solution.
