Sounds like a the problem with your NOP card. Either the one I
mentioned in my other post, or some other problem. Is the
"unstable signature" led lit or flashing when you take your
measurements? I seem to recall seeing incorrect signatures
when I used the NOP method.

This also points to your NOP card, because the mathbox doesn't use
any signals from the NOP card when in SA mode.
