FYI: not too impressed with the software quality. In the space of one day, I have had the DSO5062B freeze and then do a BSOD and reboot, the TTScope app running Virtual Panel never runs for 24 hours without a crash, and when I turned off power to the DSO while it was connected to PC by USB, it caused the PC to BSOD. The PC did its memory dump and then it sits there, have to manually reset the PC. Sometimes I use VNC to connect to this PC from a remote location. I have no way to reboot the BSOD'd PC remotely, so this is really bad news. Not that it should matter, but the PC is running Windows 7 64 bit with all updates and everything else on the PC is rock solid, it's on 24/7 and never crashes. If I can see a pattern I'll submit bug reports, but so far the Hantek crashes in firmware/USB/TTScope look random.
