AMU200A - Rohde & Schwarz Signal Generators

The R&S®AMU200A baseband signal generator and fading simulator has been designed to meet all requirements encountered in the research and development of modern communications systems as well as in their production. The R&S®AMU200A not only combines up to two independent baseband signal generators in one cabinet of only four height units, but also offers unrivaled channel simulation capabilities.

Due to its modular design, the R&S®AMU200A can be optimally adapted to the requirements of different applications. Up to two generators can be installed. They generate complex signals in realtime and are equipped with an arbitrary waveform generator with 16 Msample, 64 Msample, or 128 Msample memory for I and Q and four marker bits per sample. The signals generated in the different basebands can be added, even with frequency, phase, and level offset. The modern, intuitive concept of the R&S®AMU200A ensures fast and easy operation.
