MIMO and beamforming applications require special consideration
Leading-edge test and measurement solutions from Rohde & Schwarz meet these requirements
The RF system in multiple input multiple output (MIMO) and beamforming applications requires a standard, good RF performance, and the following also need to be considered:
- Phase control, phase stability over time and temperature control
- Synchronization in time and signal, transit time of the various paths
To translate this into practical testing needs, best practices include:
- Locking and controlling the RF phases between test signals in different paths
- Ensuring accurate time sync between different channels for receiver testing
Rohde & Schwarz signal generators provide full control of coherent, time-synched signals in an easy and stable way.
