I want to remove the effect of non-ideal switching effect from measurements. The following article discusses one simple technique to do this:
R. B. Marks, “Formulation of the basic vector network analyzer error model including switch terms,” in Proc. 50th ARFTG Conf., 1997, pp. 115-126.
However, the technique proposed relies on measured wave amplitudes of returned waves from the non-ideal Z0. For example, a3.
Now the question is. Is the N9918A VNA a three-sampler system or four-sampler system?? I do not get an answer to this from the manual of this VNA.
