But thats a Tek, its waaaayy old, and according to the link, a box of parts. He needs something that Just Works, not a service engineers worst nightmare before he even gets back to thinking about his problem. I have long time experience with 2 different Hitachi scopes. You turn them on, and they work. Those Tek things were great when A, they were new, and B, in an R&D lab. Tek today is a far cry from the Tek that impressed the hell out of me in the early 60's when they had a lifetime warranty. But now they clean out the parts crib 30 milliseconds after the federally mandated 5 years support period has passed and beyond that 5 years there is NO support. Heck, for this job, one of the DS-2O1's would work, but he would have a far harder time learning to use it with its limited controls that do everything depending on the mode its in, and its bandwidth is such that it would miss step pulses, confusing him. He isn't familiar with a "scope" at all I suspect, so he needs something where every knob does exactly what you expect once he learns what to expect. The phrase Just Works keeps coming to mind. > > Then he can start collecting all the neat plugins too. ;-) > > Mark > ------------------------------------------------------------------------ > ------ LIMITED TIME SALE - Full Year of Microsoft Training For Just > $49.99! 1,500+ hours of tutorials including VisualStudio 2012, Windows > 8, SharePoint 2013, SQL 2012, MVC 4, more.
