Active components, modern modules, CPEs, smartphones, tablets or any other wireless device support a growing number of technologies
and frequency bands. As a result, more transmitters, receivers and antenna paths must be tested in R&D and during high-volume mass
production (MP). The R&D engineering validation test (EVT) and design validation test (DVT) phases require more extensive RF testing
than mass production e.g. verification of MIMO performance and all supported bands and bandwidth combinations.
