Rigol DHO800/900 pre-sales begin

[zrq]

Maybe a DHO914 non S is a better deal if the signal generator is hackable (is it?).

[RAPo]

Got a lowest price guarantee from Batronix.
Will order a DHO924S.
And  I already have the LA-probe, so this going to be fun.

[Aldo22]

Why would they offer so many 2-channel oscilloscopes if nobody is interested in them?

  I guess you answered your own question.

How? Can you explain?

My question is not so difficult after all.
Martin72 said that no one was interested in the 2-channel version of the DHO800 and I asked why.
I understand that Martin72 is not interested in the 2-channel version, but why does he say that "nobody" is interested?
Is there a specific reason for this regarding the DHO800?
I believe that more 2Ch than 4Ch oscilloscopes are sold in general, so I would like to understand why Martin72 says this regarding the DHO800.

I really don't want to argue, I just don't understand.

DHO914 and DHO924 are without AWG output connector

[trp806mo]

I would more ask myself if I need a 2 or 4 inputs for my scope without bother me with what the others are using. But from my (little) experience I had never seen a 2 inputs scope in all the labs i've seen and for my personal use I have 2 scopes because i don't have even some time enough inputs (checking power supplies of the modern boards which have multiple power rails, checking buses, ...)

[simone.pignatti]

Hopefully we will have one unit to test in our office on September the 11th.
In the meanwhile I found this video, it's in Chinese but it easy to follow:

DHO800 because it is the most affordable scope series among rigol's new 12-bit models.
And of these, the DHO802 is the cheapest because it has only two channels.
The difference is only about 120€ between 2 and 4 channels, nevertheless there will be people who want to save and will buy the two-channel.
And I think that saved at the wrong end, because as I said, there will be a day when you realize that you now need more than 2 channels - and then you do not have them.
And if you then can not get around it, you have to take money in hand again and buy a 4-channel, because you had saved "then" 120 €.
And yes, this is really just my personal opinion, even if somewhat missionary presented.

I find the addition of both the 800 and 900 series models to be an 'interesting' decision.

It feels to me as if the mixed signal capability was wished for by the product manager for the DHO1000 and DHO4000 series but wasn't possible to deliver within the timescale slated for their release, hence it was pushed down in the backlog, to be implemented as a feature for the later 900 series.  Amongst other things, the cost of additional LA probes becomes less disproportionate set in the context of the price points of these models.  The 10" displays on the DHO1000/4000 also seem more suited to this, rather than the much smaller 7", lower resolution displays used in these 'portable' form factor units.  At least, if you're someone whose workflow doesn't generally have other PC-based instruments up and running in parallel.

Speaking for myself, I'd much rather have seen the LA capability in the DHO1000 and had no DHO900 series.  The DHO800 series could have had more memory (at the same entry price), and the sig gen as an option.

However, as another member has previously said, I look forward to being able to complement my MSO5000 "daily digital driver hot hatch" with a more sedate yet elegant drive for the weekend in analogue country.  The entry price for the DHO800 is very interesting, and entirely in a welcome way.

Just got mine.
I'll shoot a quick unboxing video and put it as an exclusive video on my website.
It's the smallest scope box I've ever gotten!

Thank you for your honest answer, now I understand you.

Yes, "more" is often better... and more expensive.
Why not the DHO924S with 250Mhz with AWG?

It's also a question of where you are looking at it from.
I almost ordered a Hantek. Last week there was a promotion for the 100MHz DSO2C10 for CHF 130.- 

But I thought: No, then I'd rather wait for the cheapest DHO800.
From that point of view, I think you would agree with me?

US$60 difference between 2CH and 4CH according to my pricing from the Rigol website

Yes, fascinating decision, and may very well be what you deccribe.

Agreed.

I took the prices from the batterfly side, including VAT

[mikeselectricstuff]

I wonder if they've connected the USB-C ground to mains earth - would be sensible if they have.
Maybe the supplied 4mm ground lead is just for when running on batteries.

Pity they didn't use a right-angle USB-C plug, as the current one looks like it stops it lying flat. Also a bit of a shame they didn't take teh opportunity to use the rear mouding to provide some support for the plug. Let's just hope the USBC socket is on a sub-board to make it easy to replace.
Would also have been nice to have the facility to screw/clip the PSU to the back, though should't be hard to make something that fixes to the VESA screws

Doesn't that bring shielding problems?

It shouldn't. After all the PSU is usually inside the scope.
Maybe Dave can do some testing on this regard in the review video

In something like a classroom setting, the use-cases are usually limited and more or less known in advance. Plus you are probably buying 10-20 oscilloscopes at a time, so the savings are more significant.

Now also in the batronix shop:

https://www.batronix.com/versand/oszilloskope/Rigol-DHO804.html

What I didn´t recognized so far:
The memory drops down to only 1Mpt/each when all four channels are active...

[Serg65536]

For those who missed the unboxing by Dave.

DHO900 says 10 Mpts , maybe it is an error ?
This is exactly my point that people shouldn't make conclusions before things get fully releases and actually tested.
Also it is 1mV/div, 500uV/div is software zoom...
Simplistic math (single operation per math but you can cascade them, similar to rtb2000)

Unboxing videos are pretty much useless.
 "..it so cute.." is hardly a thing  that is important in choosing a scope.

It is a big step forward for Rigol no matter. Except crippled memory if all channels enabled if it is true. That one is hard fail.

[Serg65536]

It's possible to unlock full memory (like in DHO900) and more than 400 MHz bandwidth (calculated from rize time).

Rise time calculation according to what type of filter?
BW can be measured accurately only with signal generator.

400MHz ? Give my regards to Nyquist...
It makes for a decent 4ch 100MHz scope.. All above is pushing your luck..

[Martin72]

DHO900 says 10 Mpts , maybe it is an error ?

DHO900 got 50Mpts/10Mpts for one channel/all four, DHO 25 for one - I´ve expected  about 5 Mpts when all channels are active.
Strange thing, but not the only one...

[sebyon]

Wow this thing is tiny.

Honestly considering the price point of the thing, VISA mounts and USB-C power, it would make a killer office scope.
