Problem solved Thanks. Yes I was reading from the virtual channel. If I had paid better attention I would have noticed that the Test panel in the virtual channel setup says average value. The solution is to take an average. Here is the Fix. Put the Sample Channel VI in a forloop. Out side the loop use add array then connect to Divide symbol. Create a constant in the for loop N of 200. The divide constant must match this number. The higer the number the more noise it removes. Basicly what you have here is a software signal conditioner to a point. It works very well. If you want to see the effects build a VI using random number Zero to one. Wire a Control knob to the divide and forloop N. Note that the zero to 1 stays with in a range of .4 to .6. Basicly it takes an average.
