I should add, that after a calibration with their standards, the resulting

have to pray that a set of APC-7 or my sophisticated cal standards could do
so well. That said, this is a neat box and applying a little care to the
measurement and compensation for the short comings can rectify some of
these issues.
I'm afraid to say you are stepping into the error many people make. They
first calibrate with a set of standards, then see those standards look
perfect on the Smith Chart. I have hayfever at the moment, but made my
first YouTube video yesterday to show the problem.
Please ignore the sniffles I have and the fact I only used a mobile phone.
