I am using the AnalogOut on a Panda II. I need to generate a 0-200mv signal. The lowest output I can achieve is 40mv. Is there some kind of limitation with this port? I have the most basic program using the port and setting the linear scale from min 0 to max 3300. If I set the output to Zero, I get 40mv instead of near 0. I get 3.3v at max which is what I expect.
