Hacking the Rigol MSO5000 series oscilloscopes

[thm_w]

I installed this and it seems to have worked perfectly, with one exception. I cannot get the probe to compensate correctly on channel 1. On the other 3 channels I can get the probe compensated, but Channel 1 has a hump above the peak of the square wave regardless of the probe I use. Is this something wrong with the scope, or something wrong with the hack? Should I roll back to the non-hacked version? I'm not entirely sure how to resolve this.

Thanks,
Steven

It should be fixed in the next firmware version: https://www.eevblog.com/forum/blog/new-rigol-scope/msg2366808/#msg2366808

Thanks so much! Guess I missed that part reading through the long thread. Thanks so much for this work, guys and/or gals!

Can confirm, there's new cal routines in the coming firmware. Myself and a few others have been in contact with Rigol and ran the beta firmware. Goofy over/undershoot was fixed.

Currently working that same problem out on 7k series. New FW fixed a couple, but not all our 7ks.....

Have heard that there is a revised hardware for the MSO5000 to fix the screen brightness.
Just resistor changes apparently. New devices being shipped with this change - make sure you check before buying today.

[TK]

If Rigol is changing only some resistors, there might not be a way to identify the new scopes from the old ones... just purchase and pray?  Will they allow users change the resistors and honor the factory warranty, like what Siglent did with the missing capacitor in the SDS1202X-E front end?

Apparently not. Scopes at distributors need to go back to Germany to be fixed - so I'm told.

Any word on how they intend to handle existing units with what appears to be a manufacturing/design fault?

Damn 
Just last week I got my MSO5074 from Batronix. The Hardware version reported is 1.01.000. I suppose you guys have the same (meaning my unit hasn't been fixed yet)?

Do we have any idea of what serial number this LCD fix starts with? I am considering picking one of these up as an extra scope for the lab but prefer to have an updated unit from the start rather than having to mail it back.

[Magnum]

Batronix told me today that the display fix was already introduced a couple of months ago. Don't know if that is true.

[Martin72]

Couldn´t believe it, in several ways.

I´ve asked them(if the resistor-fix is true and how to handle it), answer should be given next week.

I got one MSO5074.
I though I can dump many times with high bandwidth for data aquctation.
but it's not possible.

Hope someone analysis this system. and make me code some custom programming with it's own component.
I looked some program binary but too huge lol

What were you expecting? What did you get?

400Mb of memory is a lot of data to transmit, even at perfect one gigabit Ethernet speeds it will take 4 seconds. In real life it's going to take a lot longer than that.

Dumping the memory in real time is a completely unrealistic expectation.

[pmnxis]

yes i know that's unrealistic issue with this stuff.
But I hoped continuous data logging with a short time (a second with high-time-divid resolution).

[pmnxis]

I guess how control external memory area(not directed connected 512MB, 1.25GB area and FPGA near the ADC frontend) and grabbing them.

implementing custom "dirty" "short-term" DAQ system.

guess Rigol MSO5k is developed for graph showing machine and s/w application is specific to graph purpose.

But I think it's possible for customizing to simple DAQ.

I am not good at reverse engineering. though I am trying to see appentry and zynq datasheet for is that possible and what can I do.

[nukecat]

Got the 5072 about a month ago. Thanks to everyone for making the hack possible, I'm very grateful!

[Martin72]

After all the confirmations that the hack work, today I can confirm that the way back is also no problem….

[Commodore8888]

^True.

You can flash pretty much whatever through the recovery menu on boot.

Patiently waiting to hear about the "resistor change" with regards to screen brightness though.
You sent yours in for service, right Martin? Did Rigol EU ever give you an answer about it? I'm going to probe the USA div and see what they say.
Worst case Rigol USA says "tough" and I pop mine open and swap it

[Martin72]

They told me to send it in the mid of june, next week, for fixing the noisy fan - And as I asked them what about the dim display, will it be fixed too, they said "probably"...
Maybe a service report will be attached when they send it back, that would be great to know what they did exactly.

[texaspyro]

If you send it in, it might come back with some new firmware that is not hackable... 

[Martin72]

I´ll take the risk and let you know what will happen.

[Fungus]

Yeah, the whole dim screen/recall thing is just a trap for to catch evil oscilloscope hackers.

[Martin72]

 

I´m pretty sure nothing will happen...
Much more important, what will they do...
Ah, in this case I probably find another bug:
Power On State....Choosable are last and default.
But whatever you choose, it´s always "last".

[maginnovision]

Maybe last is default, they just know they'd be ridiculed if they didn't give you an option.

Dear All,
a little help to a novice: I flashed 01.01.04.04 on my MSO5074 and while I can ping the scope, ssh gives me "connection refused"... anyone has experienced this?
