Rigol's New DHO800 Oscilloscope unbox & teardown

[ebastler]

We just use a wireless Logitek Keyboard and Mouse, both work on our Siglent. Just plug in the wireless USB dongle (we use a USB expander) and the scope recognizes both and it just works. Altho we don't generally need/use the keyboard, the mouse is always handy.

External keyboards won't work with the DHO 800/900 (so far), but the mouse should -- without an extra driver as you said, whether wireless or via cable. So "any old mouse" should do, with the exception of Bluetooth-based models.

I have just tried a wireless mouse via USB dongle on my DHO812 and can confirm that it works.

More correctly: They work, but they don't do much. The UI isn't designed for keyboard input.

I'd want WiFi and a mouse and probably USB stick. I guess that means a hub...

(Is there such a thing as a wireless USB hub?? )

Has anybody managed to install an FTP program on one of these? FTP access to screenshots is incredibly useful on my Micsig.

Maybe there's a neat way to capture screens on the PC via the web interface without having to copy/paste/crop/save each one individually. Or maybe use SCPI. It's not as good as just pressing a screenshot button on the 'scope though.

I wish some scope one day implements a function to save screenshots/capture logs to a remote NAS folder directly, like most office-class MFU do for scanned documents - for example Canon MF644 that I recently bought. It can also save directly to a PC, but it requires some client software running on it, while NAS is supported natively. Incredibly useful feature!

I'll try that one on the job someday: "Of course I worked all day, boss! I just didn't do much." 

Agree, technically the keyboard is recognized by the OS. But if you can't even enter number via the keyboard, in a situation where the scope lets you input them via a virtual touch keyboard, I would still say that the keyboard does not work (in the scope application).

Thanks! How do you like the on-screen touch UI and the screen in general? Is it largen enough to be useful for your taste?

One thing is sure: When something has this many options and settings available then anything else is going to be much worse.

eg. Could you imagine using your PC or phone using just six buttons and a rotary encoder?

I'll be getting a stylus and/or mouse with mine. A stylus is much more precise than a finger.

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

I do remember using my phone via just a rotary encoder. 

No doubt having the touch screen is a nice extra; and if I should find it too fiddly, I can always use a stylus, a mouse, or the knobs and buttons for all routine settings.

But the touch controls take room on the screen, and on the DHO 800/900 with its already small and 16:9 screen, they leave a relatively narrow "letterbox" area for the trace display. So one does pay a price for the touch funtionality in terms of screen real estate. Hence my questions around usability.

Yes, but you get a small device in exchange.

If you feel it's a problem then go for the DHO1000.

[Martin72]

Hmm...
Touchscreen has indeed it´s limits the smaller it goes.
I already had problems with the DHO4204 to hit the right spot, this will not get better with a smaller screen.

IMHO needing a mouse to drive a touchscreen based device means the UI hasn't been designed properly to begin with. Your comparison with a smartphone is on point; if they can do it for a smartphone, it should be doable for an oscilloscope. The key is to hide controls which aren't strictly needed. Like MicSig does for example.

It looks usable in the videos I've seen, but I'm sure there's somebody who'll complain.

I'm very used to using a stylus with my touchscreen laptop so it seems like the way to go.

Maybe it won't be - I don't use one with my Micsig but that doesn't have draggable windows or little close buttons.

We'll see when it arrives ... but I'm definitely going to try all three options (finger/mouse/stylus).

Agreed however a mouse speeds usage and when scroll wheel capability is available adjusting numeric values for some settings is much more convenient and faster.
Then of course you can instead enter a new value with a virtual keyboard.

[akkk44]

I output a NTSC bi-level sync signal from a sync generator but my DHO804 can not trigger with any video trigger type while my siglent 1102x-c can. Can someone here please confirm?

you can make PC client software to automate what you need through VISA driver..

they dont, partly. i just tried my wireless mouse+keyboard Gigabyte K7590... mouse does work, but when i tried to enter filename to save in local disk, dialog box that has on screen keyboard doesnt respond to my wireless keyboard, but the scope does respond to any keys when it asks "Press any key to exit" when i preview saved screenshot.

Hi! All!

I have a question - can I use 2nd channel on DHO804 as EXT trigger? - I need to align VHS VCR tape path, and still waiting delivery of my 804...

Thanks!

[Cees]

Yes you can select all channels for external trigger

[kirill_maker]

Thanks, will try after it will arrive

And have someone tried that battery pack?

[Cees]

I have the 924S so yes I tried it

[JOSM]

For my taste the screen is quite small. And some of the functionality can be reached via touch menus only. I found my Owon XDS2102A easier to operate. Maybe I just need to get used to the touchscreen operation yet?
The smaller footprint of the rigol is a plus though.

[wasedadoc]

Hi! All!

I have a question - can I use 2nd channel on DHO804 as EXT trigger?

That is not the accepted meaning of "EXT trigger".  But yes you can select it or any of the other three input channels as the trigger source.

[ebastler]

Umm -- tried what exactly? The piggyback battery pack mentioned in the post before yours? That would have been quick!
