VERY TRUE The larger the hardware errors, the larger the errors that need to removed so the accuracy of measurements suffer with the slightest change in temperature. Adapters with a poor return loss BEFORE the calibration plane can still cause problems with stability of measurements. Despite error correction, it is not uncommon to do things like improve the match at test ports with attenuators. I think it would be unwise to embark on designing a VNA unless one has at least used one first. I don't think designing a VNA is the best way to get one. Perhaps after buying one (8510 or 8753 is probably best) then designing one is likely to be more productive.
