Re: Phase of very high quality N short


 

Links within the FAQ now work. thanks!

I could understand the results shown in that FAQ
if the VNA is calibrated using one set of O-S-L standards
and the VNA is then used to measure the open and short standard
from some other calibration kit.

But if the VNA is measuring the standards to which it was calibrated,
should it not show the Smith chart at the top of the FAQ, with three nice clean dots?
