That Spec Anny sounds interesting. Are you trying to
have one operate on a computer? Or are you trying to
make a smaller version?
It is a modification of the Spectrum Analyzer from Kanga US
http://www.bright.net/~kanga/kanga/w7zoi/products/spectrum_analyzer.htm
I am limiting the bandwidth to 4 MHz and the range from 144 MHz to 148 MHz.
The plan is to use 12bit D/A to control the VCO of the 1st LO and 12 bit A/D
to provide the results.
The original bolted to an Oscope for visual information. It also has a log
amp output.
This way if time gets short, I'll just use a voltmeter for results.
I plan on posting a small progress page with pics and notes. Maybe
tomorrow???
This is old school SA work. The new/state-of-art method is with this group:

The yahoo group for this project is:

That's enough to chew on for a while. <grin>
Believe me, once this school stuff is done with, Ezuki progress can be made.
I actually considered doing a system controller for the Ezuki as my senior
project. I thought about letting the Palm
idea act as the front end, but the math and complexity of the SA project,
along with the fact I could carry it to class, made it win out.
