Due to its outstanding performance the R&S SMW200A vector signal generator is ideal for testing MIMO receivers in a vast variety of applications offering maximum usability at minimum form factor. It can generate up to eight antenna signals simultaneously in its digital baseband—all standard-compliant and with antenna-specific coding. In addition, it can simulate the complete MIMO transmission channel with up to 16 fading channels, sufficient to emulate higher-order MIMO configurations such as 3×3, 4×4, and 8×2. This application note explains how to use the SMW for testing higher order MIMO systems by presenting different key applications.
