Low Cost Frequency Response Analyzer

frequency response analyzer

Dear all,
I'm searching for some document, paper, thesis, about the subject, if someone can help me I'm gratefully.

I like to check if there is a way to build a simple analyzer from 0 to 1 MHz that can be used to test the loop gain of a SMPS circuit. I'm not searching to build a professional instruments (there is from 4000 $ to 15000 $, e.g. from Ridley) but I'm searching how to do some simple one (e.g. by using DSP and FFT algo) in order to have some didactical useful circuit.

Thanks in advance

Bye
