Abstract

A vector network analyzer is provided which includes a first measuring port, a digital interface connected to the first measuring port, a second measuring port adapted to be connected to a radio frequency (RF) input or output of a device under test (DUT), and a processor. The digital interface is adapted to be connected to a digital input or output of the DUT. The processor is adapted to determine scattering parameters (S-parameters) of the DUT based on measuring signals transmitted to the DUT and received from the DUT by the first measuring port and the second measuring port.
