I have seen latest Version 2.5.7935.30849 can support Frequency Conversion Calibrations(3.9.1 Scalar Mixer) , Unknown Mixer(3.9.3), but had not explained the equation and had not given References. Are unknown mixer calibration the same with ZNA's K5(Vector Scalar Mixer Calibration)? This function asks VNA's source port have coherence with each other.
Can you give detailed theory?
And when will METAS support noise figure evaluation?
