ABSTRACT:
To measure the effective directivity and/or the effective source port match of a test port of a system-calibrated vector network analyser, a precision air line short-circuited at the outlet is connected, and the complex reflection coefficient is measured at the inlet of this precision air line at a sequence of measuring points within a predefined frequency range. At the same time, for the effective directivity the sequence of the measured complex reflection coefficients is subjected to a discrete Fourier transformation and the baseband filtered out of the spectrum thereby formed. The sequence of effective directivity values is obtained by subsequent inverse Fourier retransformation.
