The engineering man hours that go into deciphering this garbage are probably worth more than buying a proper scope, like a Keysight. Too bad I'm not being paid.

It's 5pm, time for breakfast. Haven't eaten anything all day. The only thing I consumed was coffee, lol.

Actually, forget eating. Who needs food anyway? I pulled this thing out of the uni ewaste bin and never tried it out. Guess it's time.

After compiling and installing kernel modules and libraries from outside my repository (that's always fun), I get this.


Here is all the stuff needed:

When talking to this thing.

So a quick summary: The scope recognizes it's being talked to and I can see it on the PC side. However, I do not know which commands this even supports. This is probably pre SCPI standardization. I also do not know if the GPIB to USB adapter nor if the GPIB functionality of the scope work. So far I have not gotten it to react to any command or send any data to the PC.

I suppose this has to wait for now. Need to try with a different GPIB interface and maybe tap into it with the logic probes.

It works!!

Love how my 2018 scope can not only trigger on analoge video, but also a specific line
