Sniffing the Rigol's internal I2C bus

[jamesb]

Excellent work and seriously tempting me to buy a DSA815 (and DS2000 if that gets hacked...)

... you are kidding, right?

[olsenn]

Now I'll uninstall the keys since the tested software appears to have worked ... 

Right....... I'm sure you will...

[true]

Doesn't matter who he is. His response surely didn't match his work. You expect everyone to know exactly what to do with that script?

If you don't know what to do with that "script", where the instructions are in the file itself, well, maybe you can ask your attitude.

so I'm hoping the comment above doesn't discourage someone from developing a Windows GUI.

lol who takes such a thing serious, I'm sure nobody cares

Wow I go offline for a weekend and more awesomeness!

Don't have the DSA but binaries up at http://gotroot.ca/rigol as usual .

Nice work with the 10Hz RBW  . Does anyone know if the 3Ghz BW is also software specific? That would be a nice option to go along with the 10Hz RBW.

question tool all:

is ther any one with a dsa815 (NON-TG) willing to do a open it out there??

we Need some Fotos of the PCB to see if it is only the N-connector that is missing or what elce is missing.

thanks to all

Yes. Ha ha. You got me.

Does the 815 non-TG have the TG N-connector in place?? Oddly the only picture I've seen has been with 2 N-connectors at the front. If so it certainly looks promising for a "software-upgrade".

For those who has dismembered the 815... how about measure the IF filter size, this way we could estimate the IF frequency, and thus see if the 815 is hardware designed for a higher than 1,5 GHz stop frequency. Or even better try to measure the cut-off frequency of the first low-pass filter. But this may be a though job.

[tom66]

I think the tracking generator is a substantial cost on the unit (if you look at the teardown.) I doubt they are including that with every unit. 3GHz vs. 1.5GHz may also require some changes to the PCB filters?

Looks like you are serious...

Did you read any of the earlier pages in this thread?

Oh wait, of course you didn't! Otherwise you would realise that what you are asking has already been done.

[tom66]

I didn't read through the thread, not all 60 pages. I didn't realise it had already been hacked. If so, great! Now I have double the reason to get the DS2000.

[olsenn]

For the DS2000 I recall it was possible to change a DS2072 into thinking it is a DS2022 to get greater bandwidth. I wonder what happens if that same procedure is done to change the DSA815 into thinking it is a DSA830?

[tom66]

Is there a dedicated thread on DS2000 hacking, or is it all in this thread?

it's all in one

You are looking at it.

To be honest, I like the fact that the procedure is a bit convoluted and requires some background research - it should help keep the effort / success a bit more low-key and reward those who are more dedicated than the average script-kiddie type.

Someone is bound to write up a full "how-to" on a blog site somewhere - hell, I was considering an in-depth tutorial until I considered the ramifications.

[tom66]

Great. There are already how-tos on the net. And a Windows EXE for the DS2000. I can quite easily compile a linux gcc, if I can find the libraries. First, I need to sell my DS1102E (not hacked, all original) if the DS2072 is to be my next purchase. I am really missing the intensity grading that I get on the uni lab scopes (Agilent DSO4000 IIRC)

Hi,

It seems that there are lots of parts for the TG option input. See attached images of back side of board. The DC block cap at RF input may also limit the analyser range to around 2G.

[jamesb]

Wow ... some really scary / poorly done reflow on that board. Good thing it works .. but .. wow ...

On the following page is a picture of a DSA815 without TG and with only one N-connector:

For those trying to build miracl.a on a 64 bit Linux platform (Ubuntu 13.04 in my case), the instructions at the top of rikey_dsa.c (and rikey_true.c) need to be tweaked a bit. I used 'bash linux64' to build miracl.a then '-m64' rather than '-m32' on the link line.

Nice catch for the 64bit crowd!

[Mr Simpleton]

Maybe not the correct thread to ask... but looking at the phase noise data on the DSA815 it is not that spectacular at close in, is the 10 Hz RBW really that useful? It seems several forum members mentions that the 10 Hz filter does make a difference when trying to resolve signals. I would love to se a plot showing the improvement. Any taker?? 

[cybernet]

i'd recommend -m32 even on a 64bit system - i had several inconsistent builds on 64 bit boxes, maybe invalid type casts on my end or miracl issues. 32bit fallback solved it every time.

[cybernet]

pm me the output (+serial), i can verify it the other way around - so far all error reports where due to typos 

[Rory]

Thanks Cybernet and dr.diesel, I'm up and running on all.

The license info still shows the trial options by their keys and their "left time". I assume the trials will disappear once they expire?
