Rigol's New DHO800 Oscilloscope unbox & teardown

[Aldo22]

A manufacturer launches a 16-bit, 4-channel, portable, ground isolated oscilloscope for pocket money (did I mention it's 16-bit?)

Do not exaggerate, 12-bit vertical resolution is enough.

Good point, well made!  I'll go and make the correction.

Mind you, give them a couple of years... :-)

For those who missed the unboxing (teaser) by Dave.

[Martin72]

Aha, so Dave also has a 1000 and a 4000 Rigol in the lab - Where are the full reviews ?

[BreakingOhmsLaw]

Wow, that thing is going to wipe the floor with anything else in the entry level market.
Fleabay is going to be absolutely flooded with 8-bit scopes.

[Martin72]

Wait and see.
Unpacking, turning it on and playing around with it does not say anything about the actual capabilities.
On paper, of course, the matter is clear, but only when it is proven should we bury the old kings and praise the new king.

Some people on YT make a living doing just that.

"Look on my Works, ye Mighty, and despair!"

Of course, he could equally well have been referring to Rigol's software release management process / clown show 

Nonetheless, there's a good chance, based on reviews of the 1000 and 4000 series that this thing will be a "go" but yes, still all to play for at this time, in my view.  Until we have some concrete, engineering-led reviews, it's still perfectly possible for Rigol to snatch failure from the jaws of success.

I shan't be placing an order until Dave et al have "turned it on" and possibly, "taken it apart".

He did turn it on and after only 54 seconds it was ready. 
It may sound ridiculous to some, but to me that's already quite a show-stopper.
The pathetic Hantek DSO2D10 is ready in 10 seconds.
Granted, you might have to reboot that more often than the Rigol, but do we know?

[StillTrying]

I can't find any option to increase the waveform viewing screen height in DHO800_UserGuide_EN.pdf.

So most of the time it's showing ~4096 Y levels in ~400 Y pixels.

No Dots mode.

Never really understood why boot time for scopes mattered. I have a RTO1024 as the main scope at work. 2-3+ minutes to boot up plus a recommended 1+ hour warm up time.

Not really apples to apples here but 99 times out of 100 you'd have your scope running and warmed up before doing anything.

For a multimeter however I'd understand.

It's cute, so thin. It's like phones now - they really can't be made smaller or you couldn't even hold them.

A nice little DSO! What I don't like:
- glare-type display (light reflections can make reading the display hard)
- touchscreen (a personal preference, fiddly in some environments)
- separate grounding/PE wire (asks for trouble)

[Fungus]

How's the fan noise?

That kinda comes with capacitive touch screens (ever see a matte smartphone?).

A screen filter will fix it, just like I have on my Micsig.

- touchscreen (a personal preference, fiddly in some environments)

You can also use a mouse, etc.

I already bought a USB-C right angle adapter for when I get my DHO800...

Add more touchscreen T&M gear and you'll need a USB switch to prevent the mess of half a dozen mice occupying your work bench.

You can hear it clearly in Daves unboxing video, but that was to be expected(small fan).

Where? Dave doesn't stop yakking for a single second.

(and I don't know if he has noise reduction on)

[Martin72]

Damn, I could swear yesterday I´ve heard it loud and clear...
Now I hear only Dave..

The pathetic Hantek DSO2D10 is ready in 10 seconds.

And it's not worth the wait.  I'd much rather wait a minute for my Siglent.

I just ordered a DHO804 from aliexpress 569CAD including import tax. Now I need to sell my almost like new DS1054z (hacked to 100Mhz).
Curious what I will get on the old DS1054z on eBay hopefully at least 300CAD.
I was looking for a low cost 12bit scope and this DHO800 series is exactly what I wanted. I have an application where I need to measure current as voltage drop on a current shunt and force on a load cell and 8bit (256 steps) was just not quite good enough even with amplification just to low of a resolution.

[BillyO]

Kudos!

Give us a report when it get's in.

You can hear it here:

Could be a little bit annoying.

That's with some crappy automatic gain control maxing out the volume level.

Disable button on the front panel. Everything can be done without the touch screen.
