Thanks for addition to my circuit. I tried it out and unfortunately the results don't seem to make much sense. The amplitude part works perfectly. The phase, however, jumps around and is consistantly too high in value.
Presently I am inputing a 4v sine wave @ 1 khz. Channel 0 is directly from the function generator. Channel 1 is thru an RC filter. The output at 1khz should be -45 degrees. I am consistently seeing phase numbers like 136 or -223 degrees. Is it possible that there is a 180 degree phase shift added somewhere? Thanks again for your help Dave
