In an attempt to sum the outputs of two function generators (50ohm and 600ohm) I made this circuit based off of a design from http://www.ti.com/lit/ml/sloa091/sloa091.pdf pg A26.
-I went with buffers to negate the impedance mismatch of the generators and set my resistor values to 10k as per the design example.
-I tried to incorporate a potentiometer to set the offset votages to the i/p and o/p stages so that the inputs be purely +ve voltage (single source) and the output could be adjusted through measurement
-In reality this potentiometer has done little
