Thread: Mini oscilloscope and function generator

    Re: Mini oscilloscope and function generator

    I would also like to put in my plug for Saleae Logic Analyzers. I have a few. Started off with their Orginal, then later purchased a Logic 16, as there were a few cases where I wanted the extra inputs but also more importantly the extra speed. I know have one of the new Logic 8s, with Analog input. Works well, still on a rare occasion I wish I had a proper scope. (I do have one of the really really old Parallax digital scopes from their earlier tutorials), that can sort-of work, but I have not dug that back out for a year or two...

    I also have I think it is one of these: https://www.sparkfun.com/products/11643 bouncing around here some where. But have not really used it. I tried playing around some with it awhile ago, but I think I would require some very strong magnifier to read anything on that display...

    Does the Analog Discovery actually stream logic capture data to the host in real time?
    With a 16k samples buffer, that would be very helpful!
    I think the 5 MHz analog bandwidth might be limiting if treating digital signals as analog?
    I like the claim of 14 bit resolution.

    The digital is 100MSPS. Don't know about the other questions...but given that it's USB2, it can't be a raw stream regardless, as 100MSPS over 16 pins is 200MB/s, way beyond what USB2 could support.
    The manual is here:
