Dave, Thanks I appreciate all you and Darrel are teaching me and not getting to stressed with me while I try to learn this. I'm going to work on capturing the wave this evening and take a look at what I see. I do have the components that Darrel suggested on order as well I want to hook those up in any event to help me understand. Things are so much easier when the device is DC like they were with the pressure transducer.

thanks again
David
