Hi Seb, I bought my old analog, 20 MHz dual channel scope over 20 years ago and am thinking of something to replace it. Based on my experiences, my wishlist is:
- At least 20 MHz. 20 MHz is pretty low (cheaper), but in most cases enough for IO- and power-related issue's. - dual channel - cursors to measure (that's a comfort i'm lacking now) - storage fuction - able to record and show a single shot But I also 'need' a logical analyser every now and then - some cases require to monitor up to 4 (mostly digital) signals at the same time. And combine a analog DSO with a logica analyser would be ideal. But... these are extremly expensive unless you get an usb-device and use your computer - then they are just very expensive. And I am not sure it is very handy that you need your Windows pc for this... Take a look at: http://www.dynoninstruments.com/products_s2x100.php for a 50 MHz usb scope for the same budget. (I have no experience with these products, just looked at the specs.) Digital interfaces (like SPI and I2C) tend to get faster and will go too fast in a couple of years. If these don't work like they should, you mostly need a protocol analyser (logic analyser + sw) and only in rare cases a DSO. So to answer your question: I think a 20 MHz dual channel DSO will do for most of the cases...
