I don't know, it seems like it is severely limited by the embedded processing power available back then, and that a more modern CPU and FPGA combo could really make difference.
Honestly though, I love this scope so much just for the extra bandwidth that I'm reluctant to mess with it.
No, I don't have any options on this scope, which is why it was so cheap. LeCroy still wants real money for the options. Not UNREASONABLE money per se, just too much to put into a scope that could fail at any time.
I would love to have that jitterpro option for an upcoming project, and I may just have to buy it.
Yes, the rotary encoders are handled poorly. Mine were actually worn out to the point where they really barely worked at all. After I replaced them, they worked perfectly, but they were still very slow to move the cursor. This appears to be just how they are coded. It's a giant pain.
There's a single 68K (I think) microcontroller on the front panel board, if I remember right... Chances are decent that the encoder acceleration is handled within and could be tweaked without messing with the main CPU board.
LeCroy customer service emailed me the service manual just for the asking. I will check and see if I am allowed to share it. Or you could just ask them and they will probably just email it to you.
