Thanks for watching! - Věda a technologie
thanks
Nice, so much easier to watch this than follow and figure out the forums!
Many thanks Mark! After watching, I'm looking forward to finally buy that oscilloscope.
Done! Thanks!
sweet - will give this a go.
Nice! I don’t have one of these ‘scopes, but it’s good to know that if I ever get one I’ll be able to hack it.
I think, there is also a hack for upgrading the bandwidth etc. for the Rigol 1054. when I have bought my Rigol MSO4024, I had got the license files for upgrading the bandwidth and all the serial protocol decoding as a free extra with it.
Yeah the 1054 had similar hacks available. But I think rigol started including those features free of charge later in the 1054 lifespan
thanks great video would you be able to make a video of how you hack the dp932e to the A version
Hello Mark, after you did the first upgrade in the first video and all was well, had memory and bandwidth and it worked fine. Mine also worked fine, after updating the firmware to 1.2 all was fine still had memory and bandwidth like in your second video, But after I recalibrated it was all gone and still have 1.2. In your second video after the firmware upgrade to 1.2 never saw you do a calibrate, which on my scope removed the memory and bandwidth. Have you recalibrated after the latest. In short after the firmware upgrade to 1.2, memory and bandwidth still good until I did a calibrate
Ah, no I didn't do a calibrate after updating. I probably should do that, it's been a while
What does the bandwidth option actually unlock if my DHO-804 can already display 250 MHz signals? Does it allow higher zoom? Or is the amplitude more linear (removing software-controlled 70MHz filter)? Just curious. :)
From memory the max zoom on the 804 is 4ns/div, the hack allows for 2ns. Not sure if there is a software 70MHz filter, I don't have a reliable way to test both configurations. I just like hacking shit
@@TheRetroChannel Thanks! I suppose the hack is more than the bandwidth limit, so I guess I'm kinda splitting hairs after thinking about it a bit more. Thanks for your reply. Really appreciate it. :)
6:07 ...can you retrofit it? Like, has the PCB provisions for the connectors and whatnot?
I believe the probes supplied with the DHO804 only rated for 150 MHz? That's why I've only done the option mod for 100 MHz. I was intrigued by the vendor.bin hack though. It would be nice to see a test on a 200 MHz signal.
True. I think people have done some tests with the original probes in the eevblog forum. I don't remember the results and finding them in that thread could be a challenge
Is it possible to add the logic analyser hardware to the DHO804 so you can actually use the logic analyser function when hacking the SW to the DHO924?
I know some people were looking into it on the eevblog forums, not sure if anyone managed to successfully do it
So, is that a persistant hack? Will the scope still believe it's a 900 series model after the next update?
El último paso me pone comando no válido y me quedo ahí he probado el resto de opciones y me dice lo mismo, sabrías que puede ser?

50Mpts memory depth do not work for me :(
Did you change the model to a 924 or use the unlock all options?
😂
when i push vendor.bin it asking that it needs a argument what should i do?
Double check you typed it in correctly. Technically 'push' is the argument
Sir can you help me to hack my scope personally
I will pay your fee whatever it will be.
Can you help me in hacking, because whatever i did but not able to hack it.i could pay your fee.
