Rigol's New DHO800 Oscilloscope unbox & teardown

[ebastler]

report your bug here people.. https://www.eevblog.com/forum/testgear/rigol-dho800-12bit-dso-bug-list/ let this thread discuss technical...

No, please report them in the already existing dedicated bug-report thread: https://www.eevblog.com/forum/testgear/rigol-dho800900-oscilloscope-bug-reports-firmware/

It was about the ext trigger function

[Malmen]

Thanks, will try after it will arrive

And have someone tried that battery pack?

Funkar fint med vilket 12 volt som helst. Jag kör med ett 4S Lifepo4 pack som ger runt 13 volt. Köpte en USB-C kabel på Biltema och satte dit kontakter som passade mitt RC batteri. Skaffade även en batteriövervakare som larmar om någon cell börjar bli för låg.

Has anyone checked if the USB-C power connector has data too?  Can we power the scope through a powered hub with our USB devices connected to that hub?

Just got my 802 from AliExpress.  Great functionality.  I can’t get the cursors to show up on the FFT window.  Dave’s review had them on the FFT window along with the measurements.  The cursor button will add them to waveform view but doesn’t add to FFT window even when it’s full screen.  What am I doing wrong?

Rigol DHO800 Aliasing effect
It's not a bug, but could be fixed. Press "Default", use 12.5 MHz (or 25, 20, 10, 5 MHz), 1k memory depth, increase the timebase until aliasing appears. Firmware version 1.00.

This will only work for configurations where the aliasing is caused by the display engine of the scope, i.e. the sampling setup still meets the Shannon requirements. If the acquisition engine causes the aliasing, the "hardware" frequency counter won't help you since its signal is derived "digitally" from after the ADC as I have demonstrated here: https://www.eevblog.com/forum/testgear/rigol-dho804-test-and-compare-thread/msg5106558/#msg5106558

I had a quick play with one at the EDS  show today.
UI seemed very responsive.
Smaller than I was expecting, I think maybe a little too small for the amount of stuff on the screen - not good if you have trouble reading small text.
The same scope with a bigger screen would probably have a market.
Slightly disconcerting thing was that normally on a scope you expect to see a little "grass" of noise on a live trace which confirms it's running as opposed to waiting for trigger - the combination of the 12 bit ADC and small screen meant that it was sometimes impossible to see any difference between a live trace and a frozen one - there is a fairly clear trigger indication at the top-left of the screen which I'm sure you'd get used to.

You mean like the DHO1000? 

I'm wondering if the price of those will drop once the DHO800 supply situation settles down.

Maybe also a version of that with logic analyzer will also appear and replace the MSO5000.

On my trusty DS1054Z I love Peter Dreisiebner's "Bildschirmkopie". Triggering the capture right from the PC, then either copy/pasting it right into a document or saving it under a meaningful name (which I can enter using an actual keyboard!) is a great workflow for my taste. And it is really snappy, especially over the USB connection.

Peter, who is active as "PeDre" on this forum, mentioned a while ago that the program should also work with the MSO5000 series, since Rigol's SCPI commands are pretty consistent across their product lines. So it might work with the DHO series too? If it doesn't, maybe Peter is willing to consider requests. 

Bildschirmkopie has been stable for a few years now. It can still be downloaded from Peter's website: https://www.dreisiebner.at/temp/rigol-bildschirmkopie.zip

Quick follow-up on my own post: I just saw in another thread that "Bildschirmkopie" does not work with the DHO series so far. PeDre has replied with a possible fix, but that is yet to be confirmed: https://www.eevblog.com/forum/testgear/rigol-screen-capture-vcl-windows-application/msg5108583/#msg5108583

Mine's arrived at my city but today is a public holiday(*) so I guess I'm not getting it today.

(*) The second one this week - that's Spain for you.

Working fine here with the 924S

New firmware:

v00.01.01.00.01  2023/08/10

1. Remove all time-related displays on the instrument
2. To modify the vertical interface, click the wiring diagram to modify the AC coupling function
3. Modify the delayed scan Chinese display as Zoom
4. Modify the order of the menu in the upper right corner, put the measurement in the front and Default in the back
5. The probe ratio interface is removed, and the probe ratio option is added to the vertical first-level menu

Thanks, nice find!

I assume the "remove all time-related displays" refers to the time of day, which was rather meaningless without a battery-buffered clock. Otherwise, none of the issues mentioned in the bug-report thread here on the forum seems to be addressed yet. But good to see that Rigol does have someone working on the firmware; let's hope for a next release soon.

And we can see where they are still experimenting with GUI features and positioning...
Let's hope they will listen closely to user base and make note..

Has anyone tried the Bode Plot function yet after this update?

It's only been out for a few hours!

Yes, but young people these days are faster than I am.

There's a thread for that!   And didn't you already thank Cees, who stated there that it is fixed? https://www.eevblog.com/forum/testgear/rigol-dho914s-bode-plot/msg5109180/#msg5109180

Yes, I thanked him for the link to the update.
My update is now in process.

My new Bode plot after update:  https://www.eevblog.com/forum/testgear/rigol-dho914s-bode-plot/msg5109597/#msg5109597
I am still disappointed.
