Network Analyzer

The vector network analyzer (VNA) is a form of RF network analyzer widely used for RF design applications. A vector network analyzer is a test system that enables the RF performance of radio frequency (RF) and microwave devices to be characterized in terms of network scattering parameters, or S parameters. The information provided by the vector network analyzer VNA is then used to ensure that the RF design of the circuit is optimized to provide the best performance. Using an RF network analyzer in any RF design provides the RF design engineer with a view of the components and circuits that would not be possible with any other form of test equipment. In this way the vector network analyzer, VNA is an essential tool that RF design engineers should be able to use.
