[Test-Equipment] RF spectrum analysis

[Brian Burns]

~ I think what you want is a network analyzer.  If you just want to see
magnitude of the response then a scalar network analyzer would suit you (or
a spectrum analyzer with a tracking generator or noise source). If you want
to see how the impedance changes with frequency and the input and output
impedances of a circuit then you may want a vector network analyzer.

What I'm mostly interested in is ham receiver design, building, and
alignment. So, that would involve looking at the passbands of the tuned
circuits associated with RF amplifiers, mixers, and IF stages, including
crystal or other types of filters. Perhaps 1 kHz to 100 kHz wide at a center
frequency of  around 2 mhz. Of course it would be nice to be able to look at
RF amplifier circuits at up to 30 mHz, as it's the good old HF region that
I'm interested in.

Cheers,

Brian
