Hello Guys. First of all: I appreciate all your help!
I got 2 Voltcraft DSO-1062 Oscilloscopes in our laboratory at university and both of them share exactly the same Problem: They are always crashing.
This happens randomly but really often like every 5 Minutes or so.
Now I figured maby a firmware update could help. But since im seeming to be running on an old firmware 2.06.3 it looks like I cannot update it via usb. I tried several old usb-sticks just to make sure a bad usb stick is not an option. I always get the error code 0xff - no usb device found.
I've been searching for 2 days now trying to fix this thing but I cant find a way to update the firmware. I already tried to follow the tutorial from another post (
https://www.eevblog.com/forum/repair/voltcraft-dso-1102d/msg2036896/#msg2036896) but at one point I figured that the file structure of my oscilloscopes seems to be completely different from what he described.
I guess I, to all extend, already fried one of them because that thing is always rebooting without pause.
So I would be glad to get some adviced of what to do now.
Thanks in advance.
