Using nanaovna-saver, on a -f, I noticed that sometimes the circle on the Smith machine (on a simple capacitor, for example) could be larger than the grid circle.
Now, systematically, even before calibrating with nanaovna-saver, I perform a RESET on the case, which nanovna-saver doesn't seem to do (0.3.8 because W7). This RESET solves the problem.
