Sniffing the Rigol's internal I2C bus

[mauroh]

A big THANK YOU!! to all the guys that put all this effort to enhance our toys...
My new DS1074Z just became a wonderful DS1104Z with all Official options 

[Gallymimus]

Great work by the team working on this thread . . !!

It is time to upgrade my DS1102, and this thread is encouraging.

I may convince my pocket for DS4014 over DS2072A if it is really a good investment. I know the price of DS4014 is more than double + in import-duty bracket.

Could you please let me know if the DS4014 is upgradable successfully to 500MHz with options, if you have done an upgrade on DS4K.

Yes, DS4014 DS4000 series upgrades to 500MHz and options turned on using the keygens works great according to many people.

 Why don't you read the thread or search it so we don't clutter things up answering the same questions too many times.  I know it's a lot to read, but it's a small investment to cheat Rigol and save so much money.

Hi everybody,

Thanks for a great job with these scopes!
I have just successfully turned my new DS1074-S into a 1104-S with all options enabled.
The firmware version is 00.02.01SP1. The signal generator is as expected still fully functional.

I'd like to add one thing about entering the Riglol code: The upgrade is not possible during the first 40hours of trial period.
You get a "Invalid Code" message during that time.

I have also found an interesting link about DIY probes  that might interest those of you with faster scopes:

Rise time is abt 700 ps which would yield a bandwidth of 0.4/700x10^-12 = 570 MHz (which sounds a bit optimistic), but certainly way better than the original 70 MHz…

“a bit optimistic” is of course an understatement. But I am a bit at a loss as to how to interpret the rise time I measure with the pulse generator. It _looks_ like it meausere the whole pulse, so…
As a check I also tested my 5 year old OWON PDS7102T – a 100 MHz scope. Risetime measured was a bit above 3 ns (A bit difficult to measure, but not far off), resulting in 133 MHz.  Sounds reasonable. (see attachment). So this measurement seems to yield a more trustworthy result.
But: The OWON only rises to 12 Volts, whereas the upgrades 2072A rises to almost 40 Volts (both measurements with the pulse generator directly to the BNC, 1 meg input).
As a check I used the TG output of my 815-TG at various frequencies (0dBm output) and measured the Vrms reported by the scope. See 2nd attachment.
Note: the output of the 815 TG is not very well defined as we know, which explains the bumps and irregularities, but this measurement shows a bandwidth of just below 400 MHz. Sounds legit.
(nb: boy Am I glad I decided to buy the 2072 and not a new OWON.... )

I just spent about 45 minutes going through this thread to try to find it but cant... I am considering getting the DS1074Z, and I am curious where is the info to actually hack it in this thread?    Also where is the best place to buy it over here in the US?

Anyone who wants to change their new DS1074Z into a DS1104Z use the following Codes:-

DSHA  makes a  DS1104Z with no options enabled .
DSHR  makes a  DS1104Z with all options enabled .

The 3dB bandwidth for the DS1104Z is approx 160Mhz.
The 3dB bandwidth for the DS1074Z is approx 90Mhz.

Minor correction to my previous post after some further investigation.

DSHA also enables the 500uV setting and another unknown, (at present), option.

DSEA is the correct code to change to a DS1104Z only. ( no options ). See table below.

 Code      DS1104z    Unknown     500uV setting
DSBA                                               X
DSCA                            X
DSDA                            X                 X
DSEA           X
DSFA           X                                  X
DSGA           X               X
DSHA           X               X                 X

So to change a DS1074Z into a DS1104Z with all options enabled except the 500uV/div (which does not work correctly at present),
the code  will be DSER.

It is possible to revert back to original, by using the SCPI command " :SYSTem:OPTion:UNINSTall " .

As mentioned in my previous post, the measured 3dB down bandwidth after changing to a DS1104Z, is approx 160Mhz.
All the tests were done on a DS1074Z with Ver:00.02.00.SP1.

Is this entered in on the screen or done some other way?

[jrgandara]

tried to test this keys and I don´t see how to insert "-" between the codes generated in the Rigol keypad. Anyone can shed some ligth?
Thank you!

[madcrow]

AFAIK, you have to enter the keys without the dashes.

[swperk]

I've been trying to generate the "300 MHz, all options" license key for my DS2072A with the command "rigup license keyfile.txt NS8H" but the license that is returned is not valid. I substituted "0x1C0C7" for "NS8H" and got the identical invalid license. However, I have used the same command with the NSEQ argument to generate a license for "200 MHz, all options" and that key works as it should. Can anyone help me to figure out the problem?

Thanks,
Stan

[neslekkim]

I would use an hex editor and create the binary file instead, it didn't work for me to create the license from the textfile (What did you fill into the pub and privkey?)

Jahonen, the owner of that website is actually a member of this forum.
He created a topic about this probe here, where you can discuss it: https://www.eevblog.com/forum/projects/cheap-wideband-121-oscilloscope-probe-for-logic-signal-applications/

[johnny_canuck]

I installed options AAAC, AAAD, AAAE and AAAF on my DSA815TG last year using keys generated with KeyGen V2.0b1. They all work fine.
The DOS version of Riglol returns the same keys as KeyGen.
However, the only web version of riglol.3owl.com that returns the correct keys is from the Canadian mirror site at http://www.gotroot.ca/rigol/riglol.

Any explanation other than you gotta be a Canuck :-)

Also, option AAAB is the factory installed tracking generator. How about AAAA?

[johnny_canuck]

I just answered (one of) my own questions. In riglol.3owl.com, make sure that the serial number field is completely cleared before entering your serial number. Works fine on all sites including http://www.gotroot.ca/rigol/riglol .

Ok I thought the first time I asked where else to buy this scope I was losing my mind and thought I dreamed it when I woke up and saw my post was missing, now I know I am not when I see it disappeared a second time, wtf gives with that?!? I don't like being sensored when I ask where to buy something...

[neslekkim]

funny, I noticed that there are other post disapearing also, database issues?

One post disappears sure, 2 of them with 9 hour spread?

[Rigby]

Dave doesn't delete posts unless the poster requests the deletion, or you're attacking him personally in a post.

Database issues don't usually manifest themselves as posts that are there then gone.  Are you sure you actually posted?  If someone posts after you start writing yours, clicking "Post" will only show you a warning message stating that someone posted while you were writing, and not actually post the message.

I don't think asking where to buy the scope is much of an attack, I can't even see it meriting out of topicness considering the 198 pages of not that useful of posts in this thread... I am stumped and a bit upset over it, I just hope it's not commercial sensoring (trying to prevent mention of other vendors besides sponsors), that would sadden me heavily.
