Problem solved
Hi, Today i fixed the problem in several different ways. First of all I made a mistake in my original post. The Noise is not +- 2.5 mv ( that would be extremely small if that was the case and i wouldnt have any problems. The noise level was at 200 mv which was causing me problems. After wiping out the Megaherts and Kiloherts interference with the Low pass, I ended up with
'2' 60 Hz noise signals superimposed ( since i am using 2 power supplies) with a level of 60 mv which is much improved. Well I built a Notch filter at 60 Hz which basically wiped the interference clean, but then i decided to use Batteries instead of power supplies, since i am only drawiing 2 ma at 24 Volts (1.3 AH) these batteries should basicaly last forever. I have a beautiful clean signal on the scope. My ATD readings are perfect. I cant believe i dragged this on for a week before fixing it. Thanks for the suggestions and the help.
I did not use a Scope in the begining, I was using my digital readings to try to figure out what was going on and thats what screwed me up.
