Re: Wrong cable... How bad is it?
Mia culpa for a few errors,
To Dave Brown, sorry for my Poor mémoire on the RG numbers...6 vs 8....
the Tektronix précison cable for SG503 is not 1/2m but 36"
Special double braid cable and specific precision BNCs.
Look on epay and ham fleas....
Years ago I bought a bunch new in original tek packing from an ex Tek engineer.
Dennis had made fine TDR measurements on several cables in this thread,
