MIMO Test

As a world leader in test and measurement solutions, Keysight Technologies continues to be at the forefront of emerging markets such as MIMO (Multiple Input, Multiple Output). A challenging antenna technology, MIMO ultimately will improve spectral efficiency (bit/sec/Hz), signal quality and cell coverage. But being an evolving standard, it provides hidden roadblocks and requires a new suite of measurements. Our engineers, experts in test and measurement, are making the new measurements easier for you to analyze and troubleshoot your system. From R&D through integration and manufacturing, Keysight has test equipment to provide insight into these complex signals and allow you to meet your time to market goals.
