Dual Band Measurements with a 4-Port VNA

This application note will outline proper setup and measurement procedure for performing dual band measurements with a Copper Mountain Technologies 4-port Cobalt VNA. This example setup features a C4409 4-port 9 GHz Analyzer and uses two ports for measurements in a low frequency band, while the other two ports are used for measurements in a separate, higher frequency band. Measurements with this dual band setup are not simultaneous but allow the user to quickly switch back and forth with the simple click of a button.
