Abstract
A system for determining scattering parameters of a frequency-converting device under test using a network analyzer determines the system errors which occur between the individual ports () of the frequency-converting device under test () and the ports () of the network analyzer () connected to the ports () of the frequency-converting device under test () and measures the system-error-containing signals incoming and outgoing in each case at the individual ports () of the frequency-converting device under test (). Following this, system-error-adjusted signals incoming and outgoing in each case at the individual ports () of the frequency-converting device under test () are determined by weighting the system-error-containing signals incoming and outgoing in each case at the individual ports () of the frequency-converting device under test () with the associated, determined system errors, and the scattering parameters of the frequency-converting device under test () are determined from the system-error-adjusted signals incoming and outgoing in each case at the individual ports () of the frequency-converting device under test (). The phase of the signal to be measured exciting, in each case, a port () of the frequency-converting device under test () is initialized in an identical manner in every measurement.
