I'm looking for a new entry level scope; 50MHz just won't cut it, and while I can make do with 2ch, 4ch would definitely help. I've developed many embedded Linux systems and the hackability of the firmware is a somewhat important deal for me as well.
I've read a ton here about the Rigols and the Hanteks and the Owons and the Siglents, and it seems to me that the Hantek seems to be doing a pretty damned fine job, with the exception of deep memory capture/manipulation. If I can hack on the firmware I might even be able to bring something like serial data triggering to the Hantek, which is probably the single biggest feature I'd be looking at Rigol for.
Here's the thing ... everything talking about customizing firmware and hacking the scopes talks about the Hantek DSO5000 series and never seems to mention 4 channels nor the MSO5000 series. I see lots of information suggesting that the MSO5000 series is literally the DSO5000 series with an additional digital capture board installed, but I've yet to come across a post or something on Google stating "yes I have managed to enable 200MHz bandwidth on a 4ch Hantek scope and here's how I did it" kind of thing. Ditto for firmware for the 4ch or MSO series.
Does anyone know if the MSO5054FG (50MHz) or MSO5074FG (70MHz) scopes can be hacked for 200MHz analog bandwidth, and if their firmware is just as hackable as the DSO5062/5072/5102?
