Hi,
The sine waves in my XR2206 IC function generator started at 3 volts and varied from there to 5 volts and 1 volt.
In ordinary function generator equipment. Is the sine wave at 0 volts and rising/falling from it or does it also start at higher voltage as base?

My function generator allows me to offset the signal by a variable amount, both pos. & neg. I think it may be based on the XR2206, but I'm not certain.

It depends on whether the designer made it one or the other. If the output is couple with a capacitor there is no DC offset, so the sine wave varies around 0V. If a DC offset is superimposed then the output will vary around that.

----------- Put it through an inline capacitor and it will be referenced to 0 as long as it is a sine and is buffered by an amp after it. Then you can add an op-amp adder stage to add any DC offset to it that you wish.
