Hi Fabio,

Best of luck! I believe you'll get good results. Don't be disillusioned if initially things seem unpredictable or varying, because often just the cables moving can be enough to make a difference : )

If you can, keeping the coax position the same so that it doesn't move between measurements, could help. And double-checking that the connector on the other end doesn't accidentally become loose when unscrewing/screwing the opposite end.

Also, running the calibration procedure each time you sit down to start your tests (with the calibration done on the end of that cable, with the cable at the same position it will be for your measurements).
