@AnarchistWolf, for your information, I also capture the screens of my SDS1204X-E, not hacked and with the latest software version (R9), every second with a USB connection. The longest capture lasted around 30 minutes and the screen never froze.
Previously I had a DS1102Z-E that I do not regret...
Have you tried the scope's built-in web server? the capture frequency is very high.
