I repeated this Calibration/test a number of times today, but I just did it again with the same results.
Lets say that I am Calibrating/testing correctly, so on the Open/Short tests, regarding the LogMag results, VNA #1 or #2 or Both are correct?
what readings do you get for all three terminations *without calibration*? - the NanoVNA isn't perfect, but you should get close to 1, 0, and -1 for the reflection coefficient.
And between two units, you'd expect to see similar values.
