Analog break out problem.

[Al Skierkiewicz]

Gary,
If as I suspect the 22 ufd cap, C10 is missing, then the regulator can and likely will oscillate. The addition of your 10 ufd then is merely returning some of the needed capacitance to the output. You will need to keep the noise filtering in Labview. There are two noise problems you are dealing with, the noise normally found in the sensors you are using, and that generated by a defect in the power supply. The reason I am concerned is that adding caps to anything except motor leads is not allowed in the rules. Repairs to electrical components are allowed so I would want you to get this right so you have no problems in inspection in a few weeks.
This is assuming that your load is less than the 500 ma the power supply is capable of providing.
