Ernie,
There are many to choose from on FleaBay; search, '*nanovna vector
network analyzer calibration kit*'.
Yeah, some C USB cables are *data only*. Again, FleaBay can be your friend
(or your worst nightmare;
it's all about perspective). Try this one:
Take care,

Gentlemen (and ladies too, of course).
I¡¯ve had my NanoVNA since they first came out; I think a year or two. For
several reasons I haven¡¯t taken it out, nor even calibrated it yet. Now I
have the time.
Upon opening the plastic box it came in, I notice that I¡¯m missing one of
the calibrating SMA threaded resistors. Does anyone know where I could
purchase another set?
Second, I¡¯ve tried multiple charging cables; the ones with USB ¡°C¡±
connectors, and none of them will pass current into the unit¡¯s battery. My
friend has the ¡°sister¡± unit to what I have, and his USB cable works just
fine. Are there differences in those cables, or do I have two that are
bad? Where could I purchase another and be certain I¡¯m getting one that
works?
Any and all help in this regard would be most appreciated.
Ernie
