An analytical approach to compute the uncertainty of multiport scattering parameter measurements is presented. First, the various uncertainty causes from the noise to the standard definitions are modeled and characterized, then the uncertainty propagation up to the device-under-test measurement is computed. Experiments confirm the validity of this general approach.
