Sniffing the Rigol's internal I2C bus

[Dave Turner]

I have searched this forum for 00.02.00.SP1 which is the software version on my DS1074Z-S to no avail. Has anyone looked at this firmware?

[evanh]

What do you mean your private key is longer? Or are you actually talking about your serial number? That's not the same as the private key.
The private key is the same for every DS1000Z.

You can find the 4 different private keys for DP832, DS2000, DSA815 and DS1000Z respectively in riglol.c available in riglol.zip at the bottom of this website http://riglol.3owl.com

Ah, thanks for the info.  I now realise I'd assumed the product key was the same thing.  I'd just received a product key from Rigol for enabling a feature on my scope.

I also noticed last night riglol is not quite the same as rigolkey ...

I think studio25's RigLOL is the only version still maintained. It's also easy to use as you don't need to compile or install anything. As it runs in a web-browser it works on any platform, so you don't have to maintain different versions for Linux, Windows, OS X, Android or whatever.

The keys generated by  RiGen.exe   and    riglol.exe,    have both worked successfully in my new DS1074Z to permanently enable all of the options.

Have not seen that the ds1074z gets 100MHz BW increase with the hack... Is that a TBD at this point, an unknown, or a HW difference?  Weighing options between 1000z-s and 2000a-s.

[evanh]

Riglol worked for me.  My scope now has one official key plus one cracked key.

Interestingly, they are totally different code sequences which doesn't seem surprising, I guess, except that all the cracked keys have the same character sequence for the first half of the key code.

I'm gonna guess it's to be discovered.  The diff between 70 and 100 is too small to have different hardware for each, especially given Rigol's history in this area.

Four channels makes a huge diff over two when comparing timings.  My uses cover from signal integrity to both analogue and digital data logging with the occasional bit of high speed logic.  I use it as the jack of all trades.  I've had four channels since 2002, I could never go back.  I was drooling over an eight channel DSO back then but that was way, way, way out of my price bracket.

I purchased the DS1074Z-S, because it's a tenth of the price of what I already have, and to see if it lives up to it's specs and hopefully be able to recommend it.  And I do highly recommend it.

I suspect there will eventually be a four channel DS2000.  But how long can you wait?


I've continued my ramblings about the DS1000Z back in the quick look topic - https://www.eevblog.com/forum/blog/eevblog-522-rigol-ds1000z-oscilloscope-quick-look/msg326311/#msg326311

FWIW, seems that site/page is QRT. ("Off the air.")

But I don't see a DS2072A version listed on Rigol's web site, just the DS2072.

Maybe you are looking at Rigol North America's website http://www.rigolna.com or Rigol Europe's website: http://www.eu.rigolna.com

DS2000A is not listed there yet so, switch to the international Rigol website in the top right corner. http://www.rigol.com and you will see both a DS2000 series + a Series DS2000A listed.
DS2000: http://www.rigol.com/prodserv/DS2000
DS2000A: http://www.rigol.com/prodserv/DS2000A

DS2000: http://www.rigol.com/prodserv/DS2000 This link still works but it can not be accessed from the international home page. It seems all links to DS2000 series have been replaced with DS2000A series. This was not case when I looked 2 days ago.

Both sites still works just fine for me if I use the direct links and shows two different websites, when I select "International" in the top right corner at http://www.rigol.com.

However the at the DS2000A there's an "Ordering Information" table near the bottom of the page.
This "Ordering Information" table has disappeared from the DS2000 site and the DS2000 link has also disappeared from the drop down menu at the top under Products -> Digial Oscilloscopes.
So you can probably only order the DS2000A model now, once DS2000 stock runs out at dealers.

Yes, just noticed this. Worked fine some hours ago when I made my post.
Any idea why the site has been taken down? Is it Rigol who has asked 3owl to remove it, or is it taken down by studio25, maybe for an update?
The site just says this now:

It says free unlimited bandwidth, so I guess it's not because of too much traffic that it's not available anymore.

