Sniffing the Rigol's internal I2C bus
<< < (877/899) > >>

I'm really considering getting a Rigol since I have to diagnose some RFI issues in some projects and it will come handy for lots of stuff down the line. I have IDA 6.X with the decompilers (did not pay for the last upgrade haha!) and can do reversing if needed.

What is the status of the hack right now? Is there a bandwidth upgrade from 70 to 100 or 100 to 200 as it used to be? How about options?
If I end up getting a Rigol I will likely buy off Baronix since I'm in Europe... so I'm limited to whatever they are shipping right now.

Luckily it seems you can downgrade FW since they don't use any sort of e-fuses...

Cheers!
H.O:
"A Rigol" is pretty vague since they have at least 4 different series of scopes and DSO/MSO models in each series (except possibly the DS6000 series). If I'm not mistaken the unlock process is a bit different on different models. For some you might need to dump the firwmware while on other all you need to do is generate an option key and install it.

I'm not up to speed on it all but if you specify which model you're considering someone might give you a better answer.

With that said, their Ultra Vision platform is >5 years old now and depending on your needs there might be other suitable options.

hi,
I really wanna know, whether the new Rigol DS2000E/4000E series can be hacked. especially the DS4014E is a very affordable choice, only if can be hacked to 500MHz BW.

Thanks a lot for responding. I should have been more specific:

- I would like at least 200MHz achievable bandwidth either thru hacks or off the shelf. If I can score a DSO going higher than that through hacks, that would be great.
- Use will be debugging, looking at unknown signals from MCUs, diagnosing issues with resonators and some RF work, mostly repairs and such.
- I would love to have the ability to get FFTs and other math transformations. If it has a built-in decoder for signals... that would even be better!

I was looking at this Siglent unit:

But Rigol seems a lot more geared towards hobbyists, so I will definitely appreciate your suggestions.  Either way I have reverse engineering experience and got the necessary tools at hand including a (legitimate) pro licensed IDA with decompilers :)
H.O:
FFT is not something I personally use but from what I understand Rigol isn't doing very well in that department (you can Always export the data and perform the FFT on the PC if needed).

Since you're considering the Siglent SDS1202X I'm guessing 2 channels is "all you need"? If that's the case and 200MHz is "enough" then there's a lot to choose from but I'd personally put 4 channels way above good FFT functionality and I would not spend money on a built in function gen, I think it's better to have a separate unit. But that's me.

Take a look at the Siglent SDS1202X-E, and if you need four channels wait for the four channel version in that series (I hear Dave has one for teardown/Review so it'll probably show up sooner than later).

I don't know about hacks on anything except Rigol and I don't know if the new DS2000E and DS4000E series are hackable and if so to what extent. All I can really say from personal experience is that the DS4000 series ARE (closed case) hackable to enable full bandwidth (500MHz) and all the options (which you now get for free now anyway).

There are SO many considerations to make (which is shown again and again and again in all the "which scope is right for me threads") but, as was said in another thread if you want 4 channels and lot bandwidth then a DS4014 probably STILL is a good option despite it being 5-6 years old now.

For a general purpose scope, today, I'd want the R&S RTB2000 and I probably would've gotten one if the bastards would have offered the introductor deal in Europe and not only in the US.

And at the lower end the upcoming 4 channel Siglent is going to be interesting, since you mention 200MHz that might just be the unit for you.

But comparing a $400-500 Siglent SDS1202X-E to a $2000 Rigol DS4000 or a $3000 RTB2004 (200MHz) isn't really "fair" from any perspective.
