Technical and scientific discussion of amps, cables and other topics.

RE: That's very interesting!

"So what frequency cleared up the wooziness?"

I don't recall exactly but it was in the direction of the nominal frequency, maybe about 1 Hz.

"how finely can you tune the thing?"

Well, I didn't know so I just tried. It's an old analog Fn Gen. with an internal counter having 1Hz resolution in the 2-20 Hz range. But it looks like you can get 0.1Hz deltas fairly well if you use an external counter. The limit is just the resolution of the single turn pot which covers a decade of frequency along with the patience of the shaky ol' knob turner. I didn't assess drift but I suspect it's OK after a warm-up.
