NanoVNA Under The Covers Limited by the effective dynamics of SA602 and
AIC3024, external noise cannot be eliminated and NanoVNA can only measure 70dB
return loss.
It is very, very difficult to achieve at 70dB return at 500MHz, and nanoVNA can be measured only in dynamic range, not that the load can be easily implemented, but this is only an ideal situation.
