There¡¯s a few references here.
Application notes 3 and 4 are particularly informative on this. Generally
the Keysight application notes are useful.
Great set of references. In addition to Dave's HP application note links, there are more here: .
The 8510 documentation is especially worthwhile because its UI seems to have been one of the main inspirations behind the NanoVNA, or at least the -V2 model. Even better if you can track down the training seminar binder that HP provided to 8510 customers. I've never seen a .PDF of that one, which is a shame.
The book by Dr Joel Dunsmore, who is a Keysight employee, is quite
informative, but is heavy going mathematically, and a typical price of a
professional text book - ie 2-4 times the cost of a nanoVNA.
Joel's book has a brand-new 2nd edition, 25%+ longer ( ). I wouldn't say that it's too mathematically-heavy, just that the math is there for those who need to delve into it. Nice resource for anyone who has either progressed beyond the initial fundamentals or would like to do so.
There is a similar book from Michael Hiebel of Rohde & Schwarz ("Fundamentals of Vector Network Analysis", ). Fortunately there are used copies for sale at less than the $375 quoted for a new hardcover. You probably don't need both the Hiebel and Dunsmore books, but if you're interested in this stuff, you should own at least one of them IMO.
