There are some very good applications notes available, especially the old
HP ones. They are a lil more advanced though and expect a decent level of
maths...
S-Parameters
http://hpmemoryproject.org/an/pdf/an_95.pdf
http://hpmemoryproject.org/an/pdf/an_154.pdf
And the updated Agilent versions of them:

Spectrum Analyzers

http://www.ab4oj.com/test/docs/sa_fundamentals.pdf
Network Analyzers

I also really like this book as an introduction to RF measurement devices
and techniques:

I created a page on the wiki with some learning
resources for getting up
to speed on the work we're starting to do on antenna design and impedance
matching networks:

Since we'll need a VNA for this work I included a comparison of different
affordable VNAs.
Tomorrow evening we'll probably spend some time building a simple test
setup with two computers displaying the RSSI from the RFM95 modules.
