9' leads? Those are transmission lines and there is no way to make them flat and high impedance w/o echos. You have to mentally subtract the echo's because they aren't terminated with the cables actual impedance. Even 30"ers can do that to you at the frequencies I play with. A 9 footer would have to have active electronics (power hungry and hot) in the hand piece to drive the low impedance cable, and probably a cable terminator hidden in the connector at the scope end of the cable. Last time I looked at active probes they weren't too far from a 4 digit asking price. Now, check ebay & expect to fix it. > Mark > > ------------------------------------------------------------------------ > ------ Cloud Computing - Latest Buzzword or a Glimpse of the Future? > This paper surveys cloud computing today: What are the benefits? > Why are businesses embracing it?
