In addition, the 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. For these types of complex setups, other setups require at least three devices and considerably more effort for settings, synchronization and cabling.

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 SMW200A accommodates all of these requirements and can generate signals in an application-compliant way. Using informative block diagrams on a touchscreen, users can quickly configure the relevant signal parameters.

The 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 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 — all at the press of a button. Time-consuming, error-prone manual parameter entries are a thing of the past.

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 SMW200A can be easily remotely controlled via GPIB, LAN or USB.
