Hello,
I created a low pass filter in orcad and trying to put theory into
pratical. The circuit output is always showing the input at about one
third the pk-pk voltage even at 30kHz and more, this is suppose to be
a 3kHz lpf.. I think the wiring might be wrong.
I took the black pin of the function generator as the ground reference
point. Use two 6v batteries for positive and negative voltage and
place the middle of the batteries at the ground reference point from
the function generator.
Here is a link with my circuit and a picture:

Or does any one has a specific instruction to a simple active LPF and
wirinf connection, maybe I can start from there.
I tested my OP Amp, and that is not the problem.
