Hi Fermiguy,
I saw the VI that you are talking about showin in pictures in the manual for the Instrument Simulator. I couldn't find a VI that did this, so I created one that should do the same thing. I'll attach it to this post. It's fairly straight forward. Just supply the string output coming from your Visa Read or GPIB Read and use it as an input to this VI.
