I caught in a trouble on the wrong wave form of function generator with XR2206.
The wave form is cut by half.
Is there a way to fix it?

 

Did you build the XR2206 from a kit?
If so, double check all the parts for being the correct type and value.

 

Use the circuit shown on the datasheet:

I have bought it on Amazon preassembled kit.
and then I have modified it for the my experiment purpose before restoring it the original state.
So something may go wrong the arrangement of components.

If it worked in its original state, and doesn't now, that obviously it's not back to its original state.

 

BTW that poll you started prior to the OP makes no sense for the type of problem you need to solve.

Buena suerte.

 

Resoldering it many times would have broken the circuit patterns.
It may be a cause of wrong wave form.

So I decided to buy a new one on the web, then the old one is used as a spare for components...
