Re: Back terminated cable?
Ah! I understand now: thanks.
I was thinking in terms of source - with its internal Z - connected to a 50Ω line - connected to a 50Ω spectrum analyzer. But with a chain of interconnected 50Ω modules, 'tapping off' at an intermediate point in that chain to a load (such as an S.A.) - which presents 50Ω to a source - is a different scenario. At that point of measurement, the source will indeed 'see' 50Ω||50Ω.
