I have an HP 3312A function generator for sale. I was going to repair it, but I need space more than I need another function generator.
It powers up, but the waveforms are not right. I don't remember what exactly the problem was, but have not had time to check.
I've not cleaned it and it has that old HP sticky feel, if you know what I mean...
$30 plus shipping - US only.
Thanks,
John
