Rohde & Schwarz has upgraded its SMW200A high-end vector signal generator, so that it can generate two wideband signals with any type of modulation up to 20 GHz using a single device, and also fading and MIMO scenarios can be configured over the entire frequency range. The designers in the domain of wireless communications and aerospace & defense industries are expected to benefit from this product.
SMW200A packs baseband generator, RF generator and fading simulator in single unit. By ability to have a second 20 GHz path SMW200A can be used to generate up to two wideband microwave signals with any type of modulation.
R&S says 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 ‒ no matter whether they need only the wanted signal or, in addition, interferers and perhaps even fading or additive white Gaussian noise (AWGN).
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.
By having integrated test case wizard, users can configure complex WCDMA or LTE test scenarios with the required wanted signal along with an interfering signal and fading or AWGN ‒ by simple 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 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.
