R&S SMW200A 20 GHz vector signal generator

Rohde & Schwarz has expanded the frequency range of its R&S SMW200A high-end vector signal generator to 20 GHz. The instrument combines a baseband generator, RF generator and fading simulator in a single box. In addition, it can be equipped with a second 20 GHz path, making it possible to simultaneously generate up to two wideband microwave signals with any type of modulation.

The instrument’s ability to combine a 6 GHz and a 20 GHz path in a single box enables users to quickly and easily perform the receiver and performance tests required by many telecommunications standards - no matter whether they need only the wanted signal or, in addition, interferers and perhaps even fading or additive white Gaussian noise (AWGN). The device accommodates all of these requirements and can generate signals in an application-compliant way. Using informative block diagrams on a touch screen, users can quickly configure the relevant signal parameters.

The R&S SMW-B120 microwave option up to 20 GHz supports numerous A&D applications in the X and Ku bands. The vector signal generator also delivers phase-coherent signals for testing phased array antennas.

With the integrated test case wizard, users can configure even complex WCDMA or LTE test scenarios with the required wanted signal along with an interfering signal and fading or AWGN with the press of a button.

The internal baseband generator already supports a large signal bandwidth up to 160 MHz. Using external I/Q signals, the signal bandwidth can even extend up to 2 GHz. Using the optional fading simulator, MIMO scenarios can be simulated in a reproducible way, making it possible to quickly configure even higher MIMO modes such as 2x2, 4x4 or 8x2. All functions of the R&S SMW200A can be easily remotely controlled via GPIB, LAN or USB.
