Patent ID: 8508241

Claim:
A method for the calibration of vectorial network analyzers, which comprise n test ports, wherein several different calibration standards are connected to the test ports, and wherein n is an arbitrary number greater than 1, the method comprising: performing n calibration measurements by: connecting a comb-generator for providing a comb-generator signal, using a connecting line, successively to all n test ports, the comb-generator signal comprising a sum of several sinusoidal signals of equidistant frequency interval, successively measuring the phase of the individual signals of the comb-generator signal at the same time at a measuring point on the comb generator and at a measuring point of the respective test port, and determining a frequency-dependent phase offset of the individual signals from the measured phase values, and performing another calibration measurement by: terminating all n test ports in each case using known, identical, first input impedances of arbitrary transmission properties, and successively exciting all n test ports using a transmission oscillator successively with all frequencies of the comb-generator signal.
