Dana,
Indeed, and for that reason I measured the same cables with the same calibration kit on thee different VNA's. (one the nanoVNA)
The results from the 3GHz VNA convinced me the fluctuations seen at the nanoVNA where not originating from the cable as such.
If this is a a wrong assumption I'd welcome an explanation to avoid I'm chasing ghosts
