[sdiy] Cheap audio spectrum analyzer.. finally..

[Sarah Thompson]

The 35660 is a significant boat anchor -- it's the biggest and heaviest
thing I own, though it's fighting that out with my big Tek logic analyzer.
Works awesomely well, though and I wouldn't want to be without it. I'll
second the usefulness of the chirp signal. I have also used the 35660 with
a signal from an arbitrary waveform generator, which also worked but I
can't for the life of me remember why I needed to do that at the time.
