Brief Description

The R&S®SMU200A Vector Signal Generator not only combines up to two independent signal generators in one cabinet of only four height units, it also offers unrivalled RF and baseband characteristics. The generator has been designed to meet all requirements encountered in research and development of modern communication systems as well as in their production.

Due to its modular design, the R&S®SMU200A can be optimally adapted to the requirements of different applications. The first RF path can be equipped with one of the four available frequency options. The upper frequency limit of 2.2 GHz / 3 GHz / 4 GHz or 6 GHz is user-selectable. In addition, a second RF path can be installed with upper frequency limits of 2.2 GHz and 3 GHz. The lower frequency limit of all frequency options is 100 kHz.

Up to two generators can also be installed in the baseband section. They generate complex signals in realtime and are equipped with an arbitrary waveform generator with up to 128 Msample memory for I and Q (512 Mbyte). The signals generated in the different basebands can be added. Frequency offset of the individual signals is possible. The optional internal fading simulator provides up to 40 fading paths for simulating multipath propagation.

The R&S®SMU200A can be fitted with a wide range of options – for example, options for all of today's important digital standards as well as function and performance enhancements such as MIMO fading or phase coherence. For a list of all available options as well as links to detailed information about the individual options, see "ordering information".

The modern, intuitive concept of the R&S®SMU200A ensures fast and easy operation.
