They'll be dual differential output (LVDS or ECL) comparators. Shouldn't be too hard to find
ADCMP567 a possibility? 2 channel, right number of pins.
ADCMP567 has 32 pins , x-ray shows 24
I Can't count, sorry.
Closer xray attached. I can get closer and tweak settings if it help.
As there's no processor or eeprom in there, the functionality is likely to me enabled by a pullup or pulldown on the connector - shouldn't be hard to find with some poking around with a 100R resistor to avoid smoke.
Power outs should be easy to find.
If you get the digital menus working, you can then tweak thresholds and see which pin(s) set this.

All the pinouts I can see are consistent with LMH7322
Functionality is enabled in the scope even without it plugged in, just hit the LA button and you get all the options available.
Looks like it's an easy enough design to knock together for cheap then, if anybody can be arsed.
I'll have another look at what's holding the case together, it's not responded to force so far.
Is it simple enough to DIY the logic analyzer header? A few hundred bucks from RIGOL otherwise!
The Christmas gift for all Rigol fans out here:

PS: And it's not an hack. It's a feature!
great, i have read this thread a bit, but oversaw your post, and ordered day later SDS1204X-E instead of Rigol (due to 4 vs 2 channels).
Anyway, will do it as eastern gift ^^
Anybody fancy guessing what these 8 (identical I assume) IC's might be? Or do I have to get all medieval on it, no screws or clips unfortunately...
Normally they're comparators with selectable references for all the different voltages in the menu:
I concur with mikelectricstuff about the
https://www.ti.com/lit/ds/symlink/lmh7322.pdf, good catch!... not entirely sure on the shorted latch pins though (LEA, (not LEA) and VCCOA) since not all QFN footprints have the 3 "shorted" legs on the same pins, perhaps some of the parts have different orientations on the board? Other intended functions or just routed differently on the PCB?
I also wonder if TopLoser could get some of the values of the passives by probing the pins of the probe and get some cap/resistance values out of it so that we can compare it with the typical applications on the aforementioned datasheet?

If the reference voltages com from the 'scope then that makes it a lot easier.

Started to see the 4 chan out of stock in Canada, I suspect the 2 channel will follow suit now.
Genius marketing move. I'm not even in the market for a scope and I'm considering one...
Anybody who thinks the hackers are getting something for free has it all ass-backwards.
The hackers are paying the regular price, it's all the businesses and educational institutions that are paying extra.

I"m not so sure. Let's wait until the real hacking begins.

I'm pretty sure sane businesses and educational institutes are going to wait until the hobbyists bought enough units so Rigol finishes the firmware. It also depends on whether Rigol blocks the extremely simple workaround (it isn't even a hack) to enable all features in a future firmware update.
I feel like removing the firmware hack would tank potential hobbyist sales? This might not be much, but again, in a world where hobbyists aren't buying the high end features, and institutions are, it's just icing on the cake to attract that market.

When I read the posts in the test equipment section I get the feeling there are quite a few hobbyists out there which spend several $k on a single piece test equipment. This market isn't big but it does seem to exist.
Simply removing the feature is not a show stopper. We now know it can be done.
What I would like to know is: how similar is the HW in the 5000 and 7000 models? Can someone please elaborate?
I guess Rigol and it's big distributors are watching the market, observing and going to conclude whether next move will be to lock or keep it open.
For sure they will at least get the free marketing and gathered accurately on the market reaction on this price level.

They've had ten years to make that decision before launching this one.
I'm guessing DS1054Z sales already showed the economics work just fine.
I am between two chairs…
Buying the option bundle which costs about 700€ incl. tax don´t worry me.
The memory upgrade.... I´m not interested in - 100M standard is more than enough.
But the bandwith upgrades..
The price killing me as an owner of a 5074.
Buying the options but hacking the bandwith, this is in my mind, weird…
Maybe an ‘extended trial’ would be an acceptable option for you
Bear in mind that Rigol will offer a ‘free option bundle’ for these scopes at some time in the future. That would make you pretty upset if you paid for the bundle already...

Don't understand your dilemma.
The fullopt provides max BW and options simultaneously. If you have extra cash, go for the 7000.
