Guidelines for MIMO Test Setups – Part 2

Multiple antenna systems, known as MIMO systems, form an essential part of today’s wireless communications standards. The multi-antenna technology efficiently boosts the data throughput without requiring additional bandwidth or transmit power and has thus become a key technology. Rohde & Schwarz offers compact and versatile MIMO test solutions with realtime fading including simulation of channel correlations.

This application note explains how to set up Rohde & Schwarz signal generators for 2x2, 4x2 and 2x4 MIMO tests with a focus on signal routing, synchronization of the generators, and leveling.

Please note that there is a successor application note available: 1GP97. It explains how to use the R&S®SMW200A vector signal generator for testing higher order MIMO systems such as 3x3 and 4x4.