The Dynasty strikes back...?   

[Co6aka]

For whatever it's worth... Today I stumbled over the following bit of info:

Supposedly, for the DSA1000-series, the service menu is accessed by pressing: Frequency, Span, Amplitude, Trigger, Bandwidth, Sweep, Single, Continue, Trigger, Trigger. (Whew! Like it's some kind of national secret in there!)

Wondering if it's the same or similar for the DSA8-series...?

[evanh]

Hehe, a bit more than your average PIN.  I guess the question also falls to all the Rigol equipment.

[Co6aka]

The obsession with "secrecy" smacks of the good ol' cold-war days...      Heck, I'd publish the access sequences and hope to make a mint re-aligning and re-calibrating all the instruments the diddle-dummies mangle!    Unless of course I was getting a nice kickback from the cal labs. (But then the cal labs wouldn't be telling fellow techies the access sequences...  I dunno...)

DDOS attack (IP Nullrouted)

I smell Chop Phooey! (From "#1 Chinese Kitchen") 

Anyway...

Been looking at other stuff from other places and, unless my doggie-nose has lost the scent trail, am wondering if license codes for the same feature in different versions DS4000-series scopes (DS4014 vs. DS4054 for example) are the same? Also, along the same line, why are the "critical letters" in license codes for different models different, if the option bits are just the lowest order bits? ("MWxx" for DP832, "DSA/Bx" for DS1&2-series, "DSHx" for DS4-series, "AAAx" for DSA8-series.)

Hello,
I'm new to the forum.
I wanted to buy a Rigol oscilloscope and I'm curious to know if the DSAZ option of the trick works or can work also on the new DS2072A-S with 2 Ch waveform generator

Someone has already done a test?

Thank you and congratulations for the work you have done.

[Reboot]

After watching Dave's and marmad's videos of the DS2000 series scopes, i'm pretty much blown away by what it can do.  I have used my trusty Tek TDS3034 scope for years and I like it very much, but it is looking downright crusty compared to Rigol's offering.  The "must have a new one" feature of the rigol is its waveform capture and deep memory, the Tek just doesn't cut it for capturing intermittent problems.

I ordered a DS2072 from Tequipment today, and can't wait to get it.  I wish they made it in 4 channel form, as that is quite useful to me.  I looked at the 4000 series, but it is quite a bit more for the same features really, and I like the front panel layout of the 2000 much better.

I think the lower bandwidth may be a limitation with some of the stuff I do, but I still will have my tek for that...

[Dave Turner]

On the DS1000Z series has anyone checked to see whether the 500uV range is actually useable after being activated?

Are you aware the bandwidth can be increased to 200 MHz among many other options with a simple license key entry? (Hint: read the entire thread here...)

I'm hoping that I can eventually get the CAN decoding on it as well since it doesn't seem to be a hardware change with the scope.  I have another solution for logging CAN traffic, but having it on the scope as well would be great for initial test of new board designs.

Thank you and congratulations for the work you have done.

I have read all the posts and threads about it, if I understand it, since the modification for the DS2072 seems to work also on the DS2072A, I think there is good chance that it works also on the DS2072A-S (I just hope that with the version of fw mounted, able to handle even the components for the generation of signals that is missing on other models, they do not have locked the trick).

I said well or you think I'm wrong?

I want an oscilloscope for small home projects, and I would also buy a simple function generator (if possible also  arbitrary), the DS2072A-S has them both.. But the thing that interests me most of all is the possibility to decode serial signals.

Your suggestion is not to take risks and take two separate, a DS2072 and a function generator or groped quietly with the DS2072A-S?

Thanks in advance and sorry for my bad English!

Wouldn't it be better to cancel the order then and wait for a DS2072A instead? Especially since you already have another scope to use while waiting.
DS2072A comes with CAN from the factory and there's also a 300 MHz version called DS2302A, so you might be able to upgrade to 300 MHz, like the BW of you TEK scope.
There's still no known way to add CAN decoding to the non A DS2000's.
