Hi Dislord
Thanks for response, but wondering why S11 impeadance measurement seems to include also port2 input measurement what can explaine this strange displayed impedance of port2 , i assume that S11 measurement should include only port1 measurement no matter what we have on port2 hardware, example an external frequency generator hooked there ... .
Not sure but i guess may be calibration calculation may mixe port1 and some portion port2 measurement , i dont know ??
