How to Characterize Multiple-Input Multiple-Output RF Behavior

Measure Multi-Port Multiple-Input Multiple-Output Behavior

Characterizing multiple-input multiple-output (MIMO) behavior in production requires signal generation, capture, and analysis across several RF paths while maintaining repeatable timing and port configuration. The test sequence compares signal quality, output power, modulation behavior, and port-to-port balance across antennas or streams, so the device under test can be evaluated as a multi-path wireless system rather than as separate single-port measurements.

The measurement setup captures signals across the relevant ports, applies the selected wireless analysis, and compares stream-to-stream results to identify imbalance or variation. A practical implementation supports switched MIMO testing, scalable transceiver resources, and enough RF connectivity to characterize 2x2, 3x3, or 4x4 wireless local area network device behavior on the same production-oriented platform.

Multiple-Input Multiple-Output RF Characterization Solution

Characterize MIMO RF behavior by capturing wireless signals across the required ports or streams, applying modulation and power analysis, and comparing results across the full multi-port configuration. The solution uses a Keysight Wireless Test Set for wireless device manufacturing test, with up to four transceivers, vector signal analysis, vector signal generation, and four-port RF input/output connections. It supports wireless local area network measurements with 2x2, 3x3, and 4x4 multiple-input multiple-output configurations, including switched multiple-input multiple-output for manufacturing test. This enables repeatable characterization where port density, stream consistency, and production scalability matter.
