A friend has one. He's very happy with it.

One of the advantages of a PC based scope is that it doesn't take
up much room on your desktop.


But why are they so slow? At least the ones I have seen were. We designed 400MSPS converter boards even back in the late 80's and early 90's. It ain't rocket science.


The company I work for doesn't have much of a budget for test equipment, but we have a budget for boards (yeah I know) so I was considering making a pretty fast scope / analyser using a quad set of 500MS/s A-Ds and a couple of fast FPGAs and some memory.

It won't be perfect, but it might do the job and save 'that budget'.


That's a strange way of looking at the financial bottomline. Look at the (realistic) number of paid hours you'll be working on that one-off project and then compare that to a nice used Tek scope. Now copy your boss on that.

I have opted for the used Tek scope for my lab :-)


Oh I have tried, but he sees only the 'cash' movement, not the value movement (I would note I am not likely to be there much longer anyway)

I might do a combo scope / analyser just for giggles anyway.

Cheers
