Hacking the HDO1k/HDO4k Rigol 12 bit scope

[Domitronic]

There are no HDO1000 to be bought at all anywhere.. Production ramp up problems?

They might suffer the same supply chain issues as many other companies. And if the components are mostly the same for 2 products I would use them for the one with higher profit margin. So HDO4k might be preferred over HDO1k.

[thm_w]

where would they keep the ADC calibration data, if there's any? some eeprom or flash storage?

Flash or FRAM that tv84 posted above.

Correct me but the only 1000 we´ve seen was the one that Dave got.

i received my HDO1074 from Valuetronics in the US

Perfect!
Please let us know if the "upgrade" method from this thread is working.

I'm looking for HDO1000  UART decoder "review", in particular working with zoomed capture, it would be great if you could publish some screens and share your opinion about this functionality in main thread.

I spent about 1 hour trying to make it decode anything and was not able to make it work... even had some hangs and reboots.  I have the MSO5074 and using the same decode parameters it decodes correctly, but HDO1074 returns garbage.  Will test more during the weekend.  One annoying bug I found: If you change the timebase and starts scrolling, it disables decoding

EDIT: I made it decode by setting the threshold to above 3V (for a 5V UART signal).

[oliv3r]

Gee whizz, I certainly missed a lot I'll update the starting post with some key things written here

I already requested the GPL source code for both these scopes.

No response at all yet

They never responded to our MSO5000 requests years ago, they dont care.

Sure they did, I've had it for years now, and published the important bits https://gitlab.com/riglol/rigolee/u-boot and https://gitlab.com/riglol/rigolee/linux with tons of interesting branches I started a thread even about this https://www.eevblog.com/forum/testgear/zynq-700-based-rigol-software-development-(mso5k-ds7k-mso8k-and-probably-more)/ :p

Hi TK!
could you please tell us if decode/list window can be resized/moved from unusable layout shown in manual (side by side windows and weird list box) ?

Thanks!

Once again, Rigol seems to have released a device whose best purpose is to measure its noise floor...

Well, it's not unreasonable to have an analog signal focused scope, it doesn't even have an MSO option. And it seems the new R&S MXO4 has not done much better on initial tests. But now I am in limbo, have to wait for updated versions.

[voltsandjolts]

Hmm, buggy behaviour of the HDO1k doesn't bode well for the HDO4k...more expensive, more half-finished features, more bugs? Time will tell.

Not having MSO is bad enough, but not to have functional decoders while claiming they are there is just lame.

The R&S is actually a poster boy of bad practice lately in "Big Brand" crowd. They released RTB2000/RTM3000/RTA4000 equally non finished. It seems they try to lead by bad example here.

Damn, this is a huge show stopper ... 

It seems that this scope line does make use of complete different software platform compared to MSO5000.

Thank you for the test, i'll wait your WE testing update.

Tested a bit more, it looks like you can only have a side by side or top / bottom layout.  Event table is kind of mandatory as the way protocol decoding info is displayed in the waveform is kind of hard to read the values of the frames.  If I want to take advantage of the full sample memory, stop and zoom to decode, I cannot do it... as soon as I change the timebase, it says TOO MANY EVENTS or something like that and it does not decode. If I set it to a timebase where it still decodes, the update rate is like 1Hz... for a 115,200 baud rate UART decoding!!!  No wonder why it hangs with a 45MHz SPI signal... and it does not even decode correctly the frames.  I really cannot understand Rigol, they did not do the basic testing before releasing the scope, like someone sitting with the scope and testing it??

I've been busy with work so had only like 1-2 hour total to play with the scope, but will try make more tests during the weekend.

EDIT (TOO MANY EVENTS): The message I get is "There are too many results".  You can stop and zoom and get the packets.  But it works only up to 20ms timebase.  If you want to set 50ms or higher, then it says Operation Disabled.  Still a lot of freeze/reboot issues.

My MXO4 serial decoding locked up on first use. They have fixed it though, it was a rather obscure bug where I was adjusting the baud rate too fast and having something else on.
Around 6:40 is the problem

I'll have to play with the serial decoding and try and replicate. Couple of other videos to finish first though.

FWIW, I've been playing around with an R&S MXO4 for the past two days and have had the acquisition system stop acquiring samples under certain circumstances - much like what you were seeing in your video. All channels seem dead/frozen. This has happened 6 times so far and the only solution is a power-cycle. It seems to happen when you change the samples/sec setting rapidly (either directly through the acquisition menu using the knob, or indirectly via other actions like changing the sweep rate back and forth). I also had the UI crash once. I'm not sure what caused that, but it happened about a second after I turned on the spectrum window. In this case, the entire screen was frozen (including the clock in the corner) and all buttons - including power - were non-functional.

...And I've noticed at least another half-dozen minor UI bugs, like for example - where the measurement statistics table is not properly exposed when you turn it on and the only way to get it show is to toggle it off/on in the measurement menu.

Clearly the firmware isn't quite ready for prime-time.

On the other hand, even with the bugs, it's an amazing scope. The spectrum display, in particular, is probably the best I've seen on any scope regardless of price. Incredibly fast and behaves like a high end spectrum analyzer. It's such a huge contrast to the toy "math" FFTs found on most other scopes.

A bit off-topic for this thread - sorry.

Do you have a screenshot?

I agree. There is a separate topic dedicated to that new R&S.
And also a very unusually targeted 1st post..

There is? Are you referring to the "First picture on EEVblog ..." thread? That one seems dead. In any case, I was replying to Dave. Sorry for the OT post.

Don't worry. Hope you don't get offended either.
No matter if there were no posts for few weeks.  There would have been if all the ones writing about it elsewhere posted there.. :-)
I for one would be interested in more details. You can also open a new topic and post a small review if you have time for it...
