i have a brainfart moment trying to get this right... simple question at first is...
1) what is this for? (1st attached file 1v.jpg... i have s1p files for my cal kit all right, but...)
2) when should i leave it as in 2v.jpg? (parms = ideal)
3) when should i leave it as in 3v.jpg? (parms = set to corresponding s1p files)
to get the idea what was wrong...
- i made calibration with parm set as ideal ie 2v.jpg and got saved into a cal file (lets call it calibration 1 or C1)
- i made another calibration with parm set as in 3v.jpg using s1p files set and got it saved (lets call it calibration 2 or C2)
and then when i do real measurement i will get wrong answer (graph plot) if i leave the setting as in 3v.jpg and load either C1 or C2. i can only get correct plot if i leave the parm as ideal (2v.jpg) regardless if i load C1 or C2. i thought we should always set it to the cal kits's s1p files and then load the calibration file (regardless C1 or C2) to get correct plot.. or to be more logical... if we set to ideal cal kit parm, only loading the C2 can we get correct answer... correspondingly, if we set the cal kit parms to cal kit's s1p files, only if we load C1 then we will get correct answer, not the other combination. but i dont get this logic on my VNA View (PC SW) screen. this is brainfart...

please explain to me.. thanks.
(ps: this was not an issue with my KC901V VNA since it doesnt support loading cal kit's s1p files into calculation)
