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 IEEE802.11ac/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 baseband and four fading simulator modules – without compromising 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 multistandard 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.

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 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.

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.

GROWS WITH YOUR NEEDS

Advanced technology and a modular, upgradeable hardware concept make the R&S SMW200A a future-ready investment.

R&S SMW200A hardware options can be retrofitted with minimum effort. The baseband modules come as plugins and can easily be inserted into the rear panel without opening or recalibrating the instrument.

Software functions (e.g. digital standards) are simply activated via key codes. The R&S SMW200A firmware can be updated from a USB flash drive or via LAN. Free updates can be downloaded from the R&S website.

In this way, the R&S SMW200A can be precisely customized to suit the applications at hand and can be enhanced whenever new requirements arise. Users only have to purchase what they currently need and are free to decide on upgrades according to future requirements.

The Rohde & Schwarz SMCV100B vector signal generator features a new direct RF DAC concept for RF signal generation. This concept enables I/Q modulation and upconversion in the digital domain, which eliminates the I and Q imbalance errors and LO leakage associated with traditional analog I/Q modulators.

The R&S SMCV100B options concept is fully software defined. No hardware options are required to obtain full  nstrument functionality. This software concept applies to upgrading the RF frequency, memory, I/Q modulation  bandwidth and all other R&S SMCV100B options for other applications.

Powerful Internal Baseband Generator

The R&S SMCV100B provides powerful hardware for internal baseband signal generation. The R&S SMCV100B either generates signals in real time in FPGAs or it uses the ARB generator to directly generate I/Q signals for digital communications standards. The R&S WinIQSIM2™ signal simulation software can also be used to generate I/Q signals.

Real-time signal generation in FPGAs is especially used for broadcast standards. This technological approach enables continuous and very long uninterrupted signal generation with different data content (audio, video, data, PRBS) for decoding. Such long sequences are required for testing the performance or EMC of tuners.

5″ Touch Display in a 2 HU Instrument

The high-resolution 5″ touch display and clearly structured block diagram user interface enable simple and intuitive operation at all times. The user instantly sees the signal flow in the R&S SMCV100B as well as the states of the instrument inputs and outputs. An integrated graphic function displays the generated signal in real time.
