R&S SMW200A vector signal generator supports 20 GHz

June 4, 2014. Rohde & Schwarz has expanded the frequency range of its R&S SMW200A high-end vector signal generator to 20 GHz. The R&S SMW200A combines a baseband generator, RF generator, and fading simulator in a single box. In addition, the R&S SMW200A 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.

Users in the wireless communications and aerospace and defense industries in particular will benefit from the new options. The instrument's capability of combining a 6-GHz and a 20-GHz path in a single box allows users to quickly and easily perform the receiver and performance tests required by many telecommunications standards. The R&S SMW200A 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, for example. If more than two phase-coherent signals are needed, extra R&S SMW200A generators can be added.

Thanks to 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 (additive white Gaussian noise).

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 2×2, 4×4, or 8×2. All functions of the R&S SMW200A can be easily remotely controlled via GPIB, LAN or USB.
