2 Broadcast Test System R&S SFU Version 03.00, March 2005
Introduction
The Broadcast Test System R&S SFU has been designed as a platform for different applications and for future options. It combines
several instruments in one cabinet of only four height units to offer unrivaled RF and baseband characteristics.
Due to its modular design, the R&S SFU can be optimally adapted to the requirements of different applications. It is an ideal research
and development tool for making improvements to introduced standards and for generating new standard signals. Applications that
previously required many different instruments are now fully covered by the R&S SFU. The modern, intuitive concept of the R&S SFU
ensures fast and easy operation.
Application overview
