David,
Could you give the group a short form on how this is done, and what a
NanoVNA user would do and see to measure something like a piece of RG6 or a
75-300 ohm transformer? Not to take away from your sales, but what kind of
error would a pad made from 1% carbon resistors introduce, compared to a
commercial pad?
I don¡¯t sell 75 ohm kits, neither do I sell matching pads - only 50 ohm
kits and consultancy services.
I heard a report somewhere on here that the receiver port on the NanoVNA
is not particularly close to 50 ohms and varies on the batch a given device
is from. That¡¯s something I would like to fix myself, which could be done
with a few 1% resistors, after measuring the impedance.
