I was hot for the Tiptop VCO till I saw this video made about it.

That is one of the worst sine waves I've seen and the spectrum display
shows many harmonics that shouldn't be there. I count at least 7 on
the spectrum display. . All I can hope is the distortion is caused by
something downstream between the VCO and the scope. Does anyone who
has a z3000 and a scope and can tell me if this setup was just faulty
or does the unit make sines as shown in the vid The other waveforms
shown are not to good on this demo either - the sawtooth and triangles
look like they sag and the square waves are not square with flat tops
and bottoms.
