Thanks for the replies!
Actually My spec an has a tracking gen which I normalize.
I noticed after doing a cal on the nanovna and nanoVNA F that there is a 2 to 3 dB difference in the measurement.
Used the same cables and the frequency was 6.5M to 14.5M on both
RBW was 3 KHz
I know the spec an is good.
I was curious if there is a way to adjust the Nanovna calibration to reflect the same value.
