R&S®SMW200A Vector Signal Generator adds wideband signal generation for 5G, 802.11ad, radar, and more


The R&S®SMW200A is the vector signal generator for the most demanding applications. As a result of its flexibility, performance and intuitive operation, it is a perfect tool for generating complex, digitally modulated signals of high quality.

The R&S®SMW200A is the ideal generator for digitally modulated signals required for the development of new wideband communications systems, the verification of 3G and 4G base stations or in the aerospace and defense sector.

The I/Q modulation bandwidth of up to 2 GHz with internal baseband satisfies fourth- and fifth-generation standards (e.g. 5G, LTE-Advanced and IEEE 802.11ac/ad), and the R&S®SMW200A is designed to meet future requirements. Its modular scalable architecture allows users to optimize the generator to their applications and to upgrade it as required.

A second RF path can be added, as well as a maximum of two base-band and four fading simulator modules – without compromising on signal quality. As a result, the R&S®SMW200A can create signal scenarios that previously required multiple instruments or could not be implemented at all. From MIMO up to 8×2 and LTE-Advanced carrier aggregation including fading to multi-standard radio – never before has an instrument offered such high-class signal generation capability.

If more than two RF paths are required, additional R&S®SGMA signal generator modules can be connected. The intuitive, touchscreen-based operating concept provides the user with an overview of measurements, no matter how complex, and quickly delivers the desired results.

Key Facts

  • Options for all important digital communications standards
  • Optional integrated fading simulator with up to 160 MHz bandwidth
  • Support of all key MIMO modes including 3×3, 4×4, 8×4, 4×8 and 4x2x2

Versatile Configuration

Thanks to its modular design, the R&S®SMW200A can be equipped with the exact options required for a specific application. Any configuration is possible, from a classic single-path vector signal generator to a multichannel MIMO receiver tester. The generator can be equipped with a maximum of two internal baseband modules and four fading simulator modules. It is also possible to install a second 3 GHz or 6 GHz RF path. This concept yields two full-featured vector signal generators in a single unit so that even complex signal scenarios (e.g. wanted signal + interferer, dual cell, TX/RX diversity) can be created easily.

Ideal for MIMO, MSR or LTE-Advanced applications

And that is by far not all. The capabilities of the R&S®SMW200A surpass those of two conventional generators combined. When the instrument is fully equipped, the baseband section provides up to eight independent signal sources and up to 16 logical faders. This makes the R&S®SMW200A ideal for MIMO and other complex applications encountered in LTE‑Advanced (carrier aggregation), HSPA (dual carrier) and multistandard radio, etc.

Modular architecture for optimal adaptation to the application at hand

Almost all options of the R&S®SMW200A can be retrofitted, most of them simply via key code. Starting from the basic configuration as a classic single-path vector signal generator, the R&S®SMW200A can be customized as required for any application. Users only have to purchase what they currently need and are free to decide on upgrades according to their future requirements.
