An overview of the number of wireless devices, the diversity of communication standards, and the complexity of modulation schemes are increasing every year. And with each generation of new technology, the use of traditional technology to test wireless equipment, the need for a large number of more sophisticated testing equipment, the cost is also increasing. The use of virtual (software) instrumentation combined with modular I/O is a way to minimize hardware costs and reduce test time. A new approach to software design instruments allows RF test engineers to reduce testing at multiple order of magnitude without the need for custom or special standard instruments.
