A great read if you are 1) considering a new DSO or 2) playing with ADCs

Yep, I am still playing around with ADCs/DACs etc on the propeller. Have not pushed above 100ks/s yet but soon, soon. Question is how to do it. Also, working with a couple of ebay'd tektronix scopes including a 2430A. Nice one, but some damage to one channel, and the chip has been described as many others as well, pure unobtanium. The CCD chip. Any way, came across a very interesting article that anyone considering a scope now should read and be aware of. Or if you are playing with the idea of interleaving multiple ADC samples to get higher sample rates this applies there as well.

Interesting reading to be sure.......

    Frank, when I got my 2430A it had channel troubles too. It turned out to be the attenuators. It seems the relay contacts in the attenuators get dirty. After cleaning the attenuators with anhydrous alcohol the scope worked great.
