Abstract:
A vectorial network analyzer for analyzing a test object (DUT) having at least two measuring ports (1,2) to each of which, respectively, a separate high-frequency generator (G1, G2) is associated and whose measuring arms (Z1, Z2) respectively have quad gates (R1, R2) with associated measuring points (M1 through M4), wherein the high-frequency signals (f1, f2) of the high-frequency generators (G1, G2) are distinguishable from each other and are fed simultaneously to the respective measuring ports (1, 2), so that at an input and an output of the test object (DUT), which is connected between the two measuring ports (1, 2), respective complex reflection and transmission coefficients are simultaneously measured in forward and backward directions.
