The N5291A measurement solution for mmwave network analysis is a distributed system composed of a vector network analyzer (VNA), a test set controller, and frequency extenders. A distributed system is made up of separate components that communicate together to act as one system. The frequency extenders interface with the device under test (DUT) and are the only pieces of the system that operate at mmwave frequencies. This allows us to test mmwave devices without having to completely rebuild VNAs to handle higher frequencies. The frequency extenders connect to a test set controller, which interfaces with the test set of the VNA. This gives the VNA a new maximum frequency of 120 GHz so it can test modern mmwave devices.
