[sdiy] Retarded function generator - Agilent 33220A

[Charles Bisaillon]

Hi, I would love to get your opinion on this one,

I remember having unexpected low level problems when we were presenting the
capstone modular project. Well, I recently learned from a classmate that the
function generator I used to design the whole synth actually outputs twice
the voltage selected. I remember setting it daily to 10Vpp and using it
instead of my 10Vpp VCO. I went back to check verify this and he was right,
set at 10Vpp, I get 20Vpp at the output. How can someone design such a
stoopid thing?

Anyways, this means that all of my module's inputs, unity gain, clip
circuitry, headroom, etc, are designed to receive twice the voltage that
they will operate on. On the other hand, all my outputs are designed
properly and yield proper levels (provided you get a proper input, which in
this case is 20Vpp). It's such a pain, even my 1V/oct is actually designed
for 2V/oct...

I now have a choice to make: Raise the VCO outputs to 20Vpp instead of 10Vpp
and the ADSR to 10V instead of 5V, or go back to the breadboard and redesign
the VCF and VCA? I would love to get your opinions on this.

Thanks
