I opened up the attached ps3000.vi, uploaded on Nov. 16th, but I'm not quite sure I'm using it correctly. After I changed the names from the ps2000.dll library to the ps3000.dll library, it seemed to open fine. When I click start, although the graph is updating itself, it doesn't seem to be moving along. In other words, if I touch the scope probe to a signal, the first point moves up and down, but the rest of the line stays flat. I messed around with the no. of samples and the voltage range and things, but nothing seemed to help. Is this just a simple issue I'm missing or is something larger going on?
