Hi guys,
i know the main function of a network analyzer is not to measure impedance, but i still have to rely on it since i dont have a impedance analyzer.
i read in many notes and some text book, that from a 2 port measurement,
the B parameter is the series impedance.
https://www.google.com.my/url?sa=t&...uKIGfD3znSpBiyBeg&sig2=EuvqaxUuefAlMXgqaSyUOg
unfortunately most books describes the relationship between abcd parameters and impedance very briefly.
This note above, in slide 20, it says that the B parameter is obtained when port 2 is shorted. this is not mentioned in other notes.
i would like to know more in detail about ABCD parameters and its relationship with impedance. and is port 2 really needs to be shorted?
if you know more about topic, please enlighten me.
or more directly to solve my problem,
what are the most accurate way to measure impedance with VNA?
thank you very much.
