Hi,

I noticed that under VNA Device has Unknown Error Terms part. What is purpose of that? Similar thigs are already defined under Drift window or not so?

Hi Tuomas,

the unknown error terms are only needed for incomplete calibrations, e.g.: reflection normalization, transmission normalization or one path two ports.

Hi,

Are these unknown error terms always included in the calculations?

Regards

Hi,

No just for incomplete calibration:

- ReflNorm

- TransNorm

- OnePathTwoPorts

Regards

Michael
