Your vi won't load on our machines without the TDS' driver. If you "Save with options" as a "Development Distribution" it should include the required sub-vi's. The be sure and "zip" the resulting .llb file to reduce its size.

happybird,

I'm not going to be of much help since I don't have access to your instrument. Does one of the getting started examples shed any light on this? What exactly are you trying to accomplish?

Here is an example of how I read data from a yokogawa dl708 scope.
