Hello!
I am afraid that I don't fully understand what you are asking for. You have two programs that are controlling the very same instrument through the same GPIB controller, is that correct? What address does MAX says the instrument has? Which programming environment are you in? How do you set up the addresses for the instrument?
Just questions as you see but I would like to get a better understanding of your problem!
