Rigol's New DHO800 Oscilloscope unbox & teardown

[dreamcat4]

LOL it is a six years newer design.  What exactly would you expect?

for siglent to keep working on developing new scopes, new generations of product.

[.RC.]

I expect they or someone else will. The 1054Z is over eight years old alone.

 Maybe Fnirsi will come out with a 12bit scope.

or owon. but both finisri and owon are even cheaper brands than rigol

Just for an info... Owon already have both 12 and 14-bit oscilloscopes 5 ears ago, u can also check them on baltronix https://www.batronix.com/shop/oscilloscopes/Owon-XDS.html
U can even find Dave's review for Owon's 14 bit dated for 2017

You're teasing me... 

Here.

I think this really settles it now, the DHO804 is the new de-facto "beginner" or budget scope

Yep. It destroys that Siglent 1104X-E and it's $100 less.

It does not destroy it. It brings in affordable 12 bit that's all.
SDS1104X-E has many features that DHO800 does not have.

For instance, old DS1000Z has better layout of measurements than DHO800. How many measurements with stats can you have on screen at the same time on DHO800?

It depends what you do ..

[Mortymore]

The price depends where you get it from, but looking at Batronix for instance, as for today, the Siglent SDS1104X-E (€460) is cheaper than the Rigol DHO804 (€475)

With regards to the lack of time and date, plugging it into the ethernet set the time and date, but the time here in Sydney is displayed as two hours behind on the screen shot.
So this seems liek a very deliberate cost cutting measure.

Somebody posted the boot code earlier and it sets the time zone to Shanghai.

I don't know if there's a setting for that or if you have to edit the file.

There's the DHO900 if you want those extra things.

[Fungus]

For "only" 2500 bucks more you get a second ADC, a bigger screen and a different FPGA, thats all.

What about the auto-probe detection and power analysis functions?

[Fungus]

I have an idea. If I can dismantle the ADC and front-end chip from a DHO802 and transplant them to a DHO1072, then upgrade the firmware to DHO4804, would I be able to get an 800MHz/4Gsample oscilloscope for $1000?

Yes!

Big discount from Siglent.

(They're not going to sell any more of those if they don't do that...)

Yep, looks like the only option that Rigon doesn't provide for DHO900 is a WIFI module, but since you have a LAN onboard u can just use any generic Ethernet-2-WIFI adapter (iogear and tp-link produce not the worst ones), and you can get even more wireless option for the less money then Siglent provides.

Having owned the owo all I can say is this,  it an expensive door stop 

[Sighound36]

I have to say it's refreshing to see more Rigol mentioned of late on the TE board, such a refreshing change

Yes!

Did I miss somebody did this or what?

[blargg]

BTW the Discover It credit card's October-December 5% cashback category includes Amazon (and during the first year of the card you get cashback match, so 10% off). I'm waiting until Oct to place the pre-order for this scope on Amazon.

Siglent is making 10% discount until the end of the month, but at the regular price of €510 it's €35 more expensive than the Rigol (€475), not $100 more.

And I agree with you about Siglent keeping the current price if they want to sell one or two extra SDS1104X-E because no matter the price difference (not much below, even worst if above the Rigol price tag) I think the DHO804 is a "winner, winner chicken diner"  as "someone" says.

Better wait for some real hands-on experience from people who put the pedal to the metal. Showing waveforms is like 5% of what a modern day DSO should be able to do. On top of that, making actual use of 12 bit requires some new features as well like filtering and being able to zoom in so you can look at a signal at like 10uV/div. Knowing Rigol's history, there will be tons of bugs that takes years to fix. People get all exited about new equipment and then are super happy with every firmware release that fixes problems/bugs that should not have been there in the first place. Look at how many people have returned the Rigol MSO5000. So, yeah, I'm sceptical.

As I said, depends were you get it

Lets make it official then, but in Europe

https://www.siglent.eu/product/1139249/siglent-sds1104x-e-100mhz-four-channel-oscilloscope
https://rigolshop.eu/dho804.html

That's the same prices as Batronix.

This is why Dave says in the latest video he wouldn't discuss prices from other countries. I just brought an european perspective.

Well I thought that some of these things were demo'd fairly concisely in Dave's 1 hour full review today. Including things like the 12-bits resolution (zooming) and some certain specific bugs he noticed during the course of his review.

But in addition Dave also demo'd pretty well a couple of bugs or not working, and alluded to perhaps getting a 900 series in later on in the future. To do some additional reviewing of that model too. (which would be great, to also then see those extra stuff it comes with and the higher bandwidth probes etc).

And yes - in terms of people not getting on with the MSO5000 I myself considered that scope, and finally was a hard pass on it. But just because the MSO5000 was not up to my own standards doesn't mean that this DHO800 isn't acceptable, when also considering the significantly lower price point.

However as for the unfixed bugs I do agree completely and that does indeed still remain the biggest concern for me overall. Especially when looking at how long the other DHO1000/DHO4000 series have already been out for.

The better question is what can we do, to increase the chances of them fixing known firmware bugs? And what are Rigol's future plans for those firmware teams and the software platform, these hardware platforms overall?

The thing that I would expect is for them to next focus on producing a version of HDO1000 series with LA and AWG. If the current 1000 is like the 800, then it needs a mixed signal version to complete the lineup, and that would also finally replace / retire the slightly older MSO5000 series.

No. Not by a long shot. Testing a modern DSO thouroughly takes several days of work to go through an extensive list of tests including tests that are designed to seek out the limits. And even then there might be surprises lingering. Keep in mind that Rigol (and Siglent too; look at how they copy Lecroy's UI instead of making an innovative UI themselves) are relatively new to the DSO game and have not learned all the ins & outs to make the right design choices. At least Rigol seems to be trying to take a stab at creating an innovative UI. Probably inspired by R&S.

The possibilities to design an intuitive and logical user interface are rather limited, so you will almost inevitably always have similarities to other UIs.
