Re: Which Vector network analysis book to buy - help
|
Here's an image of the relevant page from edition 1. The offending line seems to be "And it is common to refer to S11 informally as the input impedance of the network". For what it's worth, I'm not a fan of that line either, but I'd be curious to hear what Joel says about this statement.
The exact same statement is made in edition 2.

Frankly, I don't see that S11 statement as an error. While technically, S11 is the measured reflection coefficient, it is that value which is used, along with the system characteristic impedance, to calculate the device impedance. So when Dunsmore makes that statement, he is simply jumping over the intermediate calculation step to point out that S11 gives you Z. In the context of the discussion, this does not seem to be an error, but rather a bit of enlightening illumination in case the reader has not yet made that small leap.

Thanks David - I will probably buy the HP book first and then see if I?
still have interest in the R&S book.
I am concerned about the error concerning the definition of S11 - does?
your copy have that error (which edition is it) ?
Cheers!
