Specifications apply under the following conditions: 30 minutes warm-up time at ambient temperature, specified environmental conditions met, calibration cycle adhered to, and all internal adjustments performed. Data designated “overrange” or “underrange” and data without tolerance limits is not binding.

EMC specifications are tested with sufficiently shielded cables and accessories (e.g. mouse and keypad). To prevent degradation of these specifications, it is the user's responsibility to use appropriate equipment.

In compliance with the 3GPP standard, chip rates are specified in Mcps (million chips per second), whereas bit rates and symbol rates are specified in kbps (thousand bits per second) or ksps (thousand symbols per second). Mcps, kbps and ksps are not SI units.

Device settings and GUI parameters are designated with the format "parameter: value".

SMU200A Vector Signal Generator 3

Version 08.00, January 2012

Introduction

The R&S®SMU200A vector signal generator has been designed to meet all requirements encountered in the research and development as well as production of modern communications systems. The R&S independent signal generators in one cabinet of only four height units, but also offers unrivaled RF and baseband characteristics.

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 an upper frequency limit of 2.2 GHz or 3 GHz. The lower frequency limit of all frequency options is 100 kHz.

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 16 Msample, 64 Msample or 128 Msample memory. The signals generated in the different basebands can be added, even with frequency offset.

Featuring a dual-path concept and an optional integrated multichannel fading simulator, the R&S receivers as 2x2 MIMO systems can be tested using a single instrument. For larger systems up to 2x4 or 4x2 MIMO, two instruments can be combined.

The modern, intuitive concept of the R&S

SMU200A ensures fast and easy operation.

SMU200A not only combines up to two

SMU200A is ideal for tests on MIMO
