I do not have one. If it is going to be needed I can look into getting one I suppose. Any specifics I would be looking for?

Ok you got that Hantek 2D42 scope right?

You know what, maybe we can do a skype session, else it will take to long. Also then I can see what you measure, and I can tell you where to measure. And when we solve the problem we can put the problem and solution in this topic.

So send me an email to see when we can do this.

From what I can see it should be on par. The highest frequency in the mp-1 is 12MHz.
